Glossary
Avventurina
Glass of a
yellow-brownish colour,
Tran lucid, in which
copper metal
micro-crystals are
dispersed to reflect a
gold colour, formed by
de-vitrification
(separation from the
molten mass during the
cooling step). It is
prepared by melting the
mixture of transparent
colourless glass with
the addition of cuprous
oxide and iron and lead
oxides. Melting takes
place in a reducing
chamber and the molten
mass should be cooled
very slowly.
Traditionally, to obtain
the best quality, once
the mass is molten, the
oven is switched off and
left to cool on its own
for several days. Once
room temperature is
reached the crucible is
smashed and the
avventurina is found
under a layer of
colourless oxidized
glass.
Calcedonio
Calcedonio Glass with
multicoloured hues,
translucid with opaque
veins, obtained by
adding to the molten
mass, say colourless
transparent glass, a
pigmented mixture based
on different oxides
(generally copper, iron,
cobalt and tin) and
metallic silver that
also contains a reducing
component (carbon or
whatever); the mixture
is partially blended
with the molten mass and
the whole is then mixed
after some time. The
colouring effect is
given both by the
dissolution of the
metallic oxides in the
glass and by the
formation of small
colloidal particles of
metallic silver and
copper, smaller than the
micro crystals.
Canna
One of the fundamental
process of Muranese
glassworks. A very large
number of types of
applications can be
found for this, both
functional and
decorative. The extreme
viscosity of the molten
glass allows it to be
drawn out a certain
temperature, starting
from the end of the
blower's pipe in long,
narrows pipes. When al
layer of coloured glass
is superimposed over a
base of opaque glass it
is possible to obtain
numberless variants of
colour and thickness in
relation to how the
molten glass is drawn
out. Suitably heated
rods are used in
decorations of vases and
figures. All Murano
glass factories have
always used them
extensively with
artistic results.
Corroso
Glass whose surface is
irregular to the touch
due to the use of
chemical agents.
Technically an "acid"
process is caused by the
corrosion of the surface
of the glass that
determines the
disgregation of the
glass lattice with the
formation of a rough
layer on the surface.
This non-uniform layer
causes an effect of
partial diffusion and
reflection of light. For
its execution solutions
of hydrofluoric acid and
ammonium fluoride in
water are commonly used.
By varying temperature,
time in the bath and
composition of the same
it is possible to obtain
very varied effects. The
parts of the glass
surface to be kept
bright are coated with
wax or some other
organic protective
agent.
Fenicio
Decoration obtained by
applying threads of
lattimo glass or
vitreous paste round the
body of the item in a
festoon-like wavy
pattern, obtained by
means of a kind of metal
comb called "maneretta"
passed uniformly over
the surface. This
technique goes back to
the ancient Egyptians
and the Phoenicians to
decorate flacons and
ampoules.
Filigrana
One of the oldest
traditional processes
already in use in the
XVI century. It is done
by applying under heat
on the surface of an
item a homogeneous
series of transparent
colourless glass rods,
with the core of
coloured glass. The rods
are previously arranged
on a metal plate, they
are heated to the
melting point and a
cylindrical item is then
made to roll over them
so that they adhere to
it. The item is then
finished as desired.
Incamiciato
This is a glass
consisting of two
superimposed layers of
lattimo glass and of
coloured transparent
glass on occasion with
the submersion of gold
and silver leaf so as to
obtain an opaque effect.
This is a much simpler
execution than that of
vitreous paste that
involves more complex
technical problems, and
began to be used during
the 20s at almost all
the most important
factories in Murano.
Incalmo
This is an ancient
glass-making technique
to make objects
consisting of distinct
parts joined under heat.
Two or more elements of
different colours are
prepared by modelling
them into the overall
shape. They are then
joined together very
accurately and finished
as desired.
Lattimo
This is a white
milky-like glass in
which the opacity is
provided by the presence
of micro crystals
dispersed in the in the
matrix separated out
when the molten glass is
cooled down. The
microcrystals do not
absorb the light beams
but reflect them, and
thus determine both the
opacity and the white
colouring. In the Murano
area they consist of
calcium and sodium
fluorides and they are
obtained by adding
fluorine compounds such
as cryolite or fluorine
spar, as well as zinc
oxide and alumina, to
the glassy mixture. The
lattimo was introduced
in the XVI century for
items decorated with
multicoloured enamels,
especially refined and
rare. It was later used
as a complement to other
types of process, such
as the "reticello ". It
fell into disuse in the
early Novecento but it
was given a new lease on
life in the late 20s on
the part of the better
names of Murano glass
factories, such as
Barovier & C., Venini &
C. and MVM Cappellin &
C. The latter was the
first to use it without
the addition of other
colours for a series of
geometric vases
exhibited at the 1927
Intentional Exhibition
of Decorative Arts in
Monza. Later, during the
50s, lattimo glass was
adopted by almost all
the glass furnaces on
the island and attained
excellent results in
figures as well, as was
the case of the famous
"Commedia dell'Arte"
figures by Fulvio
Bianconi for Venini & C.
Massello
Full, not blown, glass,
processed under heat by
modeling a block of
glassy mass applied over
the tip of a metal rod.
This process appears in
Murano for the first
time in the late 20s on
the part of Flavio Poli
at the I.V.A.M. furnace
of Libero Vitali's where
he designed the first
figures in full or "massello"
glass.
Mosaico
This kind of glass is
obtained melting glass
pipes (=canna) of
different colour: a set
of pipes is prepared on
a metal plate according
to a given design,
heating them up they
melt each other. The
result is a
multicoloured plate that
can be used for
different complements.
Murrina
This is one of the
oldest processes known
to man the first
examples go back to
Roman times. Items made
in this way were already
existed in the XVI
century. Making a
murrina consists
essentially in preparing
a sheaf of multicoloured
glass rods, arranged so
that its cross-section
is according to a
predetermined design. It
is then heated and when
the melting point is
reached it is drawn out
until the de-sired
diameter is obtained.
After cooling, the rod
obtained in this way is
cut up into small disks
of variable thickness,
ranging from just a few
millimetres to a couple
of centimetres, whose
section has the
previously made design.
They are now ready to be
used in several ways.
Their use in the
production of several
kinds of objects is done
in two different ways:
The first consists in
preparing on a metal
plate a set of murrine
according to a given
design, heating them up
and then making them
adhere by rotation on
the surface of an item
with a cylindrical
shape, still connected
to the blower's pipe.
After this the item is
finished as usual, on
occasion coating it with
a layer of transparent
colorless glass. The
second more suitable for
the execution of dishes
and bowls, has the
murrine arranged inside
a die in refractory
material, trying to fill
in the empty spaces with
glass powder so as to
get a homogeneous mass.
The whole is then heated
as appropriate so that
the murrine are welded
together to form a
single object. After
cooling it is finished
with the grinding wheel
to remove any
irregularities that may
be due to heating
process.
Pasta vitrea
This is a coloured
opaque glass whose
preparation is based on
the same principle as
the lattimo glass. In
this case, however,
white microcrystals are
dispersed in a colored
vitreous phase. Others,
differently, are
obtained with coloured
micro-crystals dispersed
in either a colorless or
a colored vitreous
phase. In the first case
lattimo is used (microcrystals
of calcium and sodium
fluoride) or white
enamel (amore intense
white completely opaque
even in a thin layer,
generally obtained with
micro-crystals of
arsenic and lead)
dispersed in a
transparent coloured
glass. The white
microcrystals, in
addition to making the
glass opaque, soften the
colour of the glass in
which they are inserted,
that must contain a high
percentage of colouring
agents. In the second
case "cores" are used:
these are semi-finished
crystalline structures
based on lead antimonate
or stannate that are
yellow or red. These are
added to the molten mass
just before processing
because they are
compounds that dissolve
easily.
Pezzato (lavorazione a
tessere)
This glass is like a
patchwork with elements
of different colours and
is obtained as follows:
on a metal plate a
series of segments of
flat rods, according to
a given design are
arranged. The plate is
heated to take the
segments back up to the
melting point: at this
stage the set of molten
fragments is made adhere
by rotation to the outer
surface of the vase
still on the tip of the
blower's pipe. After the
pieces have been joined
together, they are
finished by appropriate
smoothing over and
modelling.
Pulegoso
Glass with a spongy
appearance, with a great
many air bubbles, to the
point that it is almost
opaque. The homogeneous
and refined molten mass
(with no air bubbles or
impurities) is
vigorously mixed in with
salts (generally sodium
carbonate or
bicarbonate) that
decompose due to the
heat and liberate gases
(carbon dioxide)
dispersed in the form of
bubbles of varying
diameters.
Reticello
This is a variant of the
"filigrana" already
known in Murano in the
XVI. It is obtained by
joining two conical
vases under heat,
covered externally with
thin coloured rods, one
arranged clockwise and
the other anticlockwise.
A network is thus formed
with a rhomboid-like
mesh. The rods with
different thickness,
within each quadrangle,
cause the characteristic
air bubble.
Sabbiatura
This is a process to get
the same results as the
"acid" process without,
however, the latter's
negative aspects, linked
with the use of toxic
substances. Sand or
alumina powder is
sprayed onto the
glassware with a
compressed air device.
The impact of the
granules on the surface
causes microfractures
that make it opaque.
Sanding is marked to a
greater or lesser extent
by an appropriate
adjustment of both air
pressure and granule
size. Used mostly on
flat panes, this
technique has also found
application in the
preparation of some
drawings by masking some
of its parts.
Scavo
This is a glass that
imitates the effect
caused by long periods
spent underground,
typical of glass objects
found during
archaeological diggings.
During manufacture, a
mixture of several
powders is dispersed on
the surface of the
object at a temperature
of about 800 C. These
adhere irreversibly and
give the special effect
of opaqueness and
colouring. To improve
adhesion the piece is
heated again. The powder
mixture contains melting
components (carbonates
or nitrates that
decompose under heat and
act as binders; inert
opaqueness (talcum,
silica, etc.) other
colouring agents. This
technique was introduced
in the early 50s.
Siderale
This is a glass invented
in the early 50s. The
procedure for its
preparation was as
follows: a large
concentric-ring murrina
was made with two
alternating colours; it
was then heated again
and applied while hot to
the item being
processed. After a first
finishing step, and
after cooling, the item
still with an irregular
shape was modelled and
polished at the grinding
wheel with an extremely
long and delicate
operation. With this
complex and laborious
technique, a limited
number of items was
made, very rare and
refined, that for their
essential shape and
decor represent the very
best Muranese
production, with a level
of quality that compares
well with that of
northern Europe.
Smalti (enamels)
Enamels wide spread in
Murano since ancient
time. While up to the
mid-nineteenth century
every craftsman made his
own on the basis of very
particular and jealously
kept recipes, it later
became fashionable to
adopt vitreous enamels
produced on an
industrial scale. They
must have the following
features: applied cold
to the item during
manufacture, they must
fuse at a temperature
lower than that of the
glass, their colours
should not fade at high
temperatures and they
should Ave a coefficient
of expansion as close as
possible to that of
glass to prevent
breakages during the
cooling stage. Once the
decoration is finished,
the item is placed in a
small "muffola" oven
where it reaches a
temperature of some
550/600 C to allow the
enamel to fuse without
deforming the item. In
the Novecento this
technique was used to
make copies of ancient
models, but a few
exceptions.
Sommerso
This is a glass coated
with a thick layer of
colourless transparent
glass, or with a glass
which has a colour
different from the one
of the backing. It
consists of a layer of
coloured glass with the
inclusion of air bubbles
and gold leaf, more
rarely with the
subsequent application
of rods in pulegoso
glass, coated with a
colourless transparent
layer about one inch
thick. Many Muranese
glass factories
extensively took up this
technique with very
considerable results.
Tessuto
A glass invented during
the late 30s it is based
on the traditional
filigrana, technique
with particularly thin
rods used in this case,
joined one to the other
with especially refined
alternating colours. On
occasion to enhance the
surface even further, it
was lightly "battuto" at
the grinding wheel.
Zanfirico
This is a glass rod
executed with the same
procedure as the "murrine".
A sheaf of rods of
different colours is
prepared with a given
design, it is heated to
the melting point; two
metal rods are then
attached at the ends of
the molten mass while
two maestros draw it out
and impart a movement of
rotation. The fluidity
of the material is such
that it can be twisted
at will to assume its
characteristic
spiral-like shape
inside. This type of
object was already known
in Murano in the XVI
century with the name of
"a retortoli " glass.
The current name of "zanfirico"
is taken from the
Venetian nineteenth
century dealer Antonio
Sanquirico who proposed
this process anew.
A Brief History of
Murano Glass
The tradition of glass
making on the islands of
the Venetian lagoon goes
back at least a thousand
years (the first
official, dated document
mentioning a Venetian
glass blower was drawn
up in 982).
Previous to this is has
been recorded that the
glass was created
throughout the world,
and used along the many
trade routes from as far
as Afganistan and
Africa, as currency.
Over time the centre of
trade moved to Venice,
and the glass making
tradition (to become
known as Murano glass)
slowly died in all
regions except for the
island of Murano. Long
before the end of the
13th century there were
already established
glassworks on Murano.
This is confirmed by a
document written by a
Benedict monk, Domenico
called "Fiolario", who
manufactured phials for
use in the home. There
is no certainty as to
the shape of this phial
since not one, neither
whole nor in pieces,
survived to the present
day.
The technique used to
make the phial was that
of blowing into glass
using those instruments
that the late Roman
glass blowing activities
had passed down through
the ages. Later the
technique was refined in
Venice more than any
where else in Europe
because of the trading
contacts that the
Venetians had with the
Orient and above all
with countries that
already had an ancient
tradition in glass
blowing such as the
Phoenicians, the Syrians
and the Egyptians. Such
traditions, renewed in
the celebrated furnaces
of Islam, were an
occasion to reconstruct
both Western and
Oriental knowledge and
techniques there by
giving the Venetian
production a uniqueness
that made their glass so
important throughout the
world over the course of
the centuries. Today
Venetian glass
production is at it's
pinnacle, and is world
renowned for it's
quality and form.
By verdict of the Doge
and carried over by Doge
Tiepolo in 1291, the
island of Murano was
declared a true and
proper industrial area
and soon became the
capital of glass
production in the world.
The Doge was represented
by a head of state and
flanked by a popular
council called Arengo,
among the various
privileges they were
afforded was the so
called "Libro d'Oro" or
golden book where the
names of the most
important families were
recorded. The icon of
the "oselle" or the
conservation of the
symbol (the rooster
carrying a fox on it's
back and a serpent in
it's beak) is the
extraordinary concession
that the families of
Murano shared with the
nobility of Venice. The
affinity between Venice
and Murano is curiously
seen in the morphology
of the two cities which
presents the same public
squares, streets,
internal canals and even
the same "Grand Canal"
which runs through it.
It was deemed necessary
to construct an order in
the productive cycle
from the buying of raw
materials to the
formation of Glass
Masters and the
preservation of the
product. These rules
were transcribed from
classic Latin into a
more known language.
This transcription took
place in the first half
of the 1400's with the
writing and approval of
"Mariegole della arte
dei verieri de Muran"
(rules of the art of
glass-blowing of Murano)
and is preserved at the
Correr Museum in Venice.
The manuscript with a
frontispiece
illustrating Saint
Anthony Abate, patron
saint of glassblowers,
is bound in a velvet and
gold cover (17th
Century). Along with the
category of glass-blower
who was dedicated to the
production of blown or
hollowed out glass other
categories were added
such as mirror-maker and
window-pane maker and in
particular rolled glass
bound in strips of lead
(leaded glass maker).
There was also the
category of glass
flower-maker, bead and "conterie"
maker. The name "conterie"
or counter is thought to
have come from the habit
of using beads almost
like currency. All of
the glass-making
specialties were
represented in the
internal council which
were elected each year
and were composed of
furnace owners and the "Stazionieri",
who were entrusted with
the job of selling the
final products.
Hierarchies grew up
around the furnaces that
governed the production
activities in the
"Piazza" (local square)
with the "maestri"
(glass masters), "garzoni"
and "garzonetti" (lackies),
"serventi" and "serventini"
(trainees) and not least
of all the "forcelanti"
(glass-cutters) who were
at the direct dependence
of the Glass Master to
whom which he paid
solicitous respect
seeing in him not only a
teacher but above all as
mentor.
On Nov. 8th, 1291, the
Consiglio Maggiore (the
Great Council a
governing body) decreed
that all the furnaces
currently operating in
the town should be
demolished but at the
same time it also
authorised the
construction smaller
kilns, with more
restricted production.
Over time, knowledge
about glass and its
properties has been
continuously added to,
and many new techniques
have been developed.
Lead crystal was added
to the repertoire of
Venetian glass makers
during the Renaissance
period. Angelo Barovier
was the first to make
it, in 1480. A glass
mirror made in 1493 can
still be seen on the
island. Angelo Barovier
also developed another
technique called
“Caledonia”.
Sophisticated glass
techniques such as
enamelling were brought
in from the east at that
time, but the Sack of
Constantinople also
brought Venice absolute
dominance of the trade
in luxury goods around
the whole Mediterranean.
From an early date the
Republic organized its
glass trade and industry
in a conscious effort to
achieve a worldwide
monopoly.
Glassmakers were already
subject to some rules in
the 12th century. The
famous Capitulare de
Fiolaris dating from
1271, is the first
statute of the
glassmaker's art,
containing rules and
regulations for all
people involved in
glassmaking, including
the furnace owners and
the youngest
apprentices, who were by
the all organized in a
guild of glassmakers.
The "Capitulares" was
regularly amended until
the last version was
issued in 1776.
In arond 1527, a further
new and extraordinary
technique appeared on
the island: filigree
glass, which has a
design of overlaid glass
rods.
Over the past 100 years,
the innovations have
been of a more
technological nature.
Instead of using bellows
to make a wood fires
burn, glass blowers
began to use oil fired
kilns and then, later,
butane gas which offers
almost unlimited
possibilities for
developing high
temperatures and
obtaining top quality
materials with no
impurities.
The high quality
silicate sand used to
make the glass is
imported from nearby
France and Switzerland.
It is mixed with sodium
carbonate and calcium
and borax from the
U.S.A. Sodium nitrate
and antimony are used to
obtain clear glass and
diverse mineral oxides
are mixed together in
order to obtain the
hundreds of different
shades and colours we
see today.
Before the Second World
War, Venice’s glass was
well known in Europe,
but since then its
popularity has spread
and it is now sought
after all over the
world.
Murano glass has know
moments of glory over
the centuries as well as
moments of decline.
However it has always
been characterized by an
obsessive search for
quality. In fact
Murano's motives in its
pride has always been
its aesthetic quality
which has often
contrasted with its
competition and has
frustrated attempts at
imitation. From its
poly-chromatic glazes
and the gold in the
cobalt blue of the
Barovier cup to the
lightness and
transparency of its
glasses; from the
delicateness of the
lattice-work to the
originality of Murano
glass; from the mosaics
to the counting beads;
from the panes of glass
to the mirrors, it all
represents the original
history of glass. Just
as painting and
sculpture, interior
design, mode and
jewellery have become
entwined in the history
of Murano, considering
the versatility of the
material to adapt to
other forms of artistic
expression.
