Cristiano and Andrea De Biasi

Cristiano and Andrea De Biasi have followed in their father's footsteps. They are the sons of Virgilio, who started colouring precious seed beads in the '50s. Having mastered the necessary glass-making methods, Cristiano and Andrea introduced their creations - at first mostly clocks and frames - on the domestic and foreign markets. They addressed their products in particular to retailers, distribution chains and specialized ateliers.


By using the most valuable types of Murano glass, such as zanfirico, avventurina, pastel colours, and by combining these glasses with authentic gold and silver leaf, Cristiano and Andrea produce innovative collections of jewellery and plates.


These combine the thousand-year-long tradition of Murano glass-making with modern creativity and the ongoing search for new dimensions and colours.For the first time the collections that are present on this site have been put up for sale directly and are also displayed in our show room in Via Navagero, a couple of meters away from our workshop. The fact that we are putting our products directly on the market is a point of great pride for us.The De Biasi glass factory is also authorised to display the trademark Vetro Artistico di Murano, which is the only guarantee for all unique and original Murano products, created with Murano glass. (Promovetro e Vetro Artistico di Murano).


Cristiano and Andrea are presently collaborating with specialized retailers in Italy, Japan, the US and France. They also collaborate with Italian and foreign designers, and create models based on projects.For wholesale orders please contact Cristiano or Andrea De Biasi directly..

By using the most valuable types of Murano glasses such as  avventurina, zanfirico, pastel colours, and by combining these glassess with authentic gold and silver leaves, Cristiano and Andrea produce innovative collections of glass  jewellery and glass plates.

These combine the tousand year long tradition of Murano glass making with modern creativity and the ongoing search for new dimensions and colours.

In our collections of nacklaces and pendants made with  Murano glass according to the most ancient tradion, you will find many ideas for your gifts or for your shop.


We always had a special interest for new shapes and new items, simple items, but

made exclusively in Murano glass, and we always tried    new    ways    to    melt,

fuse, give shape to this wonderful substance.

We begun using gold and silver foils inside two or more different layers of glass, we added also murrinas into this technique,

and we get to a new dimension of pendants; you can see the shineness of the

items in these pictures.

Above, you can see a sample of our glass chopsticks,a light blue sample,  and we are proud to tell you that we are we the sole company in Murano that can produce these lines of glass chopsticks, with  plain glass and also with murrinas.

Dealing    with    new    shapes    and    colours    involves     a    challenge;    but    we    think    that

creating new and beautiful lines of items is a process that goes well beyond the day to day struggle to stay in the market: when something is made with the right interest and passion, the results are evidend.

Starting from bigger items such as glass frames, plates, and mirrors, we focused ultimatly on smaller items, such as glass pendants and earrings. We can develop new shapes and we can make a lot of combinations of colours using different murrinas, so that our collections are continually updated; almost every month we add some new shapes of glass earrings to our existing collections and we add also some new colours of pendants, all of them made or with murrina, or using gold and silver leaves...

Glass portraits were our flagship when we started our business: we produce them both for our two shops in Murano, but also for shops, retailers and wholesalers all over the world, included shops in the isle of Venice.

We credated many different colours over the years,  finding that real gold and silver foil,although very thin, could stand the glass melting process that leads to the creation of our glass plates, from which we cut the bars used to make the portraits. Gold and silver add to our glasses a special shineness, add some sharpeness to the combination of colours inside the glass plates, and make the frames more classic, in the case of gold foils, or modern, in the case of silver foils. 

In the three pictures above you can see one of the last  collection of glass portraits: a portrait made with small rectangular "mosaics", cut from our glass plates, with a size of more 1 inch per 1 cm.

The final effect of this portrait is an item at same time classic and modern, becouse it combines both silver and gold foils together. You can also note some special "pieces" of multicoloured glass, some  sort of "islands" of glass, small pieces of glass that have a triangular, or square, shape, and have concentric lines of different colours:

those are the famous "murrinas", or "murrine", as we call them.

We produce different sizes of portraits for each colour:

a small size with external measures of 10*13 cm, a medium size of 14*19 cm, a big size of 17*21 cm, and a extra large size of 21*26 cm. The most sold size is the medium size. Each frame is made with  glass bars that are 2 cm wide and almost 1 cm/1.2 cm. thick, and this, together with our shiny colours,  gives weight,value, and durability to the items. Each frame is sold inside  an elegant black gift box carrying the name of DE BIASI COLLECTIONS.

When it comes to produce bijoutery items, such as  pendants,  earrings,  rings,  necklaces, the producer can take  inspiration from the market and items around himself....but he wants to make something  original and different,

he has to find his own way, method, and environment: our pendants were born like this, making many different attemps to create both new shapes and or new colours, using the different combinations of the small murrinas we told you before, and sometimes adding a special effect to the plain glass, such as engraving the black glass  as  you can see in the  picture below: it so seems that glass turnes into wood, becouse the engraved glass seem wood; you can see the engraving effect in the lower  part of the pendant...and we think that this may add some movement, some originality, some warmness , to our glass pendants  

About glass pendants made with murrinas, our preference has always been towards the round shape, and we produce

three different sizes of murrina pendants: a round shape of 3 cm. diameter, a round shape with diam.4 cm,. and a round shape with diameter 5 cm. The 3 cm size is generally a more "casual" size, whereby the 4 cm. size is the  more

chosen size. The main tonalities produced are the turquoise/blue , purple, black and white, red/white/black, and green, and inside these tonalities you can find tens and tens of different items, just becouse the combination of murrinas and plain glass are almost infinite!

Below you can see two round shape pendants, tonality black and white, with a diameter cm.3. Inside this tonality you can find many different pendants, for each size. The two pendants are matched with thin silver necklaces, attached to them with a nickel free hook, made with no allergenic metal, zamac, an alloy made with zinc, aluminum, magnesium and copper           .The quality of this metal

hook is such that it does not change colour over time! Each pendant is hand made, chopping the murrinas  bars into 5/6 mm long pieces, and positioning them inside a round mould, that will undergo a 6/7 hours melting process, fusing together the murrinas. But the process does not end here, becouse what comes out of the electric kiln is not the final pendant: the "raw"pendant, in fact, has to be polished, grinded, so that it can be put one more time in the                                                    electric kiln, for the final process.                After the second process in the kiln, the product is ready to be sold. 


We create the combination of colours of each pendant, the "texture" of the pendant. We can also develop special designs

when required by our customers, especially for items sold as company gift and produced in quantities bigger than our

normal standard. In this case can develop some samples to submit to the final judgment of our customer.

We strive to offer our customers the highest quality for our pendants and luxury bijoutery, trying to improve techniques

we use to forge them: please take a look at the two pictures below, to see how accurately the small pieces of murrinas have been assembled together, the design is fluid, there are no holes or imperfections in the texture: the pendant below has been made using , of course, Murano glass murrinas of different colours, lagoon green, white, black, and again white and green, creating a raibow of colours that at the present moment is a leit motive in our textures.


See the profile of this 5 cm (2 inches) large round shape pendant, it looks like a lens,and the thinness of the pendant is obtained through a work at the grindind machine (in Italian, the "moleria") that grinds out a part of the glass,after the first 

meltin process in the kiln, leaving a thicker center of the pendant, and  gradually thinner borders. 

The metal choker used in the pictures is a nickel free item, made in a non allergenic alloy, used specifically for bijoux purpose;  each pendant  of ours can be matched with this metal choker.

Earrings made with murrinas are among our best selling items. To produce them, we use  small murrinas to compose the texture (the glass plate) and, afterwards, it's required a patient work of cutting the plate in small triangular shapes that will be grinded and made thinner, 2/3 mm thin, and finally, afterthe grinding step, they will be put in the kiln again;

this last passage will make the items as shine as you can see in the pictures.

For our glass earrings and for our glass

bijoutery we only use non allergenic metal

components that don't change colour with

the passage of time.

But we can use sterling silver components, if this is required by our customers.

Each item in this gallery can be purchased on line, but in our shops in Murano we have

a larger collections that encompasses the

newest items and also older collections.

Each couple of earrings is sold in a stylish

black gift boxe, with the murano glass trademark lablestick and with a small leaflet as guarantee of the artigianal production made  in the isle of Murano.

We cater not only to private customers, who can visit our shops during the year, but also to retailers and shop owners who can be interested in exclusive  items made with Murano glass, with innovative shapes, and

renewed and updated  every few months. We can wide our horizons and move our production

from the smallest items such as  luxury glass bijoutery to bigger items, such as plates, table clocks, wall clocks, mirrors, paperweights...

Glassware can be fine and stylish even if its created with plain glass, without the use of many colours and shapes.Our passion leads us to make items with a single colour, using our grinding machines to add  a new dimension to the items. Below you can see plain glass plates with the shape  of a venetian "gondola", grinded

on the internal side, 40 cm. long.....

We think that quality is important. We recognize that there are many good producers of glass items, not only in our country.

We also recognize that glassware and glass items produced in this isle of Murano have an internal mixture of craftmanship, style, skill. The  "Artistic Murano Glass Trademark" has been created to legally protect and preserve the originality of the glass items produced in this isle, preventing the damages  that a  continuous counterfeiting can have on the productive and economic environment of Murano.


We are authorized to use the "Murano Glass Trademark" lablestick on each product that we make and sell; the lablestick  cerifies the originality of the item, the Murano glass quality, and our customers have always the certainty that they purchased something that is "TRUE MURANO GLASS".



Beside "glass fusion", our main production technique, we use the "torch flame" technique, that allows us to produce fine bijoutery items such as necklaces, bracelets and earrings, using murrinas in the same tonality.

In our shops in Murano you can find a great assortment of items, all sold in elegant gift boxes. In our shops you can buy our items without any passage from the producer to the retailer, becouse we are the producer. It's for this, that beside good qualiy, our items have also a good price!

                                                                  But what are murrine?

Murrine are glass rods that contain a design , a pattern. Generally this pattern is made by concentric lines , squared lines, or circular line; the pattern can be a star, or a small flower. The pattern is revealed whe the rod is chopped in thin pieces, that wi'll be used to make up a special texture.

We arrange the murrine in a ceramic plate  made of fireproof material. This plate is positioned inside

a kiln, ultil the murrine fuse in a single plate. We  cut and drill  that plate to obtain the desired shapes.

In the pictures below we present two  other examples of murrine rods and chopped pieces.

The murrine are arranged over the ceramic plate. They are manually positioned one by one, so that to create the desired texture. This part of process is  very demanding, becouse almost no room must be left between a murrina and the other closeby murrines, so that the fusing process may happen as smoothly as possible, without leaving any "air bubble" that could ruin the entire work of a workday.

Below, we present two photos of how a plate of murrine appear before the kiln starts its 8 hours long fuding process.


When the fusing cycle of the kiln is over, the "almost" final product can be grinded and smoothed and polished, before the second and final  fusing cycle. The items below are plates just out of the first cycle.


The plates in the two pictures above are round shape plates with a diameter of  22/23 cm, just think how long it takes to arrange all the murrine in the desired texture! These plates have to be smoothed and grinded

on the borders becouse, as you ca see, borders are quite rugged an uneven. These plates have to be grinded also on the external side, the visible side, so that the texture of the plate will look more uniform after the second cycle into the kiln.

The plates have to be positioned over the moulds for the second fusing cycle, that will render  the concave shapes to the glass plates.... Ultimatly, we get what has been photographed below...


Finally, after the secong fusing cycle, we get the final product...



Below a zoom up of Vetro Calcedonio rock and small speckles of Avventurina, special kind of glasses that we use every day for producing pendants, necklaces, portraits and plates.

In nature, chalcedony is a particular crystalline form of silica, a mineral, and can assume a wide range of colours, most commonly grey, grayish blue,shades of brown...

In the middle of the fifteen century, glass masters invented the Chalcedony glass making technique, involving the use of different combinations of colours, such as blue, grey, green.. The final outcome, called Vetro Calcedonio,   presents many different hues in the same piece, different undulations of greyish, blue, green shades..

You can see some samples of Vetro Calcedonio, Chalcedony glass, in the pictures above, in the form of  small pieces of stones.

We use  those stones to obtain 1.2 cm. thick  layers of material that will be fused inside black(or avory) glass, and  a thicker plate of crystal clear glass. We use also Avventurina (the small brownish speckles at the right of the picture). With  the plate that we obtain, we can finally produce a particular collection among our range of pendants...... as you can see in the 2 pictures below...


You can see the rainbow effect  and the undulation of colours in the two pendants above. Once the plate "Calcedonio " ir ready to be cut in the shapes of the pendants, a long and demanding work is required to grind, first, and polish, afterwards,the pendants in the required shapes. And, after all this has been done, the items will be put

again into the kiln, for their final melting cycle. Only a new fusing cycle can, in fact, give such brightness and brillance to our glasses.
