Murano 101: Bubbles Bubbles and more Bubbles!!!
« on: April 05, 2005, 10:41:16 PM »
Hi Everyone!
As the new moderator for the Murano section I will be bringing new topics, examples, and information for everyone to read and participate in. This new Murano 101 topic, as here in the US we call the 1st (101) introductory class to a College course, is all about BUBBLES!!!

I have compiled a few images of Murano pieces in my collection with bubbles as decoration...

First I'll start with one of Alfredo Barbini's designs, using 1 layer of Controlled Bubbles or "Bullicante" over white. Usually the Gold Fleck will cause the piece to have a quilted design. It depends if the bubbles are on top of the gold or below it.

This second image is of an Archimede Seguso bowl, with 2 layers of Controlled Bubbles, which I called "Bollicine" for a long time to differentiate it from the "Bullicante" (1 layer). It is however called "Bullicante" in books so I will refer to it as such.

This next one is from a Barovier piece, where he used multiple rows "Cordonato," not layers of bubbles, one over the other, like Seguso.

There are many other combinations in which this bubbles are used, but they are in 1 form or another, "Controlled."

On the other hand this next examples go into something different. They use bubbles as the main part of the bowl or vase. The bubbles become the background, the color, and the texture of the piece.

Here's a piece which has very, very tiny frothy bubbles "Pulegoso" decoration, and has the white color because of it. The piece also has little open bubbles on the outside, but because they are so tiny, they are hard to feel with your fingers.

A little more intricate is this "Pulegoso" or "A Bollicine Sommerso" piece, where the bubbles vary in size, from "Froth" to larger bubbles all dispersed throughout the vase. It is also covered with a thin layer of Pink glass and Gold Flecks, so there is no texture.

Last is a close up of a "Pulegoso" vase, that has no decoration or any extras, other than a light Iridescent surface. This shows how the bubbles are everything to the vase, Color, Texture, and Form!

Hope this helps all of you collecting Murano, and those others looking at the board! Thanks again! Comments and new posts are welcomed!

Interesting Javier. What were the techniques used for creating the bubbles of each type?

Hello Frank!
Thanks for the post. I will look and see what I can find, although reading my books I didnt see much on how each technique is executed. Will look and try to find more info.

Bollicine
In Century 20 Pina defines this as "tightly packed bubbles" and Gable in Murano Magic explains that the technique uses "an oxygen rich mixture"...." to produce glass filled with bubbles". In the sommerso example he shows, the bubbles look very many, randomly dispersed and of different sizes.

From your example also it would seem that bollicine and pulegoso give a similar effect but maybe ony bollicine is used with sommerso layering ?

Puleg0so is attributed to Martinuzzi for Venini after 1928 according the Glass Museum article by Ursula Losch here http://www.glass.co.nz/Venini.htm

Early Pulegoso (http://www.museiciviciveneziani.it/images/Vetro--pulegoso-verde--Mart.jpg) found in Glass museum here http://www.museiciviciveneziani.it/frame.asp?sezione=incostruzione follow > Glass Museum > Layouts and Collections > Twentieth century.

Hi Peter,
Yes, the Pulegoso is without the clear glass layer, which gives it the rough texture to the outside.


"a bollicine" (with small bubbles) - Glass, foam like in appearance, with fine air bubbles, created by adding wet wood or an oxygen-rich compound to the melt."

"pulegoso" - Glass, foam-like in appearance, with coarse, dense bubbles.

Definitions from the book "Italian Glass - Murano • Milan 1930-1970, by Helmut Ricke and Eva Schmitt"

Hi Frank,
I belive Martinuzzi was the inventor of the technique 1927-28, but I didnt want to put his name to the example, because he wasnt the only one using the technique in the 20's-30's. Seguso alo did early Pulegoso pieces for example.

Hi, I have a small shell shaped bowl that is done in three layers (sommerso?): clear exterior; green interior and what appears to be a frothy, semi-opaque whitish layer in between. I can't see any clearly defined bubbles but the whitish glass layer looks almost grainy. Would this middle layer be considered "bollicine"? Thanks for any direction on this issue.

Hi Bidda,
Your piece looks like it has bubbles in it from the making process.
Some opalescent pieces will have that.
