Beaker | Techniques of Renaissance Venetian-Style Glassworking

This video shows first the two types of required canes being made and arranged in a pattern on a ceramic plate. After the canes are fused together, a thick, cylindrical bubble of glass is rolled over the canes so that they become attached. After reheating, glassblowing is used to make the beaker.

Between about 1500 and 1725, Venice was nearly the sole supplier of fine luxury glass to the royal and aristocratic, the wealthy and powerful, throughout Europe. The Venetian government went to extreme measures to protect its lucrative and prestigious monopoly by isolating the highly skilled workers on the nearby island of Murano and severely restricting their movements. However, with the promise of personal freedom and the hope of fortune, they gradually fled the lagoon to set up workshops in a variety of locations on the Continent and in England.
The Techniques of Renaissance Venetian-Style Glassworking - renvenetianstyle.cmog.org - presents detailed 360° photography and high-definition video related to objects from nine glassworking centers influenced by Venetian style as researched by master glassmaker and scholar William Gudenrath.
The resource is a follow-up to Gudenrath's popular Techniques of Renaissance Venetian Glassworking (2016) also available free online at renvenetian.cmog.org.

Thanks for watching!

[@evansmommy50]

Very interesting. But, I marvel how this gentleman can work with no gloves or apron--yet apparently no grotesque scars from mishaps.

[@rcWizzard]

Bill, WOW, you've been working Overtime, glad to see you back!!

That ball cut free at 5.02 looks like it could be an awesome drawer handle.

[@joshschneider9766]

People do all sorts of stuff withem.

[@txartchick5594]

I was thinking magnet but I like your idea a handle of something. I hope he does not toss it ?🙄

[@joshschneider9766]

We usually toss the cut offs but ive saved a couple of mine.

[@txartchick5594]

Beautiful and with such ease .I watched your hand movements .stunning I'm speechless .....so beautiful 😁

[@corningmuseumofglass]

Bill definitely makes it look easy. Thanks for watching!

[@MatigrisSH]

Absolutely gorgeous

[@corningmuseumofglass]

Thanks for watching!

As goes without saying, Bill's work is amazing. He says at the start that historical canes are usually transparent in the centre - is this simply because this was the most abundant glass at the time, or are there other reasons as well?

[@chazzbranigaan9354]

I know clear glass is basically free and colored glass rather expensive so I'm sure that's possibly a contributing factor

[@joshschneider9766]

Conservation of colored glass was extremely important back then, so they took advantage of the optical properties of glass by using clear cores. Transparent colors over opaque colors, mostly the white and transparent colors but sometimes other opaque colors, is called "veiled" cane. When viewed in hand the lensing of layering makes it almost glow. The venetians were and are very fond of veiled cane.

[@joshschneider9766]

Today we have manufacturers doing the color making most of the time. Most shops don't have color pots but rather use pre made color resulting in colored core clear overlay simple cane. They didn't have that luxury as they had to manufacture their own colors hence clear cores. Just makes good logical sense when dealing with crucibles of color dedicated to cane work.

@@joshschneider9766 Thanks very much for your replies. Is this all from experience, or are there any books you might recommend me?

If you make a bunch of canes at 20 feet in length each, how many beakers does that make?

[@corningmuseumofglass]

That's hard to estimate but one long pull of the cane should make at least one beaker. Thanks for watching!

[@joshschneider9766]

240 inches divided by 4 equals 60 segments. Sixty segments divided by 8 used in the basket is 7.5 beakers off that pull. But every pull is unique so that will never be the same twice.

[@peggyt5409]

Does the molten colored glass have a different texture or feel compared to the clear glass?

[@elic1738]

No, the colored glass feels exactly the same. Even if it did, the canes have a clear coating so you wouldn’t feel it anyway

[@janisfroehlig7744]

If you're asking about when it's hot, not really, not enough to change what you'd do with it... most of the time. There is a calcium white that behaves like it's colder, some copper-based colors can have what feels like a rather sudden liquification when reheating, and other colors do some other different things. It depends on the minerals or salts in them., but they're formulated to avoid oddities. Glass colors are like co-workers, you need them all, some you like to work with more than others, some just turn out amazing product, but in the end, people are people. Compatible glasses are pretty much just as predictable.
