Three-bubble Goblet with Filigrana

This goblet is made using filigrana, a style of blown glass made with colorless, white, and sometimes colored canes that originated on the island of Murano in the 16th century. The canemaking and glassblowing processes are shown in the video. Learn more about this object in The Techniques of Renaissance Venetian Glassworking by William Gudenrath renvenetian.cmog.org/object/th...
The Venetian glass industry enjoyed a golden age during the Renaissance. By the early 1500s, the wonders of Venetian glass were well known throughout western Europe. Not well known, however, was how these objects were made. Until now. The result of 30+ years of research by William Gudenrath, The Techniques of Renaissance Venetian Glassworking - renvenetian.cmog.org - presents 35 complete reconstructions of Venetian glassmaking techniques through detailed 360˚ photography and high-definition video.

The amazing thing about glasswork is that even if most jobs in the future are taken by robots and such, glasswork is something that is exclusive to humans and will be for a very long time.

[@SladeBallard]

It's incredible the amount of dedication and talent it takes to make something that looks so simple at first glance.

[@joshschneider9766]

Well Bill doing it solo is a crazy high level skill achievement. Normally teams make the cane then other teams use it. Its awesome to see Bill do solo rollups.

[@qiqi2692]

I’ve been in awe of Bill for some years now. Does he do exclusively historical techniques and work, or does he uses them also to create temporary modern works ?

[@ATMAtim]

Bill is such a pleasure to watch! He makes it look so easy but I know it is not. We'd love to see him in action some day.

[@TaurusPresents]

Beautiful. Real craftsmanship. I am addicted to hot glass and also have several glass blowing videos on my KZbin channel.

[@Beevreeter]

What fantastic skill, I'll never look at glass the same way again!

[@Adam-ou3fh]

Well said mate 👏 that is a skill that would take a lifetime to learn I have watched loads this past week

[@joshschneider9766]

There's actually a vid of bill in 1989 doing some early versions of this stiff. He's constantly practicing, its really amazing to see his progress.

It's always interesting to watch a master. what took years of practice looks effortless.

[@belacickekl7579]

Just that little trim that you see there at the end is a really, really difficult skill to master!

[@Eralen00]

I've never done this before but it does look very difficult to me. I can only imagine how tough it is to balance the heating, spinning, shaping, all at the same time. You almost forget that's glass they're working with, one of the most fragile materials we come across day-to-day

[@joshschneider9766]

Hellaciously high temperatures too. When the twisty cane is being stretched its around 1400 and rocketing down to room temp

Burano, the neighbor to the island of murano, where glass like this is made in venicr, is famous for its lace. Many cane patterns are named after lace types and many are direct imitation of specific lace patterns. Must have been quite the household with lace tablecloths matched to lace patterned wine goblets lol

Centrifugal force is what pulls the piece away from a rotating rod. The Centripetal force would be the force that is keeping it from flying off the rod in the opposite direction. Similar but distinctly different.

[@robdeskrd]

That was fucking cool

[@TheMarkJoergensen]

How on earth are they making the canes the exact same thickness in the middle? One would think it would be a continuous taper from a thin middle.

[@joshschneider9766]

Controlled cooling. When reheating and marvering repeatedly before pulling you're equalizing temperature through down to the core so it stretches precisely evenly. Also why Bill was wriggling it at the start in the straight cane one.

[@joshschneider9766]

But also the ends near both pun ties do end up looking like pencil tips. Off a 30 foot pull with that much precision probably 27 or 28 feet was perfect. Because bills been doing it since the mid 80s I think. Maybe even earlier not sure.

What type of kiln is that?

[@corningmuseumofglass]

Jim, the kiln is something we built here specifically for heating small crucibles of colored glass. Is a small box of insulated bricks, backed by fiber, with a rolling lid. It has electric elements and is controlled by a small temperature controller.

[@vidhya..1234]

[@MrTonyFaith]

Does the sbruffo technique and stability to the bubble?

[@corningmuseumofglass]

Hi Tony, here's Bill's answer: Sbruffo-that, if you pronounce it properly, should draw a hearty “GESUNDHEIT!!!” from anyone nearby-indeed adds stability to the inflated glass. In the case of large reticello platters, such as those famous ones in Rosenborg Castle in Copenhagen (1708-9), if carried out on the inner/insert bubble (not the ‘cup’) leaves a ‘coating’ of clear glass on the top surface; it’s thus stronger and, perhaps, easier to clean. In the case of the three-bubble vessel illustrated in the email below, sbruffo simply makes the glassblowing easier-thicker is easier, in glassblowing-and it leaves the object a little less fragile. Know, however, that the spectacularly fine group of late-17th-early-18th-century goblets-again, like examples at Rosenborg-are made solely of canes: no sbruffo! Many are of the very highest craftsmanship and difficulty…AND rather thin for filigranna (they’re always a bit thicker than solely clear-glass objects, that can be absurdly thin!). My theory du jour: sbruffo is glassblowing-acrobatics with a net; non-sbruffo without…What do you think? Thanks so much for your question-and interest!

[@MrTonyFaith]

@@corningmuseumofglass Thank you, I'll have to try this sometime.

[@rajeshap7932]

suber.....

[@housevollmer9106]

Could boro be worked this way?

[@corningmuseumofglass]

Good question! We asked Eric Goldschmidt, properties of glass programs supervisor at the Museum, this question and here is his response: "These same types of patterns and forms can be and are made in borosilicate glass. However, it would be extremely difficult to work borosilicate through this same process to achieve the same goal as the soda-lime glass that Bill is using. Borosilicate has a much higher melting temperature, and it does not stay soft for nearly as long as the soda-lime glass being used in the video. Therefore, it requires hotter furnaces, additional torches for heating at the bench, and a much faster working time for the creation. This is why objects like this in borosilicate are more commonly crafted on a torch rather than at the furnace." Thanks for watching!

[@Tiberiotertio]

Beautiful glass, but I suppose glasses like that cost also a fortune?

[@Stormlaughter]

But how do the molten glass end up with pretty colors? Is it the heat?🤔🤔

[@corningmuseumofglass]

The metal oxides required to make different glass colors are added to the batch of the glass before it is melted. Thanks for watching!

[@TaurusPresents]

When the glass is hot then the whole glass object colors red or orange. After cooling down you can see the colors that are used for the glass object. I am addicted to hot glass and also have several glass blowing videos on my KZbin channel.

Actually, it's centrifugal force, not centripetal at 5:19

[@nomaad660]

Actually, it's centripetal, not centrifugal. Ask a physicist.

[@angelaphsiao]

It’s definitely not centrifugal force, considering that’s not a thing that exists

[@tonciivanisevic9704]

Nope. The second half is expanding i.e. moving away from the centre of rotation, not the other way around. Hence, centrifugal. "...the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) directed away from the axis of rotation that appears to act on all objects when viewed in a rotating frame of reference."

[@dlwatib]

Well thats the funny thing about glass, when its super hot it turns into basically a clay consistency almost. And you can literally just cut it with a pair of scissors and mold it like you would a clay pot or something, its pretty neat!

[@andrewl3787]

2:33 , no ventilation for that bubble trash?

[@corningmuseumofglass]

+Andrew L --Unlike some, Bill doesn't blow his bubble so thin they become airborne when he breaks them. If you look closely, the pieces break and fall right to the floor. in this case, no ventilation is required. Another clever way of avoiding airborne glass is to blow the bubble until it bursts inside the glory hole or furnace. It will instantly melt back on itself because of the heat - nothing to sweep up!

[@LovinLife-pv7op]

I've noticed from these videos that it seems to be a male dominated interest. Is that because of the weight involved?

[@corningmuseumofglass]

Glassblowing is more male than female oriented, but these days not by much. Traditionally the heat, weights, general discomfort and most importantly the fact that it was a factory job, discouraged females from taking part or playing a large role. Currently, there are many females involved in furnace glassblowing and they are becoming more represented as the years pass and their skills grow.
