Striking Colors at the Torch with Stephen Brucker, Summer 2021 Studio Live Stream

[@jannapackard3910]

Excellent explanation of the types of flames and how to recognize them. Beautiful work. Thank you.

[@corningmuseumofglass]

Thank you for watching!

[@StricklersGlass]

Absolutely beautiful piece 😊 thanks so much for this video, learned so much 🙏🙏

[@mrzoso4940]

I have been trying to get better control of my color striking abilities. With this new knowledge I hope I can finally get full control over my flame palette. Thanks Corning! I think the Corning demos are the best ASMR or ghostly shipmates for those in hanging solo in their studio.

[@mikec3820]

great demo. and my 3 fav colors too lol

[@MAGATRON-DESTROY]

Flame chemistry doesn't effect striking, it only effects surface silver. Heat is what strikes glass. It's sad because this dude is working for corning. Glass Alchemy has some very good reading on this topic that will give you a much better understanding of this situation 👍

[@fairwitness7473]

This is exactly what I needed...!

[@corningmuseumofglass]

That's great! Be sure to check out the other flameworking demos on our channel for even more kzbin.info/aero/PLx9b2TiEudYcZ0c8onXdulY8T_Rto37sg

[@michaelcolton9530]

What about when working with silver potion or ectoplasm from glass alchemy? Im trying to keep the glass transparent and have the silver fume lines show, sometimes it will do what I’m trying to get it to do and show up on a bit of a piece but not fully it will only be on some parts. Any tips? I have pictures of what I’m trying to get if that would help. But can’t seem to figure out what I’m doing wrong no matter how many videos I watch or how much I google

[@bobbyjunior8579]

Hey I had some mai tai that went clear and I cannot get it to change back to the nice colours it produces, wish it was that I accidentally used clear but not the case.

[@baddonkey75]

Mvr works i work in a high oxy flame and hope to flame strike at the end and in the kiln

[@jonnyg7629]

NICE!! how do i catch this live??

Hi 👋 I have been trying to stike amber purple fine frit that is incased in a 32mm extra heavy wall blank. I always seem to get a brown or red color. I can strike amber purple with a regular rod and get purples, But with the frit incased it seems impossible! Please 🙏 help this is so frustrating 😢 if any one has any suggestions it would be much appreciated 😊

[@corningmuseumofglass]

Hi👋 From Eric Goldschmidt our Supervisor of Flameworking and Properties of Glass: It is very difficult to get fine frit to strike as well as thicker grades of frit or rod. It is also difficult to get amber purple to strike when it has been deeply encased. I would suggest using a larger frit size and a thinner-walled tube. Additionally, it is really hard to get encased amber purple to kiln-strike. I suggest striking it with the flame for best results. Hope this helps!

[@thomasrobinson6495]

hi thanks for the videos. Is the technique the same when fuming with silver and gold?

[@corningmuseumofglass]

Great question! Stephen says: “To answer the fuming vs. striking question, no, they are not the same process at all. Fuming is an a external surface application of vaporizing metals (most often gold and silver, sometimes copper but it's fairly toxic) onto the glass. Striking is an internal process achieved by heating the glass composition in a highly oxidized flame to break and suspend the crystalline structure of silver metals within the glass. As the glass cools the silver crystalline structures will reform but if they are introduced into a reduction flame (low oxygen) after cooling for 20 seconds, the crystalline structure will realign to produce a spectrum of colors. The length of time that the glass is held in the reduction flame after cooling determines the color that can be achieved. The time/color spectrum from least to most amount of time in the reduction flame occurs as follows. Transparent, yellow, orange, red, red purple, purple, blue, and finally green. I hope this information is both helpful and useful.” Thanks for asking and watching this demo!

[@airforcerob]

@@corningmuseumofglass I"m looking for a demo or more precise information on how to achieve different colors from fuming silver. I've read there are many different colors to be achieved but I can't find the information in one place. I tried fuming and then using the above technique to try striking, but haven't had any luck so far. Any suggestions or recs for sources?

[@johnprice2119]

From personal experience every distributor that carries Northstar colours typically has blue caramel available. I don’t believe it’s difficult to acquire.

[@joealphonse6604]

I was about to comment the same thing, MGA has blue caramel in stock at the moment.

[@johnnewton1051]

I have a lb of blue caramel and perked up when he first pulled it out and even more so when he said it was hard to get lol

[@corningmuseumofglass]

Haha that's great! Thanks for watching, hope you enjoyed this demo.

[@johnnewton1051]

@@corningmuseumofglass I did! Stephen did an awesome job and I learned a ton. Thank you all for putting out this type of video for everyone.

[@johnprice2119]

Interesting I’ve never had difficulty finding blue caramel for sale😂

[@skeetlejuice522]

I'm not trying to be rude but you didn't really specify in the beginning of this video actually what's happening here like why is the glass changing color why wouldn't you just buy colored glass I'm confused is this the production of color like what's going on

Riiight

[@clintstenger1626]

Silver does not form crystals in borosilicate glass they are metalic nanospheres . Jesse Kohl did extensive research into the amberpurple color familiy particularly no crystals .. its bad terminology that leads to misconceptions about the processes at play.

[@clintstenger1626]

I put a link to the article in the flow Jesse wrote that states he looked and found no silver crystal growth in amber purple. And someone deleted it. ( corning ? )

[@MAGATRON-DESTROY]

​@@clintstenger1626this dude has no idea what's really happening, I tried to tell him striking has nothing to do with flame chemistry and everything to do with heat. Surface colors are but not exactly how he said. The worst part is this is corning and they are supposed to know stuff

[@clintstenger1626]

​@@MAGATRON-DESTROY redox (flame chemistry) does have some effect on striking as well as heat. In my understanding. What doesn't happen is crystal formation

[@fooooo8168]

I cant watch a demonstration video that mask is way too distracting.

[@lindacondray7918]

Shouldn’t be distracting. You’re supposed to be watching the glass work, not his face. Audio is good too.

[@michaelkmiec5842]

I agree Covid was so wack seeing someone blow glass with a mask on like that is so nutty.

[@MAGATRON-DESTROY]

​@@lindacondray7918it's distracting because covid is a joke, it's just a bad cold. Plus this dude doesn't know what he's talking about

[@kerryleinhard8335]

Ni fait ni a faire, rarement vu une démo de verrerie au chalumeau aussi lamentable ....
