- Using heat and gravity, art glass can be shaped over and/or into molds in a kiln to create an almost endless variety of forms. In this lesson you will learn about glass “slumping” methods, with a focus on using commercial ceramic molds.

Concise yet comprehensive. Thank you!
You're welcome!
this was really educational, thank you for putting in the time and work to explain this! i feel like i learned a lot
Thanks Liz, glad it was helpful!
This is a really informative and helpful tutorial, thank you. It clearly explains many things that I did not previously understand, for example the relative amounts of heat work required for different sizes and types of molds. The visual examples were a great help to understanding the concepts that are explained; for example, the viscosity of different types of glass and how these behaved differently in drop-out molds.
Glad it was helpful! There are plenty more here, on Vimeo, and at videos.bullseyeglass.com
Great information. I am starting to understand. Thank you.
Glad to hear it! You're welcome!
Great info., thanks.
Thank you brilliant video and has made things understandable to me that I didn’t know
Glad it helped!
Perfect indications. Thank You it is inspiring to try new ideas
Excellent to hear. Have fun experimenting!
Very helpful. Thank you
You're welcome!
this video is super helpful! i was curious at 0:12, i see a clear square tray that looks like bubbles in them. how did you do that?
Michelle,
Yes, that 'bubble grid' is a cool effect isn't it?
And, happily, it's super-simple to achieve:
You're simply full-fusing two pieces of reeded glass laid-up face-to-face with the patterns running perpendicular to each other. After fusing you'll see that each intersection of the lines crossing each other has captured a single bubble. That's it!
In the example here it's all clear but imagine if the bottom piece was black reeded or if the whole clear/clear assembly was fused atop another color? The bubbles will capture light and cast internal shadows in a way that creates a very powerful depth effect.
Thanks and good luck!
@@BullseyeGlass thank you for sharing, i'm absolutely in LOVE with this unique look! for the second idea with adding color, should the colored glass be transparent or opaque in order to see the shadows, or does it matter? thanks for the inspiration and sharing the knowledge, much love!!
Michelle,
You're very welcome!
As far as adding color under the clear/clear reeded assembly, having an opalescent with a medium value would probably read most dramatically as far as the shadows go.
Black underneath clear/clear is impressive too. Not that there are shadows but it makes the bubbles really pop (ha!) by contrast.
Thnx!
@@BullseyeGlass that's awesome -- i'm so excited to try this out! can't wait to make the bubbles pop 😆 thank you!
Can boron spray release be used on molds instead of kiln wash? How often does boron need to be washed or scraped off a bisque mold?
Najia,
We do recommend ZYP boron nitride spray release on our Colour de Verre casting molds. We have a link to download an application note PDF available at shop.bullseyeglass.com/zyp-boron-nitride-aerosol-lubricoat.html
As for further usage advice I recommend dropping in on our Facebook group at facebook.com/groups/BullseyeGlassCommunity/
Thanks!
I have stain glass that I got from studios going out of business and have no idea what types I have. Can I furs the glass and not use it for stain glass only. ?
Hi Mellisa,
A given glass can always fuse to itself. Beyond that it would require compatibility testing to see if it would work with other glasses.
At Bullseye we use a technique called a 'chip test' to continually monitor the compatibility of glasses as they are produced. You can learn more more about this in our publication 'TechNotes 3: Compatibility of Glasses'
www.bullseyeglass.com/methods-ideas/technotes-3-compatibility-of-glasses.html
The only materials you'd need to perform a simple version of this test would be some polarizing film. You could perform those chip tests between any glasses you'd want to combine and then go from there.
There is a good community of folks discussing glass projects at our Facebook group:

Thanks!
How do you know the glass you make or slump as a plate or bowl is food safe?
Kristy - With our glasses that contain more than 1.0% lead or more than 0.5% cadmium we recommend capping them with Bullseye clear glass for food-bearing objects.
We have more on food safety with lead and cadmium bearing glasses in this article:

@@BullseyeGlass thank you so much!! That is SUPER helpful 👌 I really appreciate you taking the time to respond!

How to make A mould please show us
I don't know what we have with our free TH-cam videos but we have a lot of mold related content in our subscription library: videos.bullseyeglass.com/?s=mold
