Pottery: Making Drink Coasters Part 2 - Melting Glass

[@____Ann____]

Wow. It made a snowflake crackle.. Beautiful!

[@maciejsimm2342]

i've done glass coasters many times but Ive never seen the egg-shell like crystals like in yours. I think pre-firing / pre-shrinking is a great idea, I'll have to play with this :) thanks for the tutorial

[@LockStoppageSandwich]

They’re GORGEOUS

[@EvolutionStoneware]

Thank you! ☺❤

[@knightclan4]

Great work

[@EvolutionStoneware]

Thank you!

Hi I just found your channel. I love your clay coasters. I design coasters made from wood and fabricated ceramic tiles. However, I would love to make my own coasters. Love the glass look. I'm currently taking pottery classes and will ask my teacher about this process. Thank you for sharing your passion and design s. Hellena

Great to see you again. Love these. That glass is so pretty!

[@evanstephensceramics]

Janis always makes awesome and super helpful videos! The coaster look great!

[@EvolutionStoneware]

Thank you Evan! ❤ you, my friend!

[@natalielobo]

Beautiful!!

[@EvolutionStoneware]

Thank you so much Natalie! I have more in the kiln right now. :) Hopefully they turn out as lovely as these did.

[@manateepottery]

Lovely! And thanks for the tips, cut gloves would be such a useful thing to have on hand in the studio!

[@LilitaLanger]

I may get feedback on what temperature it was in the kiln at and how long

[@ThatOldBiddy]

very beautiful

Love these, may reuse your idea, if that's ok with you . Thankyou

[@EvolutionStoneware]

Totally! Go for it.

Hello!! I JUST found your channel and am so inspired by your technique. I am a ceramic "artist" (I use that term lightly) and have a ton of glass that I always wanted to incorporate in my ceramics. My question is that you say you bisque to 04 and then use a clear glaze on the inside and then fire to cone 6 (2232o) is that correct? I thought glass can only be fired to max 1500o I LOVE your pieces! and really would look forward to you confirming cone 6 for ceramic/glaze/glass firings! TIA your items are OUTSTANDING!

[@EvolutionStoneware]

I fired the clay directly to cone 6 with no bisque to get all the shrinkage out of the clay. Then I applied clear glaze while they were hot, and then added glass. Then I refired to cone 6. I used COE90 Frit for the glass. I hope that helps!

[@irper1042]

C'est fantastique !!!!❤

[@ipekusta]

Hello, very nice tutorial :) Thank you! What is the cone that you are using for the bisq fire?

[@marciasilviajohnson6461]

Beautiful I love it I going to try

[@007HANDMAN]

Great tutorial. Have you tried to put colored seed glass beads any time like a mosaic?

[@EvolutionStoneware]

Hi Robert! Thank you! The only other glass I've melted into coasters is the marble-like decorative glass beads that are flat on one side or a little oblong. I used blue, white, & clear pieces together, they didn't spread as evenly as the glass frit I used in this demo and bubbled more. The results left me disappointed. You might have better luck, though. There are so many variables.

[@troyaparish]

Great results, thank you for sharing your process! I've found that doing a "soak" or hold time (7 minutes) or so minimizes bubbling. (I bisque fire at cone 04 and add glaze and glass on; firing to cone 5) In addition to your "medium" firing do you program a soak/hold?

[@EvolutionStoneware]

Hi Troy, thank you so much for that info! I didn't do a soak on this firing. For normal glaze firings in this kiln I do a 10 minute soak because it's necessary for it to reach a proper cone 6. If I do more glass like this I'll try soaking it for the bubbles. Thank you again! That's very helpful.

[@leahengel2790]

hi! do you think it’s ok to use glass in an ash tray? is it safe enough to be able to stamp out the joint on the glass and then use the joint another day? is ok to wash the ash tray?

[@EvolutionStoneware]

I think it would be fine, but I don't know for sure. In this case to minimize any slivers of glass popping up I recommend high firing the clay first to get all the shrinkage out then refiring with the glass inside (as I did in this video). Also cool the kiln very slowly when the glass is inside. Good luck! I hope it turns out awesome!

[@connecticutaggie]

Can you explain why glass melts are Cone 6? From the Orton tables, I Cone 6 is about 1220C; but, the melting temperature of glass is listed at 1400-1600C.

[@EvolutionStoneware]

Honestly I don't know. Perhaps someone else on here is an expert on heat work on glass & can provide an explanation.
