I am fascinated to find this thread because I've also been working on using a laser to etch glass lately and haven't been able to find much on other people doing it (I may just be looking badly). I currently use Titanium Dioxide which comes in a powdered form and I mix it with water and glue then pa...

Hey everyone! I fired these pattern bars earlier this week.

And I know I cut the fiber paper badly. The glass is all Oce...

Thank you! That is interesting. I'm using pre-made frit but I'm working in an oldish kiln that is used by many people. Do you think it is it possible that something is falling out of the kiln lid and causing these spots?

I've been fusing glass for about a year using kilns at a makerspace. Sometimes when stuff comes out after a full fuse, they have little marks on them, usually like black dots. The spots are usually smooth and feel the same as the rest of the piece. PXL_20250903_185334054~2.jpg PXL_20250903_185334054...

Thank you so much! I really appreciate the feedback. I think that I'm just going to slump it bubble up and have a small bump at the bottom of the bowl rather than continuing to try and fix it (unless that's a super ill-advised idea for some reason). If I was trying to fix it though, you're saying pu...

I refired my second piece and ended up with a small bubble going the other direction and was wondering if anyone had any feedback. I put it in the kiln bubble-side down. I fired with a piece of fiber paper underneath and kiln paper on top of that because I was trying to be extra cautious about bubbl...

I will definitely be consulting the books for figuring out firing schedules in the future!

Thanks so much for your help!

Also, when I refire, I was thinking of putting fiber paper on the bottomto help with airflow around the piece. Can I put kiln paper (I have Bullseye Thinfire) on top of the fiber paper to try and mitigate the rough texture or would that defeat the purpose of the fiber paper? Is fiber paper something...

Great! Thank you for the advice! If I want the glass smoother, rather than more like a task fuse, how long do you recommend holding it at the top temp? Or is that more a matter of what the top temp is? Yeah, I'm definitely finding that some people have bad schedules but hopefully I won't lose my rec...

Schedule: 1. 300 to 500 for 30 2. 400 to 900 for 15 3. AFAP to 1425 for 30 4. AFAP to 930 for 40 5. 200 to 700, no hold then cool to room temp. I figured that I brought it up too quickly; my iPad died and none of my notes from previous firings were backed up, so I was just using a schedule suggested...

I've been working on this bowl and got a huge bubble when trying to full fused some frit on it. I was hoping to slump it into this bowl mold.
