Technical Question, Compatibility & School Projects

Mali C. bring this question:

Hello Jodi:

I took a visit to your site after viewing you on HGTV That’s Clever. Which by the way you did a nice job and I hope you were eventually able to view it if you haven’t already.

I work with elementary school children doing art classes as a guest artist. Most of the material I use is recycled, or things I donate. I have done quite a few fused glass projects, but donating these supplies (purchased 90 COE fusing glass) is becoming quite costly for me. I am looking into using recycled found glass to use with my elementary kids. I was given a case of wine bottles from a winery, all different colors. I was hoping to use the different colored glass (combined) on one piece. Kinda like how you crushed the red glass onto the one example you showed on your site. My question #1 is: are all bottles the same COE, (like wine bottles)? Question #2: Is all regular, float window glass the same COE, or do you just use all the glass from one window in each piece and not mix from other windows? Question #3: Do you experience a lot of devit on your recycled glass pieces? I actually like the look of devit at times and have seen some nice jewelry made from recycled milk bottles that had devit and they were wonderful.

Technical Question, Compatibility and Temperatures

This question was originally posed by Susan G.:

I enjoy your website. I am a beginner with fused glass. I was very excited to find someone who uses reclycled window glass and bottle glass ro work with.

Can you tell me:
1. the maximum temp to fire window glass and bottle glass
2. can window glass and bottle glass be fired together to make one piece?

thank you
Susan

Hi Susan;

The maximum temperature ranges from between 1375 for a slump to 1590 for a cast piece. The holding time varies as well, based on what you want to do. Different thickness and age of window glass all play a part. Different colored bottles melt differently as well. Generally I have found that newer windows melt more smoothly, and the darker the bottle glass, the lower the melting point. Continue reading Technical Question, Compatibility and Temperatures
