Hi Patty, Please don't think I am trying to start an argument or anything. Far from it. I just want to show a different perspective. Before I knew that you were talking about fusing ashes in your pieces, I looked at your bowls section..... I could have very well asked the same 'copying' question of...

I looked at both web pages and did not find anything that would protect from copying either product. I agree that the products are very similar and certainly one could be a copy of the other. It is impossible to determine whom had the product first from the information presented on the websites othe...

When I was younger we use to do a neat trick of boiling water in a paper cup over an open camp fire. I believe the same principle is at play when you only boil water. The glass will not heat up significantly as long as there is water in contact with the glass surface. If you place food into the bowl...

Brock,

That's all I can think "black halo" would be, but you never know.

When I have taught young children to fuse I start out small with a magnet. Short attention spans and the need for instant gratification. If they want to learn more I have them do a picture frame with random scrap pieces. Some of the kids have progressed to bowls and fused panels for stain glass lamp...

Can you give more information on the black halo?

If you like the bowl a lot, I would not recommend putting it in the microwave for anything.

With only a tack fuse Marty is right you may just get away with an incompatibility. Try sticking it in the freezer and see if will handle the temperature extreme. This works at full fuse too when you are looking for residual stress in opaque glass.

I spent the morning looking through my reference books for Information I found on cutting with lubricants (oil). Unfortunately, I was unable to find the information. What I do remember is the lubricant provided a small amount of surface tension to the score on the glass. The science behind it was th...

I run my cutters dry most of the time. If I need to make exact cuts I fill the cutter with distilled water. I had to modify the felt a little bit to get the right flow of water, but seem to work just fine. On large circles for some opaque glass I spray the surface with distilled water to make cuttin...

Patty,

If you use US pennies they need to be dated before 1982. After 1982 the penny composition was changed to a copper plated zinc blank. The zinc will make a mess when it melts.

Re: question about fusing

Thanks so much for all the input. I hadn't thought about Nichrome wire. Do most other metals show oxidation at high temps? I was hoping for a copper 'finish' or shine but will try anything. Is there an easy way to find the melting point of different metals @ varying thicknesses? Fine silver, gold, ...

I have no doubt that what you want to do is possible. I have seen many things made that I would have said were not possible by some of the artists on this board. I don’t think I have ever seen what you are looking to accomplish. Start small and scale things up. Bending the stringers or noodles may...

I will sit out on the public critique process, as I do not believe that photos and a narrative will do a piece being croqueted justice. I need to touch and inspect a piece closely while asking more in depth questions of the artist. For me this process is best handled in person. I am sure other can d...

Lydia, You can slump that back flat. It might has shrunk some but probally not. Question... is what you are calling a crack really a crack or an air bubble? Going to full fuse temp will not get rid of it, if it is an air bubble. If it is a crack, which I doubt that looking in a kiln for a moment wo...

It sounds more like insufficient annealing time. To be safe the annealing needs to be based on the thickest portion of the piece. When you refuse the piece, go as slow as possible as you ramp up. There is likely still stress in the piece that has not been relieved. Don’t be surprised if the crack ...

If the kiln in question is used for production of your own work, you need to take into account the lost potential revenue it would have generated. At a minimum the fee should cover the power, labor, rental or mortgage, and insurance costs. Anything less than this is good will on your part.
