multi-layer shelves

Post by sslickk »

HI,

Does anyone have any experience stacking shelves in the Evenheat "coffin"? I need to fire polish 15 pounds of 10 mm square thin bullseye pieces.

If I put a layer directly on the bottom (using fiber paper) and then a layer of kiln shelves above that, I figure I can get 4 cut up sheets in at a time. Or nearly.

Am I going to have a real uneven batch ie top layer will be more exposed to heat than bottom and thus "fired more" than the pieces on the bottom?

Thanks,
JC

I have stacked shelves in my Skutt coffin. You do have uneven heating occurring since most of the elements are in the lid. When I stack I use two shelves. The glass on the top shelf will full fuse while the glass on the second shelf will tack fuse. So I arrange my projects accordingly. How consistant do the pieces need to be?

HI,
Basically I just need to polish/eliminate sharp edges on little single layer pieces.

My usual single layer fire goes up to 1400 w/ a 5 minute soak.

I was thinking to use only the side element,, it would add heat up time but might give me a more even result. Only the ones nearest the edge would be "more" fired? This isn't real critical. They're pieces that are being used in silver jewelry.

I've got a contract with one of the Bali silver manufacturers.
