sethhoward said: ====================================================================== In a post about copper tuyers you mention using ceramic kiln supports. The only ones I can find online that have in ID large enough have an OD of 3". Can you send me a link or give me the name of the pottery supply shop where you buy yours?

They come in various lengths, I get the 12 inch ones. They are about 3/4 ID (2 cm), maybe about 1 3/4 OD.
I get them as a standard stock item from Pottery Supply House Canada :
They would do mail order off their web site.
m Round Shelf Supports, 1 3/4" Dia.
(Recommended for cone 10)
Part number FRP12 - 12" $6.50 ea (CDN)
I normally pick up my orders (powdered clay and iron oxides) directly from the Kitchener store. :
