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?

These are cylindrical supports intended for porclein kilns. Rated to something like 1150 or 1200 C.
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.
