self-supporting cones

Small cones would be more difficult to see through a peephole. I prefer the
Orton self-supporting large cones. The 8 degree slant is built into the
base, so they are fast to set up and offer consistent results. They are 36
cents each. Is it really worth your time to make clay plaques for the
standard cones?

Should I use the orton small cones (same as used in the sitter) in a wad of
clay, or large cones?

Nope, that's why I've been using Orton cone plaques/holders for a few years.
They are press molded refractory clay and come as dry greenware.
Each has three openings for large cones, with the bottom where the cone sits
at the correct angle.
Don't know if these are intended as "one use" or not, but we usually get a
dozen ^6 firings out of each. Coating the area of where the lowest
temperature cone sits and melts on also helps to extend the life of the
holder.

I did a web search for these, but can't find them. I've found the refractory
2 & 4 hole holders selling for 50 cents each.

I'll check the box at school and post back with name/catalog #.

Bill,
What do you coat the cone holders with?
Thanks, Gail in Ann Arbor

I purchased these cone holders a number of years ago. At that time I found
that the quality control was not very good as many cones did not fit
entirely into the holes and extended out the bottom to make the pat
unstable. The idea is very good, but I would not go back to that system
again unless I could count on them fitting properly. Don't like to bash a
product, but that is my opinion based on past practice.

If anyone has had good results recently, I would like to know.

Thanks,
