I'm a stingy kinda guy at school.
When your supply budget for the entire art program is $0 for the year, ya
just gotta be creative.
I have a fund in our educational foundation for the ceramics program, can
but anything I need.
The rest of the art program will need to figure it out on their own.
When I ran kilns with Kilnsitters, I would reuse the small cone several
firings. Always fired with witness cones, never melted the little one in th=
e
holder. If it deformed a bit, I would just turn it over for the next firing=
.
It was one cone higher than the witness firing cone. If the guard witness
cone didn't deform, I often used that for a second firing. Never a problem
because I always fired with new target witness cone.
Now have new programmable kilns, bought with grant money.
Continue to ALWAYS use witness cones.
NEVER rely on the thermocouple.

Absolutely. I only use Pyrometers to tell me how fast I'm firing and how
well I've set the reduction in my gas Kiln.
My Electric Kiln has a very fancy and very good controller AND a Kiln
Sitter.
I only trust cones!
