...yes! I made a few of these just for that reason, as blank canvases for my next saggar....
...here ya go kids,
well you get the idea...
How tall are those and how much clay did you use?
This one is about 14-15", but thin-ish walls and a heavy-ish bottom.
I'm challenged, I admit it. It takes me a good 20 minutes to pull maybe 10-12 pounds of clay which is my limit.
Younger and stronger potters would pull that amount more like 18".
