How thick should a slab of plaster be for Wedging


Recommended Posts

1# Pottery plaster is much better than POP-that you will find is to soft.I would cast it 4-5 inches thick.You can also use casting plaster sold at a building supply-just make it 5 inch thick.Mine is 45 years old out old casting plaster and 5 inch thick.

I should mention I always ove kill just about everything

Filled an Amaco wedging table years in the past, 3 inch side board with double wire cutters mounted to side and center posts. Lasted for 20 years when we refilled it. posts were the only area where plaster cracked as they got knocked from student abuse. I would say 3" is nominal with a good base.

 

best,

Pres
