So those mugs I talked about the other day which were getting ready for their biscuit firing in the kiln. Well they’ve been fired and the next stage is glazing.
I’m going to pretend that you know literally nothing about ceramics when talking about glazes.
When a pot is biscuit fired in the kiln it means that it becomes heated to 1000 degrees. This removes all the water from the body of the pot making it very porous.
