Glazing Part 2
Monday, January 14, 2013
End of Semester 1
Bone Dry - Clay that is completely dried but not yet fired. Clay forms are most fragile at this stage.
Leather Hard - Clay which has dried sufficiently to be stiff, but is still damp enough to be joined to other pieces.
It is important to trim pottery and connect slab work when the clay is leather hard because clay is too soft when you first make the piece and it could tear. When the clay is too hard it can break and chip if you try to trim it. When it is leather hard, however, it is the right consistency and will be easy to trim.
I have one more cup that has is being fired now which i still need to glaze. I also just glazed a piece that shows contrast in texture.
