Cold and clay

I am having some warping in the earthenware clay.  I am experimenting with some hand building clay but no distinctly different results yet.  I am starting to pack the big kiln but it is so cold drying is slow. I bring them into the central heating to give a good start

i am going to try  some midfire porcelain. Just because I can as a contrast to the thicker earthenware.

its cold here in Canberra.  Minus 4 in the morning makes the floor tiles icy.  I have bought a small cafe type heater. It helps. I can work in the afternoons. I often fire up the kiln to 100 degree so or make sure the pots are dry
