Potcalys buff stoneware which is a good throwing clay, which I fire to 1240. Stoneware is good for large
pots and anything in the kitchen. It is microwave, oven, dishwasher and waterproof (which is not the case with earthenware).
I often joke that it is also rust proof, but not teenager proof.
There are about 10 stoneware glazes, both shiny and eggshell finish. One glaze that I use alot is my "snowflake blue"
which is a dark blue glaze with flecks of white in it. It took 8 years to develope this glaze.
This jug has snowflake blue on the outside and MG23 on the inside.
MG23 is a glaze made up from the collected glaze from the filter in the spray booth,
and is therefore a mixture of all the glazes used in the pottery (both stoneware and porcelain).
Each year I make up a new batch (this one was made up in 2023), test it, and if its a satifactory dark blue shiny glaze,
use it on the insides of pots where it just has to be functional. It is also used to highlight my makers mark on the bottom of pots
I often use red and orange glazes from Botz as a decorative feature on the outside of jugs and mugs
