Slip

I've been messing around with some slip.

This is using some recycled clay for the pot (thrown off the hump!). It has quite a bit of terracotta in it. I find the orange a little much, so I was trying to create a layered feel by brushing on white slip whilst it was still on the wheel.

Then I added some black slip to the top after they'd dried a little.



The slip recipe...
Calcium Borate - 30
Postach Feldspar - 30
Ball Clay - 25
Silica - 15

For the white I've just added some porcelain slip I had from throwing, to thicken it up and give it some density. For the Black, I've added a good portion of Ebony underglaze powder.

Then I'll give them a clear glaze. Not sure whether to take this clay up to Stoneware or just to Earthenware... could be risky given the amount of terracotta
