Polar Ice Cone 6 is Here!

These are two cone 6 transparent glazed porcelain mugs with a light bulb inside. On the left is standard clay porcelain body, right is the new Plainsman Polar Ice. This has it all: Super whiteness, translucency, good drying, stability in the kiln, easy glaze fit and fantastic plasticity! No clay we have ever made even comes close to what this can do! Our new base and liner glazes also fit it well. Click here to learn more.

Revised Sculpture Body

It is significantly cheaper and a lot better than before. The plasticity is still great and it is still made from a very vitreous dark brown burning base with 25% added coarse light colored grog. But the fired surface is even more interesting: soluble salts gloss and variegate it and small iron eruptions adorn the clay gaps between grog particles. Click here to learn more.

Ravenscrag Slip and Alberta Slip

You will not believe the range of glazes you can make from these materials! At both cone 10 and 6. Each of these special materials has its own website with everything you need to know. Please visit and

Cone 6 Prepared Base/Liner Glazes

We are making base glazes for all major clays bodies, starting with cone 6. There is even a cone 6 magnesia matte that feels like a cone 10R dolomite matte! You will be able to buy these in bags, just mix with water, screen and you have a base transparent that will be hard, resistant to leaching and crazing and easy-to-apply and use. Want the recipe also? No problem - the recipes are available and very well documented.
