Hi all,

 

I am fairly new to pottery but wanted to try throwing different clay bodies in various difficulties. One thing that really fascinated me are high grog content clays. The coarser the better. I came across this moon jar that I wanted to attempt but wasn't sure how I could come up with it. The artist said it is a mixture of porcelain and abereiddi stone + white jun glaze. Can someone advice on how I can get this clay body?

Any help is greatly appreciated.

 

Many thanks,

Jason

 

Porcelain is porcelain.  The key is his addition of a local stone -- abereiddi -- which he wedges into the porcelain and then fires.  The stone is likely a high iron content stone, so it shows through the white jun glaze.  Basically, he adds the local stone to his clay.  Whether he mixes his own porcelain or buys a commercial porcelain -- unknown.  But he adds the stone.  Likely fired to cone 10 or hire to get the stone to melt properly.
