Good to see you changed your username, Paul. As a Teware Artisan... it makes sense
FYI... I have finally located a source of consistent large volume rice husk ash here in the States. I am working on testing now. It is looking like it will undfortunately have to be ball milled before use. I have a ball mill... so for me that is no issue, but for others.... maybe it would be. Then I am going to try to get one of the ceramic suppliers (likely Sheffield) to regularly stock it...... so that I don't have to buy it by pallets.
Nothing beats the "real thing".... I put my synthetic nuka right beside the real one I use (Hamada Shoji's actual recipe),...... and there is no comparison. Natural meterial glazes are the most complex and subtle chemistry due to impurities and particl size distribution, and that gives the darn glazes such a rich appearance.
Up til now, I've been importing RHA from Asia... and it is ABSURDLY expensive to do so..... the material itself is cheap... the shipping is KILLER.
Looks like it was a nice firing. Someday I need to stop over when you are firing to get a "look see".
