In this round of testing I had a few aims. Firstly I wanted to pursue the yellow glaze. In my last round of tests I got some promising color responses but I had way too much flux so the tests ran a lot. See my last blog post for details. In this set I got some pretty promising yellows!

I also wanted to hone in on a tenmoku glaze. I was interested to see whether or not there would be a difference in using lime or wollastonite as the main flux in these glazes. I used 20% wollastonite compared to 16% lime. I had thought that lime was a stronger flux because wollastonite has silica in it too, but it turned out that the wollastonite tests did run a little more. This is not a scientific result as there was 4% more wollastonite. The difference in flux did impact the look of the glazes fairly considerably.

I also decided to do a line blend of my DP granite with salt, and also tin oxide, just to see what would happen. The salt was a disaster and the tin was okay but nothing to write home about!

Here’s the video…

In my next blog post I will lay out these tests in more detail with pictures and notes.
