The Nuka glaze I made has a very simple recipe:
- 1/3 washed wood ash
- 1/3 Kona F4 feldspar
- 1/3 silica
It is pretty thick and gloppy, because I didn't want to put my ash through a fine sieve - I like irregular, splotchy, runny glazes that are interesting to look at! But the interesting thing is that it goes onto the bisqueware really thick - like 1/8" or more. Thankfully it doesn't run too much, so you can get away with this.
Here are the test tiles I made with the Nuka glaze. These are pure Nuka on B-Mix and Dark Brown test tiles:
The glaze is very rough and craggy, and very matte. Curiously, the glaze seems to break black on the sharp edges on the B-Mix tile.
Nuka and Tenmoku are a classic combination, and this glaze certainly didn't disappoint in that arena!
This is much more what I wanted - a nice, runny, creamy white glaze. It seems that the tenmoku is just enough to flux the nuka and create a wonderful combination. The brown flecks in the glaze are just fantastic.
Once I saw these results, I tried the nuka glaze on a couple of cups I made, over tenmoku, of course. Here are a few more pictures of the best one.
Of course, I will have to keep refining these glazes, but this was a result worth sharing!
