Lots of stuff in this load. I wanted to make a bunch of lint feeders so I have a good supply. Lower left are the shakers I made. They were featured in this month's PMI - I really like them and loved making them!
I did some glaze testing on them, and got some good and some ugly results.
The firing was to cone 11, fairly heavy reduction.
First one I tried, which I thought would be a nice white glaze for my palette was a simple Shino from Lasse Ostman.
Also from Mr Ostman's site was a Green Matte Crackle.
Lastly was Hamada Rust from John Brit's website.
Not a one turned out as expected. I also experimented with applying a white slip over my dark clay body to brighten some of the glazes. That works well!
Lasse Ostman's Green Matte Crackle didn't turn out at all as I had hoped, I am really liking this glaze! Its pale minty green, flashed with pinky-gray, silky and just begs to be touched. It needs to go on a white clay body (this is Laguna 1/2 stoneware/1/2 porcelain ) and may do something different in oxidation, but I don't do much ox firing. Its definitely a keeper!
However, my attempt at Lasse Ostman's simple 3/3/3 Shino has some obvious issues.
It should have been a speckled white that breaks nicely. Instead its a greenish semi-matte without much character. Just not anything I can see using. As suggested, I applied it to my dark clay body.
Its greener than showing here BTW...
Hamada Rust on John's page and in his book that I wanted to try it. His examples are a deep smooth black breaking to rust. Simple, rich and classic.
I tried this on both white and dark clay bodies, with similar ugly results.
I want something opaque, something that breaks nicely and something very dark.
Perhaps some of my fellow potters can offer some insight.
I wish glazing was not such a struggle for me.
