Had a great time glazing and firing some greenware with some new glazes and found probably one of my most favorite – temmoku! Oh it breaks just so perfectly and no pinholes on the white body. On red it is black with a complex mix of matte and shiny black spots. Just beautiful.
I tried some iron oxide colorant but that is finicky for me at least with the clay body I am currently using. A thick mix of iron oxide in a spray bottle seems to show some promise as long as you don’t let it run. The key is to get the droplets but not let them collect and pool. I think that a very thick application for drawing or accenting certain parts of the pot might be interesting but it didn’t turn out nearly as expected. I feel that it will be very specialized application only and that I’ll use it when I find the need.
Still getting some pinholing with certain glazes even with the tips mentioning a slower cooling period. I will try a soak for 30 minutes next time to see if that’s the ticket. I’m slowly but surely working out what glazes to use on what bodies to get the best effects. Firing journal is very helpful.
