I have two mugs with sand with effekt (glaze 42008 from Silicanordic) on the inside and nephrite green (glaze 42312 from Silicanordic) on the outside. I was not satisfied with the inner glaze, and gave the mugs a round of effect generator on the inside, but nothing at the outside. I refired one of the two mugs, but 10 degrees lower than the first firing ( first 1240, second 1230) What a change in the expression of the glaze on the outside!
Ther was no room for the second mug in this firing, so now I’m exited to see, if it will change the character of the outer glaze like the first mug. I have to wait at coupple of weeks!
two mugs after the first firing at 1240 degrees.
After refiring at 1230 degrees.
