Sometimes, it's good to slosh glaze.
Here's a stoneware bowl, reduction fired, that I made during a class.
I was in the class because at the time I didn't have my home studio set up then.
Thankfully, the instructor excused me from most of the participation and just let me work.
Using glazes I was totally unfamiliar with and had no clue how they would turn out, I decided to do the "Ink Blot" approach and put a base glaze on, then slosh a contrasting one over the top, rotating the bowl to make it run in interesting patterns.
I think the purple glaze was called "Fish Guts" or something.
Not for the faint of heart.
