Sometimes, when it doesn't count, when there's no pressure, when it's "Let's just see what happens"....... wonderful things can happen.
That's just what happened with this little trivet.
I was busy teaching myself how to throw an upside-down trivet.
I made essentially a bowl with an exaggerated bottom that was thicker than usual. I extended bottom rim and brought up the sides and turned the top edge outward, making a convex shape.
I let it sit on the batt until it was dry enough to take off. I turned it over, trimmed the (now) top to recess the surface and create a slightly higher rolled edge.
Then I cut into the sides of the bowl to make 4 feet, rolled worms to support them and let the whole thing dry.
It warped slightly during the bisque firing, but I kept it for a test piece anyway.
I dipped it in white glaze, dipped a big brush into watered down cobalt stain and just let the brush dance. I was thinking Sandy Brown. http://www.sandybrownarts.com/sandybrownarts.htm
During the firing, the stain went nuts. It popped all over the place making a lightly dotted patterns all over the white glaze.
Give a piece strong enough legs so it won't warp in the bisque firing.
Don't use straight cobalt stain.
It's possible to throw a trivet upside down with little trimming and alteration.
Big brushes and a fast and loose application makes a piece that comes alive.
