Refires are the BEST...but only when they come out like this!....which isn't a gaurantee. Far from it, actually. This 4.5" tall stoneware mug got some wild ash and soda flashing. I'm not even sure where the color came from, but it has some pink highlighting with smokey blues and grays. Wild stuff here, folks. I'd say it's a safe 10-12oz'er.
