It is low-fire, so that I could control the markings precisely, and I used Amaco's Superclear, a lead glaze, for the topcoat. I just thought I'd soon be in need of an urn myself if this piece were ruined by bubbly or cloudy glaze. One thing about those lead glazes: you can count on them. It's gonna be a perfectly clear, glassy surface. And it seems quite unlikely that it would ever be used for food.
I hope my customer likes it.
