Recent Work with "Crackle" Bead Glaze

When John Britt came and taught a glaze workshop at the Folk Art Guild in 2013, we mixed and tested many different glazes in a high fire reduction gas atmosphere. We tried to switch and vary ingredients in old favorite glazes that were not turning out anymore, and we also mixed new test batches of glazes looking for new surfaces, colors, and textures. One test tile we pulled out of the kiln and were very intrigued by was this bead or lichen glaze, that we have come to know as "crackle." It is actually a very simple glaze applied on bisqued and slipped pots, which separates from itself during the firing forming beads of glaze. I have been working with this glaze since then, and here are some pots from our most recent firing.
