Zinc crawl glaze
This glaze transforms into beads. When applied thickly the beads become bigger and escapes to larger gaps.
Top: glaze base, no colorant.
Bottom: adding chrome oxide to zinc creates a pale pink color.
Test tile firing 1220-1240 C.
Adding copper oxide creates hues of green depending on the amount. Copper also makes the glaze consistency thicker compared to above white and pink versions.
