About this glaze
HF-9 Zinc-Free Clear is AMACO's glossy, transparent clear for covering underglaze work at mid-fire. Zinc can pull some colors, chromium greens in particular, toward brown, so this clear is made without it; most underglazes, stains and oxides keep their truest color under it. It belongs to AMACO's High Fire (HF) line, fires at cone 5-6 and, per AMACO, up to cone 10, and can be fired in oxidation or reduction. A few underglazes may look muted under it: V-315 Peach, V-316 Light Pink and V-323 Salmon. Brush it straight from the pint jar. It carries the ACMI AP seal and AMACO's Food Safe seal, and AMACO lists its clears as lead-free.
