AMACO Potter's Choice PC-42 Seaweed Glaze, Pint
Highlights
- Fires to cone 5-6; apply to bisqueware fired to cone 04
- Deep green that breaks brownish over texture
- Fluid, and more so when thick: control thickness so it stays off the kiln shelf
- Layers well with other Potter's Choice glazes
- ACMI CL seal (conforms to ASTM D-4236): ages 13 and up, follow label cautions; not for spray application
- AMACO Food Safe seal: tested for lead and cadmium release per ASTM C738-94
How to apply it
- 1
Start with clean bisqueware fired to cone 04.
- 2
Brush on with a soft, natural-fiber fan brush, floating each coat on. This is a CL glaze, so don't spray it.
- 3
Build up 3-4 coats, letting each coat dry completely before the next.
- 4
Watch the thickness: Seaweed gets more fluid the heavier it goes on, and AMACO warns it can flow onto kiln shelves.
- 5
Fire a test tile on your own clay before glazing a finished piece.
- 6
Glaze fire to cone 5 (2167°F) or cone 6 (2232°F) at medium speed.
- 7
For layering, AMACO's guide uses 2 brushed coats of each Potter's Choice glaze.

About this glaze
Seaweed is a deep, fluid green that breaks toward brown over texture and runs more freely the thicker it goes on. It pairs well with many other Potter's Choice glazes in layers. AMACO's own advice is to watch your application thickness so the glaze doesn't flow onto the kiln shelf, so test it on your clay before a big piece. Fire to cone 5-6. Brush it straight from the pint jar. Seaweed carries the ACMI CL (Caution Label) seal, for ages 13 and up and not for spray application, and it has AMACO's Food Safe seal.
