AMACO Potter's Choice PC-20 Blue Rutile Glaze, Pint
Highlights
- Fires to cone 5-6; apply to bisqueware fired to cone 04
- Pale blue where thick, brown where thin; very fluid, so it shows off texture
- Reduction-style effects from an oxidation firing; layers well with other Potter's Choice glazes
- ACMI AP seal (conforms to ASTM D-4236); AMACO rates it 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
Load a soft, natural-fiber fan brush and float each coat on; reload when the brush starts to drag.
- 3
Build up 3-4 coats, letting each coat dry completely before the next.
- 4
It's a very fluid glaze: fire a test tile on your clay first to see how far it moves.
- 5
Glaze fire to cone 5 (2167°F) or cone 6 (2232°F) at medium speed.
- 6
For layering, AMACO's guide uses 2 brushed coats of each Potter's Choice glaze.

About this glaze
Blue Rutile is one of AMACO's best-selling Potter's Choice glazes, and a lively one. It pools into a flowing pale blue where it sits thick and breaks to brown wherever it thins, so carved lines, stamps and throwing rings stand out. It fires at cone 5-6 and gives a reduction-style surface from an oxidation firing. AMACO rates it a very fluid glaze, so expect movement in the kiln; that movement is also what makes it so good for layering with other Potter's Choice colors. Brush it straight from the pint jar. It carries the ACMI AP seal and AMACO's Food Safe seal.
