Amaco Potters Choice Lead-Free Glaze PC-59 Deep FireBrick - Rich Cone

In this review we look at the Amaco Potters Choice PC-59 Deep FireBrick glaze and why it has become a go-to for potters wanting authentic reduction-style color from an electric kiln. The bottom line: this 1 pint jar delivers a deep, glossy red that reproduces many of the warm, variegated effects of higher-temperature reduction firing while staying accessible and safe. It is best for ceramicists who want reliable color, easy mixability with other glazes, and a lead-free option that can be fired to cone 04 bisque and used at cone 6 for excellent results.

Key Features

• Lead-free formula: Provides a non-toxic finish suitable for studio work and hobby pottery without compromising on depth of color.
• Cone 04 bisque firing: Can be applied and fired from a typical bisque base, making it convenient to integrate into existing workflows.
• Cone 6 appearance: Recreates the look of cone 10 reduction glazes in an electric kiln at lower temperatures, saving time and energy.
• Mixability: Blends well with other Amaco glazes to create layered or custom effects, giving more creative control over the final surface.
• Rich deep red color: Produces a glossy Deep FireBrick finish that stands out on functional ware and decorative pieces.

Who It's For

This glaze is aimed at hobbyists and intermediate potters who want the appearance of reduction firing without investing in a gas kiln or pushing to extremely high temperatures. It suits makers who value a vivid, glossy red and who like to experiment with layering glazes for varied surfaces.

It is less appropriate for those who require very large coverage quantities for production runs, since this listing is for a 1 pint jar, or for potters seeking completely matte or very subtle pastel surfaces where a glossy, strong red is not desired.

Pros & Cons

Cons

• Available in a 1 pint jar which may be small for large or commercial projects.
• Sturdiness of the final look received mixed comments, so results may vary by application and firing conditions.
