Speedball Underglaze Sampler Pack (12) 2-Ounce - Versatile Color Set

Our review of the Speedball Underglaze Sampler Pack finds it best for ceramicists who need a compact, reliable range of colors for surface decoration; the single biggest reason to buy is consistency - the opaque underglazes hold their pigment during application and firing, making them useful for detailed painting and sgraffito work. This 2020 assortment of twelve 2-ounce jars is a practical way to test new shades and techniques without committing to full-size containers, and the claim of a wide firing range and lead free formulation makes it appropriate for studio dinnerware when used with a covering glaze.

Key Features

• Trusted formulation: The sampler uses a professional-grade recipe that ceramic artists rely on for detailed painting and mishima decoration.
• Opaque coverage: Colors are formulated to stay put and not bleed, giving consistent results especially when two to three liberal coats are applied.
• Wide firing range: Designed to perform between Cone 06 and Cone 6 and reported to work up to Cone 10, offering flexibility across kilns and glazes.
• Lead free: The underglazes are dinnerware safe when used and fired as directed with a covering glaze, reassuring for functional work.
• Compact variety: The twelve 2-ounce jars let users try a broad 2020 color assortment without wasting studio space.

Who It's For

The sampler is ideal for hobbyists, students, and professional potters who want a manageable palette for detailed brushwork, watercolor effects, or sgraffito testing; the small jars are convenient for classes and workshops. It also suits makers who produce functional ware and need lead free underglazes that behave predictably through firing.

Those who need large-volume production supplies or who require highly specialized commercial colors should look elsewhere, as the 2-ounce jars are intended for sampling and small projects rather than long-term bulk use.
