Bring consistent, high-impact colour to your pottery with this 16 oz jar of Speedball earthenware glaze. Developed for artists working with earthenware that’s been bisqued to Cone 04, this pink glaze matures between Cone 05 and 06 and is manufactured free of lead. It’s ideal for studio ceramics, classroom settings, and home potters who want bright, reliable hues. For predictable results, apply two to three full coats and follow kiln firing recommendations.

How will this glaze perform on my bisqued earthenware?

Speedball’s earthenware glazes are formulated for use on clay pieces that have been bisque-fired to Cone 04 and then glazed and fired to Cone 05–06. The colour is engineered to remain vibrant after firing, with a consistent finish across multiple firings when proper technique is used.

• Apply to bisqued ware at Cone 04 for best adhesion.
• Fires to maturity at Cone 05–06 — compatible with low-fire kilns.
• Produces saturated, true-to-tint pink after firing.
• Intended for earthenware clays rather than stoneware or porcelain at higher cones.

Is this glaze safe for functional tableware?

When applied and fired according to Speedball’s directions, the glaze is lead-free and marketed as dinnerware-safe. Proper application and correct kiln firing are essential to meet safety expectations for items that contact food.

• Formulated without lead in the colorant.
• Follow recommended coating thickness (2–3 liberal coats) for an even surface.
• Complete firing to Cone 05–06 to ensure durability and safety.
• Test finished pieces if you plan to sell or use them for commercial serving purposes.

What application and firing tips improve results?

For even coverage and reliable colour depth, apply two to three liberal coats and allow each layer to dry before adding the next. Avoid thin washes that can produce uneven tones or pinholing; consistent glaze thickness helps the pink colour develop fully during firing.

• Stir glaze thoroughly before use to reincorporate settled pigments.
• Brush, dip, or spray in generous coats, allowing drying between layers.
• Wipe foot rings clean to prevent sticking during glaze firing.
• Fire to Cone 05–06 according to kiln manufacturer schedules for best results.

How can I troubleshoot common glazing issues with this colour?

Uneven colour, crazing, or dull spots often come from inconsistent application, inadequate bisque level, or incorrect firing. Adjust application technique and double-check kiln temperature curves to resolve most problems.

• Uneven colour: increase to three coats or ensure each coat dries fully before next application.
• Crazing: verify clay body compatibility and firing schedule; test tiles to adjust fit.
• Pinholes or crawling: reduce dust on bisque surface and avoid overly thin coats.
• Dull patches: confirm full maturation at Cone 05–06 and consistent kiln heat-up/cool-down.
