How should I apply Speedball Orange glaze for the best finish?

For uniform coverage and strong colour, apply multiple liberal coats rather than a single thin layer. Allow each coat to dry before adding the next; brushing, dipping, or pouring are all viable methods depending on your piece and desired texture.

• Apply 2–3 liberal coats for optimal opacity and saturation.
• Let each coat dry completely to avoid running or uneven surfaces.
• Use a soft, wide brush for large areas and a smaller brush for details and edges.
• Stir glaze thoroughly to recombine settled pigments before use.

What firing range and preparation does this glaze require?

Speedball orange glaze is made for earthenware bisqued to Cone 04 and should be fired to a finished temperature of Cone 05–06. Proper bisque preparation and kiln firing schedule are essential for colour stability and a durable surface.

• Bisque to Cone 04 before glazing for correct adhesion.
• Fire glazed ware to Cone 05–06 for maturation and glossy finish.
• Follow kiln ramp and soak recommendations suited to earthenware glazes.
• Avoid contaminating the glaze surface with glaze on foot rings; clean before firing.

Is this glaze safe for functional pottery and how durable is the finish?

The formulation is lead-free and labeled dinnerware-safe when applied and fired as instructed, making it suitable for plates, bowls, and cups. The final durability depends on firing accuracy and proper application; correctly fired pieces resist normal use.

• Lead-free composition reduces health concerns for food-contact items.
• Dinnerware safe when used and fired according to manufacturer guidance.
• Durability increases with even application and correct kiln firing.
• Test new glaze lots on sample pieces before committing to dinnerware production.

What effects or surface qualities can I expect from the orange colour?

The glaze produces a highly saturated, bright orange that fires consistently across pieces. Depending on application thickness and firing profile, the finish can range from glossy smooth to subtly variegated where brush strokes or pooling occur.

• Bright, highly saturated orange tone that maintains colour fidelity after firing.
• Gloss level can vary with coat thickness and kiln atmosphere.
• Thicker areas may pool slightly, creating depth or subtle shading.
• Compatible with underglazes and decorative techniques when properly tested.
