Mayco Stoneware Magma Glaze pint - Light volcanic texture, mid-fire cratered finish

Mayco Stoneware Magma Glaze in Light (pint) is a mid-fire, texture-enhancing glaze that creates a rough, cratered surface when applied to bisqueware or layered over other stoneware glazes.

Bring tactile depth and volcanic-inspired finishes to your pottery with Mayco's Stoneware Magma Glaze — Light. Formulated for mid-fire temperatures, this pint-sized glaze produces pronounced texture and crater-like formations that give functional ware and sculptural pieces a rugged, artisanal look. It is versatile enough to use straight from the bottle on bisqueware or to combine with other glazes for varied visual and tactile effects.

How does this glaze create its cratered surface?

The textured, volcanic finish comes from the glaze formulation that bubbles and pulls back during firing, producing small pits and raised edges. Application thickness, firing schedule, and interactions with underglazes or other topcoats all change how pronounced the texture becomes.

• Thicker coats deepen craters and increase surface relief.
• Thinner coats give subtler texture and more colour clarity.
• Layering over glossy glazes can create contrast between smooth and rough areas.

What firing range and preparation does it require?

Mayco Stoneware Magma Glaze is formulated for mid-fire stoneware firings; follow your kiln’s recommended temperature range for mid-fire glazes. Apply to clean, dry bisque-fired ware and test-fire a sample piece first to dial in application thickness and desired texture.

• Apply to bisqueware that has been sanded and wiped free of dust.
• Fire to the mid-fire cone range appropriate for your kiln and clay body.
• Always test on representative pieces—thin, thick, and layered—to predict results.

How can I combine this glaze with others for custom effects?

Mayco Magma Glaze works well as a single finish or combined with other stoneware glazes to add surface interest and colour variation. Try underglazes, slips, or glossy topcoats to produce contrasts between cratered texture and smooth sheen.

• Apply an underglaze or coloured slip first, then brush or pour Magma Glaze on top for textured highlights.
• Combine with a glossy transparent glaze in areas to create smooth islands amid rough textures.
• Use spattering or brushing techniques to control where craters form.

How much coverage does a pint provide and how should I store it?

A 16 oz (pint) container provides enough material for multiple small pieces or several accent applications on larger work, depending on application thickness. Keep the lid sealed and store in a cool, stable environment to preserve consistency between sessions.

• Estimate coverage by application method: brushing uses less than pouring or dipping.
• Re-stir before use to reincorporate settled solids; strain if needed for smooth application.
• Label jars with batch/date if you mix or thin the glaze for reproducibility.

Who is this for: Potters and ceramic artists who want bold, tactile surfaces—this glaze suits hobbyists, studio artists, and small-batch makers aiming to add volcanic texture and visual contrast to tableware, sculptural pieces, and decorative objects. If you value surface interest, layering experimentation, and mid-fire compatibility, Mayco Stoneware Magma Glaze — Light gives you a controllable way to introduce dramatic texture without complex firing schedules.
