Mayco SG-501 Sculpting Medium

Glaze Overview

Mix well. Apply with a brush, palette knife or squeegee directly on bisque or on top of an unfired glaze. Sculpting Medium has the viscosity of condensed milk and it can be brushed on or applied with a sponge.  The recommended application thickness is 1/16 to ⅛”. Sculpting Medium is quick drying. If desired, apply Stroke & Coat over Sculpting Medium to add color. Fire to shelf cone 05/06 (1031°C – 999°C); it will not perform at higher temperatures. The fired finish can be coarse and have rough edges; a layer of clear glaze (or a colored glaze) will smooth these sharp edges.

For use with a stencil, hold a stencil onto your piece and brush Sculpting Medium over the stencil. Allow the Medium to set up a bit (until the wet look is gone) and then remove the stencil.

Tips & Techniques:

• Sculpting Medium is sensitive to thicker applications. Creating a layer 1/8” may result in splits or cracks appearing in the fired surface. This may be an effect you intentionally wish to achieve; if not, keep the thickness below 1/8”.
• Quick drying means design integrity is maximized.
• Base glaze properties can impact your final surface. Applied over a moving glaze will cause the Sculpting Medium design to move and separate.
• After removing tools such as stencils or lace sharp, jagged edges may form. A moistened fan brush can be used to smooth these rough edges. You can also apply a glaze over the design to help smooth sharp effects.
• Sculpting Medium will shrink slightly over glaze. Needs to be fired at cone 05/06, otherwise the sculpting medium will gloss and soften the edges.
• Can be applied in a painterly fashion using brushstrokes or squeezed through a writer tip.
• Non-Toxic, Food Safe. Recommended for ornamental use only.

Glaze is a glassy melted coating that is fired onto ceramic pieces. Once fired, glazes may be glossy, satin, or matte. If you’re creating clay surfaces intended to hold food, a gloss glaze is an excellent option because it makes it easier to clean the dish. A matte glaze will be non-reflective and can be smooth or stony to the touch. Satin glazes will have a low, waxy sheen that is smooth in texture.

Underglazes are commercial products made up of finely ground clays and frits with oxides and stains. Underglazes usually require a clear or transparent glaze on top of them to seal the surface. You can paint, pour, spray, or dip the underglazes on your creations. Usually, underglazes require three coats. However, Clay-King offers one-coat products that are often fluxed to produce a low sheen.
