Mayco | SW-425 Black Melt Gloop
Black Melt Gloop is a stoneware glaze designed for application in dots or creating a dripping effect down your ceramic piece.
The SW (Stoneware) series from Mayco consists of mid-range cone 6 glazes formulated for reliable performance on stoneware and porcelain bodies. These glazes develop rich variation, breaking, pooling, and visual depth depending on application thickness and clay type. Many Stoneware glazes are suitable for layering, overlapping, and combination effects, producing dynamic surfaces for both functional and decorative ware.
Mayco Colors is a leading manufacturer of ceramic materials and glazes known for reliable performance, innovative surfaces, and strong support for artists, educators, and studios. Their products are widely used for both functional and decorative ceramic work across firing ranges.
Product Code: SW-425
- Effects are achieved by applying glaze with a syringe or squeeze bottle on greenware or soft-fired, cone 04 stoneware bisque (1940°F/1060°C).
- For a more dynamic effect and a dripping appearance, apply larger dots on a vertical surface.
- The glaze can flow over textured areas.
- For better adhesion, dampen the bisque with a sponge before applying.
- Heavy application or over-handling may cause the glaze to pop off. Handle with care.
- Can be layered and marbled with other Melt Gloop colors.
- When using Melt Gloop over a Stoneware Engobe or Underglaze, it is recommended to bisque fire to cone 04 before applying Melt Gloop.
- Glaze remains dimensional over Underglazes and Stoneware Engobes; flattens under or over a glaze.
- It is recommended to fire your piece as soon as possible to prevent issues with glaze adhesion.
- When applied as a horizontal line, the fired glaze effect may separate or break, turning into vertical drips.
- When building layers, it is recommended to apply glaze on the shoulder or rim of the piece to help with adhesion.
