Gelwhite H

Description: Highly refined bentonite plasticizer

Notes

A very white burning highly processed montmorillonite material (similar to Mineral Colloid BP from the same company, Southern Clay Products). Although this material is targeted at the cosmetics industry, it can be useful in ceramics as a white burning plasticizer. These materials are almost equal to Veegum for use in producing very white burning plastic porcelains.

Was made by Southern Clay products but discontinued by new owners.

Each has been mixed with water and all produce a jelly-like translucent sticky material that takes a very very long time to dry. They are expensive and, among other uses, act as white-burning plasticizers in fine porcelain bodies.

The Veegum is dense and white, but not melting. The Mineral Colloid fires like a typical raw bentonite (dark brown, high soluble salts and beginning to melt). The Gelwhite is completely melted and foamed.
