Crinkle dichroic is a smooth glass that changes texture when fired in a glass fusing kiln. Unlike normal dichroic, which apart from the textured styles, will be smooth after firing.
This textured dichroic made by CBS can be used on its own or used with smooth dichroic pieces in glass jewelry designs.
Kiln fired hot at about 1475 F or higher the coating will push upwards and crystallize. According to the maker this results in thousands of crystalline-like mirrors attracting light and sending it out in all directions.
Subject to the style chosen and the glass fusing temperature various degrees of texture change will occur. As seen from the photo below the surface is only moderately changed. This change is much greater with other colors and styles.
