Mayco SW-4 is a clear, glossy, zinc-free glaze that is particularly well-suited for use with chromium-based pigments, such as underglazes. When fired around 1240°C (2264°F), it produces a smooth, clean, glossy surface that allows colors and decorations to stand out clearly.
The glaze is stable within the temperature range of 1200–1300 °C. The final result may vary depending on clay type, application, layer thickness, and firing, among other factors. For best results, it is recommended to test the glaze on test pieces before use on finished works. Follow the manufacturer's instructions for firing and temperature.
Follow the manufacturer's instructions and use normal precautions when handling glazes.
