The One-Stroke 600 Series Underglazes are all lead-free, dinnerware safe, and A/P non-toxic when covered with a clear glaze. One-Strokes can be used at almost any temperature range and can be applied to bisque or raw clay. Due to their high concentration One-Strokes only need 1 application for full opaque coverage. The samples shown are at Cone 05, but the One-Strokes can be fired from low-temperature (cone 06/04) to high temperature (cone 9/10). Some colour variation will occur at higher temperatures and also different clear coats glaze thickness can affect the hue of each One-Stroke underglaze.

• Opaque coverage with one stroke. 
• Intermixable to create your own colours.
• Wide firing range of Cone 06/04 to Cone 9/10.
• Can be applied to Greenware and Bisque.
