Glossy Clear Liner Cone 6 (Mastering Glazes)
Recipe
Notes
Optimized for its role as an interior "shield." Key Properties • Visual Appearance: Crystal clear. • The Science: This is a high-calcium, boron-balanced glass that is resistant to corrosion. • Surface: It creates a "glass-like" interior that is highly resistant to staining from coffee, tea, or metal spoon marks. • Thermal Fit: It has a low-to-medium thermal expansion giving "fit" on most bodies. Likes (Pros) • Unmatched Stability: It does not run, it does not crawl, and it rarely pinholes. It is the "safe bet" for the inside of any functional vessel. • Easy Cleaning: Because the surface is so dense and glossy, it is the most "dishwasher-friendly" glaze in the Hesselberth/Roy collection. • Shows Detail: If you use a white clay body or porcelain, this glaze makes the piece look like fine china. It also works well over slips or underglaze paintings without blurring the lines. • No "Clouding": Many clear glazes turn milky or cloudy if applied too thick. The Page 97 Liner is formulated to stay clear even if the application is slightly heavy. Dislikes (Cons) • Strict Application: Because it is a "stiff" melt, a bubble or a "crater" might not flow enough to fill it in during the firing. • Highlighting Imperfections: Because it is clear, it hides nothing.
