Glossy Base 2 Cone 6 (Mastering Glazes)
Recipe
Notes
The Glossy Clear Liner from Mastering Cone 6 Glazes is arguably the most important recipe in the book. It is the most stable and food-safe for durable interior surfaces. Key Properties • Transparent and colorless, a balanced Borosilicate glass. • Surface: A hard, glass-like finish that is easy to clean and resistant to the "etching" effects of dishwashers and acidic foods. • Thermal Fit: It is formulated with a "middle-of-the-road" thermal expansion, meaning it fits a wide variety of commercial Cone 6 stoneware and porcelain bodies without crazing or shivering. Likes (Pros) • Food Safety: It has been tested rigorously. • Clarity: The best choice for protecting underglaze designs or highlighting a white porcelain. • Easy to Use: It has excellent suspension properties (it doesn't turn into a "brick" at the bottom of the bucket) and a wide firing range. It looks as good at a soft Cone 6 as it does at a hot Cone 7. • High Gloss: The surface is brilliantly reflective, which helps brighten the interior of mugs and bowls, making the food or drink inside look more appealing. Dislikes (Cons) • Application Bubbles: Because it is a "stiff" clear (meaning it doesn't move much), it can trap tiny micro-bubbles that look like "dust" inside the glass. • "Boring" on its own: It is purely functional. • Shows Every Flaw: Any smudge, fingerprint, dust or iron spot on the raw clay will be magnified once fired.
