Notes
In Mastering Cone 6 Glazes, the Glossy Clear Liner is meant to stay clear. This base is adapted to being a foundation for color experiments using oxides and stains.
Key Properties
• Visual Appearance: In its base form, it is a clean, transparent-to-translucent gloss. It is slightly more "active" than the Liner glaze, having a bit more depth and fluid character.
• The Science: It is a Calcium-Alumina-Silicate glaze. It accepts colorants more vibrantly, especially Chrome, Cobalt, Copper, and Iron.
• Surface: High-gloss and reflective. It creates a "wet look" that can make colors pop and appear more saturated.
• Versatility: It is stable enough for functional ware but responsive enough to be used for decorative layering.
Likes (Pros)
• A "Canvas": This is the best recipe in the book for creating your own "house colors."
• Excellent Melt: It has a very reliable melt at Cone 6. It flows just enough to smooth out any brush strokes or uneven dipping marks.
• Strong Color Development: It doesn't "muddy" colors. Blues come out crisp, and greens come out bright.
• Durability: It meets the authors' standards for stability and acid resistance, making it suitable for the outside (and often inside) of dinnerware.
Dislikes (Cons)
• Crazing Risk: Like many glossy glazes, it has a moderate thermal expansion. It may craze on low-expansion clays (like some high-iron red stonewares).
• Thickness Sensitivity: While it isn't as runny as Waterfall Brown, it is more mobile than the High Calcium Mattes.
• Bubbling on Dark Clays: On certain dark, gas-heavy clay bodies, this can occasionally trap "off-gassing" bubbles, resulting in tiny pinholes if the kiln isn't soaked at the peak temperature.

Recipes from Mastering Glazes Book
Descriptions of these glazes often contain marketing terms over-the-top adjectives like “scientifically formulated”, “perfect”, “exceptional”, “beautifully”, “engineered”, “specifically designed”, “sophisticated”, “flying colors”, etc. Of course there are no perfect recipes to be discovered, they all inhabit spaces balancing a dozen different properties, tuning one most often affects one or more of the others. And, recipe is only one thing affecting the finished product, process factors can have even more influence on finished appearance and properties. |

Transparent Glaze Recipe
Transparent recipes can be difficult to develop because entrained bubbles, crystals and crazing are not hidden by color and opacity. In addition, they must be well melted to give good results. Generally transparent recipes are sought after as liner glazes or bases to which to add opacifiers and colors. Typically work is required to match a transparent glaze to a specific clay body. |
