greenware
Do I have to fire an underglaze before applying a glaze?
Yes, it is generally recommended to fire an underglaze before applying a clear glaze. This initial firing helps to fix the underglaze color and prevents it from mixing with the glaze during the second firing. However, some underglazes can be applied directly to greenware and then glazed without an intermediate firing, but it's essential to check the manufacturer's instructions for specific products.
What is a fired clay piece called?
A general term for unfired clay products is "greenware." The exact designation of unfired clay, however, depends on the stage of dryness. In order by increasing dryness, clay can become soft leatherhard, firm leatherhard, velvet and bone dry.

What temperature do you fire greenware for a cone04?
Greenware is typically fired at a lower temperature known as a bisque firing before glazing. For cone 04 clay, it is fired to around cone 04 temperature, which is approximately 1945°F (1063°C).
What Temperature is greenware fired at to become bisqueware if it fired to a cone 04?
Greenware is typically fired to cone 04, which corresponds to a temperature of around 1,940°F (1,060°C). This initial firing transforms the raw clay into bisqueware by removing moisture and organic materials, making it more durable and ready for glazing. The bisque firing also helps to vitrify the clay slightly, enhancing its strength and porosity for subsequent glazing.
Is greenware compostable?
Yes, greenware is compostable because it is made from plant-based materials that can break down naturally in a composting environment.

What happens when you put underglaze that's for bisqueware on greenware?
The worst thing I have personally seen happen is that the color is very muted and sometimes bubbly. I would bisque fire it and see what it looks like. I haven't heard of any explosions or serious cracking issues associated with this. If the color is bad after bisque firing, I would try to do a glaze firing. Hopefully the glaze will fully cover the underglaze.
