During the greenware stage water has evaporated from the clay body and the clay is very stiff. It cannot be bent without cracking but can still be carved or added upon.
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.
Greenware is usually fired at cone 06 for bisque firing. The glaze firing depends on the maturation temperature of the clay and the glaze.
greenware
Unfired pottery. Usually dry unfired things but it could be leather hard and not yet dry as well.
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.

Yes, greenware is compostable because it is made from plant-based materials that can break down naturally in a composting environment.
Yes, greenware, which refers to unfired pottery or ceramics, is recyclable. It can be broken down and reused to create new pottery or ceramics.

greenware
The removal of the seam left by the mould in greenware, by fettling knife and/or sponge.
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).
You obtain "greenware" tiles, which have not been fired. Then, you transfer the printing (probably a specialty item) and fire the tile.

The act of"firing" in ceramics involves applying a coat of mineral glaze to the dry clay surface , which when placed in a" kiln" (high heat oven for baking ceramics) a glossy or matte colored finish on the ceramic surface is achieved. Raw clay ceramics are called greenware. Once fired ceramic pieces are called bisque ware. Glazing or raku is the final application of the colors and finish. This process is how floor tiles are made. These finishes are permanent and become a part of the chemical structure of the item. The act of "firing" in the business world means dismissing an employee for violation of company policies and guidelines, absenteeism or poor performance.
