Stage 1: Bag of Clay
- The First stage of making pottery is getting the bags of clay.
- Above we have red, speckled and white clay. These are the clays used by Stories N’ Stoneware most often.
- Next up is to make something out of it, known as the Greenware stage
Stage 2 : Greenware
- Pottery can be made several different ways, We most commonly use the pottery wheel
- Once the piece has been created or thrown it is left to dry until it becomes harder, this is called leather hard.
- Then the piece is trimmed and in the case of mugs a handle is pulled and added, like the video below
- And this is also the stage that underglazes are added if needed.
- Afterwards it is left to dry for a few days more to let all the water evaporate and is called bone dry
- This is when it is ready for the next stage, the bisque kiln fire
Stage 3: Bisqueware
- After getting bone dry the pieces are put in the first kiln fire, called the bisque fire
- The Bisque is fired to Cone 04 or around 1970 degrees Fahrenheit ( this can take several days to get to temp and to cool down)
- Once cool enough to remove for the kiln it is called bisqueware
- Bisqueware is now ready to be glazed.
Stage 4: Glazeware
- Once the pieces are glazed, they are put in the kiln for the final glaze fire.
- The kiln is fired to cone 5 or 6, depending on the clay and glazes around 2130- 2200 degrees Fahrenheit
- Then after the pieces are removed and tested, they are ready for use!
Additional Stages/ Firings?
Horse Hair Raku
Raku Reduction Fire
- There are alternative firings and addition firings of pieces as well
- Raku Horse hair pieces are bisque fired first and then heated in a kiln to cone 06-05 and then pulled while still hot to apply the horse hair (not food safe)
- Raku Reduction fire pieces are bisque fired and then heated in a kiln to cone 06-05 and then pulled while still hot and put in a metal can with sawdust and other combustibles until cool (not food safe)
- Luster fire is an additional kiln fire after the glaze fire. This includes silver, white gold, gold and mother of pearl luster. Luster is added to a glazeware piece and then fired to cone 020-018 and then are done when cool (luster are not dishwasher or microwave safe)
