LOW-FIRE CLAY (earthenware/terra cotta) is a porous, iron-rich clay fired at low temperatures Cone 06-04, ~1830°F–1940°F, ideal for bright glazes, beginners, and decorative, non-functional pieces. It is made of natural earth minerals and is soft and highly absorbent after firing.
- Composition: Primarily earthy clays like terracotta or refined red clays that remain soft and porous even after firing.
-
Primary Uses:
- Decorative Wares: Best for sculptural, artistic pieces, and decorative items that don't require water tightness.
- Bright Color Work: Allows for vibrant glaze colors that cannot survive higher temperatures.
- Schools/Beginners: Accessible and safe to fire; easy for hand-building and throwing.
- Planters/Pots: The high porosity allows clay to "breathe," making it great for plant health.
- Best Features: It is cost-effective, allows for fast firing, and produces very bright, vibrant glazes.
NO-FIRE CLAY (air-dry/polymer) is made of non-clay ingredients, curing without a kiln
- Composition: These are often polymer-based or natural clay mixed with binders and oils that harden through air exposure.
- Uses: Used for crafts, sculpture, and jewelry where a kiln is unavailable.
