PRODUCT DESCRIPTION

Our in-house brand of stoneware has been created for making functional and non-functional pieces and can be paired with a wide-range of Clay Station as well as other glazes. It fires to black color when it is fired in the oxidation atmosphere. This clay is ideal for hand building, wheel throwing and sculpting. 

  • Turns into maroon color after the Bisque firing (998 Deg C)
  • Turns into black color when it's fired to Cone 6 (1223 Deg C) 

 Clay Properties:

Bisque Temperature  Cone 06, 998 Deg C
Bisque Porosity 12-14 %
Glaze Temperature  Cone 6 with 30 minutes hold, 1223 Deg C
Total Shrinkage  12-14 %
Final Porosity 0-1 %


  • This clay tested in the Oxidation atmosphere. Might not be the good option in the reduction atmosphere, Tend to bloat  
  • Maximum working temperature is Cone 7, 1239 Deg C 

These properties can change if fired at different temperature. Few clay properties differ between handmade and wheel-thrown pieces, so here's more data for clarity. 

1. Hand building fired @ Cone 6 (1223 Deg C), 30 minutes hold:

Dry Shrinkage  6-7 %
Fired Shrinkage  5-6 %
Final Shrinkage  12-13%
Absorption  0-1 %


2. Wheel throwing fired @ Cone 6 (1223 Deg C), 30 minutes hold: :

Dry Shrinkage  7-8 %
Fired Shrinkage  6-7 %
Final Shrinkage  13-14%
Absorption  0-1 %

 

Additional Information:

  • Dry shrinkage is determined by measuring the reduction in shrinkage after the manufacturing stage to the bone-dried stage.

  • Firing shrinkage is determined by measuring the reduction in shrinkage after the bone-dried stage to the final fired stage (Cone 6 or Cone 7)

  • Absorption is also called as porosity of a clay body 

  • The color of a clay depends on the firing temperature. At cone 6, 30 mins hold will give the darker color. ( Higher the firing temperature gives darker color
  • Drop - Hold firing schedule (at 1180 Deg C) might eliminate the pinholing defects in the glazed articles  

Notes:

  • Testing the glaze with the clay body is recommended due to the elevated Iron content, ensuring the compatibility
  • The drying and overall shrinkage of wheel-thrown articles can differ based on the water content used while making
  • To obtain batch-specific shrinkage and porosity details for bulk orders, please reach out to us at 9108852707

Shipping and delivery:

For order quantity more than 100 kgs, if you prefer to opt for customized shipping rates, use warehouse pick up option during check out. Our representative will call to coordinate.
