Product Overview

PLEASE NOTE SPRING 2021 BRACKER’S IS NOW SELLING CLAY BY THE BOX, NOT BY THE POUND, PLEASE SELECT NUMBER OF 50# BOXES YOU WANT

A general purpose low-fire white clay for electric kiln firing. Fires very white. Shows glazes well.
 
During the summer of 2020, we completed a comprehensive test of our clay bodies.  For each clay body, we tested 6 flat bars, which were rolled out on a slabroller.  We ALSO tested vertical shrinkage of a thrown cylinder (6 sections, each with their own test)

  • beginning weights in grams were recorded
  • the lines and weights were measured & recorded when bone dry
  • The samples were fired to Cone 04
  • lines and weights were measured & recorded again
  • The flat tiles were then soaked in hot water for 1 1/2 hours, then weighed again
  • Math magic was then done to calculate the average shrinkage wet-dry and average shrinkage overall for both flat and thrown tests, and the average water absorption was calculated based on the flat bars.
  • We also figured the "LOI" (Loss on Ignition) by computing the fired weight against the bone dry weight.  This tells us what percent of organics burn off in the firing.
