Step 8: Measuring the clay test bars after drying

These test specimens dried overnight (this in itself is pertinent - quick drying indicates low levels of superfine particles e.g. bentonite). Here, I am measuring the length of the SHAB test bars, weighing the LDW test sample and recording the crack pattern and soluble salts on the DFAC test disk. All of this data plugs into the recipe I have allocated for this project in my account at Insight-live.com, you can it here on the inset screenshot. Next I’ll set these on our staging shelf for firing in the test kiln (we accumulate test bars for 16 temperatures).
