This is a step-by-step to wedge, roll out and cut specimen bars from a pugged material. These then need to be dried, dry measured, fired at various temperatures and then measured for weights and lengths again. The data gathered at various stages is fed into a recipe record in an account at Insight-live to create a profile (or physical characterization) of the material.
