 Not sure exactly what information this procedure provides but pretty sure it isn't absorption!

Weigh on gram scale and subsequently Boil a bisqued slab bar in water for four hours.  Then high fire to intended cone. (not to a set temp) use a cone as true "Heatwork" Baseline. Weigh again and do the math for percentage of absorption.
