The kaolin in this area is well-known for its high purity and maturity due to the geological processes that led to its origin. The samples were taken from the production route after bleaching, demagnetizing, and milling, and they are representative of the typical feeds used for calcination. The samples were calcined in the laboratory using a ...
Using about half calcined. (or more)and half raw in a slip glaze recipe will help eliminate that issue. Many slip glazes with Alberta or Albany are almost all clay. I try not to have more than 10% raw clay in may glazes with the balance calcined clay. For me 10% will keep most ingredients in suspension and not hard pan.

(GEP), artificial neural networks (ANN), artificial neurofuzzy inference system (ANFIS), support vector machines (SVM) etc. are the most well-known examples to soft computing techniques. Among …
Calcined Kaolin is in effect about 10% more concentrated than non calcined. So on that basis if the recipe calls for 100 grams of calcined that would equate to approximately 110% of non calcined. Calcining removes the chemically combined water but also remove some trace amounts of some minerals usually found in EPK.
Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or …
So basically you're pre-shrinking the clay. In the case of kaolin, you're getting rid of about 15% shrinkage, which is significant if you've got a glaze or such that's high in kaolin. For instance, if you've read the threads about kiln wash, we always mention calcining half the kaolin for recipes that have 20-30% in them.
Calcination. Calcining is simply firing a ceramic material to create a powder of new physical properties. Often it is done to kill the plasticity or burn away the hydrates, carbonates, sulfates of a clay or refractory material.
