"In as much as the grinding of insulating brick to size after the firing operation is one of the most important and at the same time one of the most expensive operations involved in their manufacture, it was felt that the development of a method for manufacture of insulating brick which would do away with the necessity of grinding after firing would be a very worth while project. With this object in mind it was decided that the logical method would be to incorporate the pore structure in the mix while green and at the same time to add some agent which would prevent loss of the pore structure before the body was strong enough to support it's sic own weight. We decided to produce the pore structure in the brick by means of a soap froth and to add liquid paraffine sic to the slip before it was poured into the mold. The paraffine sic would solidify quickly and permit the removal of the green brick from the mold with no danger of its slumping or losing its shape before being fired"--Purpose, page 5.
