A:While the mixing process is the same for fire clay mortar or refractory mortar, the portions of its materials will vary depending on the type of cement used. The mix for refractory or fire clay mortar is different from typical mortar to compensate for its exposure to high temperatures. Refractory mortar should also not be exposed on the inside part of an oven to minimize its shrinkage.
A:The main difference between porcelain and fine bone china is the inclusion of up to 50 percent bone ash in the porcelain mixture that makes up bone china. China is also typically fired at a lower temperature than porcelain, which is double-fired at very high temperatures.
