Can pure kaolin or montmorillonite burn pottery? If not, what do you need to add?
Pure can pottery, such as white is pure kaoline. In addition, according to the needs of different types of ceramic added into material, such as sand pottery in the need to add fine sand, in order to increase the thermal shock resistance performance of pottery. Then such as pottery pottery pottery, these different colors are made by feeding and then control the roasting conditions.
Kaolin is hard or soft, chemical properties are similar, but the physical properties of different, soft adhesion, plasticity, suitable for ceramics.
More than two of the hard nature of the poor, so the use of ceramics in relatively small, mainly chemical raw materials. However, because of the scarcity of soft soil and higher prices, many manufacturers have been studying the hard kaolin and other viscous ores to achieve the above results. That is, it can reduce the cost and produce better ceramics.
