釉的特性常常被认为是决定釉面陶瓷抗热震开裂的唯一重要因素。在这项研究中，它被发现，热冲击银纹是造成的，在某些情况下，银纹状裂纹的机构发展。选择合适的物体作为控制银纹的一种手段的重要性，在人们发现具有高抗热震性的物体在上釉和经受突然的温度变化时，不像那些抗热震性低的物体那样容易产生银纹时，就立刻变得明显起来。一般说来，釉在相当高的压力下的釉面制品比釉在低的压力或张力下的釉面制品更能抵抗热冲击开裂。对热冲击开裂敏感的釉面器皿可以抵抗湿气开裂，反之亦然。
The characteristics of glazes are too frequently regarded as the only important factor governing the resistance of glazed ware to thermal shock crazing. In this investigation it was found that thermal shock crazing was caused, in some cases, by craze-like cracks which developed in the bodies. The importance of selecting suitable bodies, as a means of controlling crazing, became evident at once when it was found that bodies with a high resistance to thermal shock were not so liable to craze when glazed and subjected to sudden temperature changes as those with a low resistance to thermal shock. In general, glazed ware on which the glazes are under fairly high compression are more resistant to thermal shock crazing than those on which the glaze is under either low compression or tension. Glazed ware which is susceptible to thermal shock crazing may be resistant to moisture crazing and vice versa.
