Cracked glaze ceramic, preparation method of cracked glaze ceramic and environment-friendly ceramic handicraft
The invention discloses a crackle glaze ceramic, a preparation method thereof and an environment-friendly ceramic handicraft, and belongs to the technical field of ceramic glazes, the crackle glaze ceramic comprises a blank and a glaze in percentage by mass, the blank comprises 25-40% of quartz and 60-75% of anorthite; the glaze is prepared from 55 to 70 percent of quartz, 10 to 15 percent of potassium feldspar, 10 to 15 percent of albite and 10 to 15 percent of a phosphonic acid product; when the cracked glaze ceramic is fired, the high-temperature viscosity of the glaze is remarkably increased, the flowability of the glaze is small, glaze cracking caused by overfiring of the glaze in advance in the firing process is prevented, the thermal expansion coefficient of a glaze layer is remarkably increased after firing, and the glaze layer is easier to crack and crack after being cooled.
本发明公开了一种裂纹釉陶瓷、裂纹釉陶瓷制备方法及环保型陶瓷工艺品，属于陶瓷釉技术领域，按照质量百分比计，包括坯料和釉料，所述坯料包括25～40％的石英、60～75％的钙长石；所述釉料包括55～70％的石英、10～15％的钾长石、10～15％的钠长石、10～15％的膦酸化产物；本发明的一种裂纹釉陶瓷烧成时，釉料的高温粘度显著增加，釉料的流动性小，防止烧成过程中因为釉料的过烧所提前引起的釉裂，烧成后，釉层的热膨胀系数显著增加，经冷却釉层更容易开裂，形成裂纹。
