Description

一种煅烧陶土及其制备方法
技术领域
本发明涉及一种煅烧陶土及其制备方法。
背景技术
钦州坭兴陶，作为一种传统民间工艺，至今已有1300多年的历史。传统钦州坭兴陶的制备工艺主要包括以下几个步骤：1) 制备坯料：坯料由陶土材料制成，选用横穿钦州 市区的钦江以东的泥土（俗称东泥：为软质粘土，颜色为黄白色，含微量石英砂，在坭兴陶的生产工艺中起调整可塑性及结合性的作用）和钦江以西地域的泥土（俗称西泥：是一种含铁量较高的紫泥石，颜色为紫红色，表面层有少量铁质浸染，为硬质粘土，可塑性及结合性较差），以东泥 40～60％、西泥60～40％的重量百分比混合；2) 坯体成型 ；3)坯体修整 ；4)坯体干燥；5) 装饰坯体 ：坭兴陶在制作过程中既不添加任何颜料、不上釉，也不在坯体上用 任何着色材料描绘色彩和图案，仅依靠偶尔出现的窑变使坭兴陶呈现无法预测和控制的色 彩，及使用雕刻工艺来装饰坯体。6) 烧制 ：将装饰好的坯体装窑烧制；为了达到较高的烧成 率及提高窑变率，坯体烧制的最高温度控制在1100～ 1200℃，烧制时间为10小时，经烧制后出窑即为坭兴陶器。使用不同坯料制备的陶器坯体，所能承受的烧制温度是有差异的。坭 兴陶坯体是以东泥和西泥两种陶土材料制成，不耐高温，烧制温度超过1200℃，坯体表面会 出现裂纹或破损，严重的甚至出现坯体变形和坍塌，故在装饰坭兴陶坯体时，不能使用必须 经高温烧制才能显色的着色材料描绘纹饰、图案，只依靠烧制时偶尔出现的窑变，使坭兴陶出现不同色彩。
发明内容
