Glaze material for firing Longquan celadon thick glaze and firing process
The invention discloses a glaze material for firing Longquan celadon thick glaze and a firing process. The dry material part of the glaze material comprises the following components in parts by weight: 40-50 parts of Zijin clay, 15-20 parts of quartz, 12-15 parts of talc, and 6-8 parts of silica fume. The process comprises the steps of S1, preparing a green body; S2, preparing glaze slip; S3, sintering the blank and glazing; and S4, firing. The talc is added into the glaze material, so that the plastic property of the glaze material can be reduced, the occurrence probability of glaze shrinkage is avoided, the silica fume has extremely high surface activity, the activity of the glaze material can be enhanced, the glaze material is attached to the surface of a biscuit more compactly, pinhole-shaped dead pixels generated when gas enters glaze slip in the firing process can be improved, and the roughness of the glaze surface is reduced. According to the Longquan celadon thick glaze fired by adopting the glaze material and the firing process disclosed by the invention, under the condition that the glaze material with the same thickness is applied, the glaze material on a biscuit does not flow, so that the occurrence of glaze flowing and glaze shrinking is reduced to a great extent, the yield of the Longquan celadon thick glaze is enhanced, and the jade texture is strong.
本发明公开了一种烧制龙泉青瓷厚釉的釉料及烧制工艺，所述釉料的干料部分按重量份包括组分：紫金土40～50份；石英15～20份；滑石12～15份；微硅粉6～8份；工艺包括如下步骤：S1、制作坯体；S2、制釉浆；S3、烧坯施釉；S4、烧制。本发明通过在釉料中添加滑石，可降低釉料塑性性状，避免发生缩釉的发生几率，微硅粉具有极强的表面活性，可增强釉料的活性，使得釉料在素坯表面附着更加紧实，可改善烧制中气体进入釉浆发生针孔状坏点，降低了釉面粗糙度，采用本发明的釉料及烧制工艺烧制的龙泉青瓷厚釉在同样厚度的釉料施加情况下，素坯上的釉料不会发生流动，很大程度上减少了流釉、缩釉的发生，增强了龙泉青瓷厚釉的成品率，玉质感强烈。
