How to distinguish between the ceramic color glaze, glaze and glaze color?

& amp; nbsp; overglaze colors: the so-called glaze color, is the first firing glaze ceramics, in white glaze paint or decals, re-entry into the kiln by Celsius 600 to 900 degrees temperature baking and. Touch with the hand will have a sense of projection, a slightly convex pattern, the operation is more convenient than the color of the glaze. But the brightness of the picture is poor, and it is easy to wear and change after long use. The process is simple, the time is short, the yield is high, and the labor productivity is high. Br; /> <

Glaze: with overglaze production process is the same, the firing temperature is different, namely in the firing of white were painted (Decal), enamel firing temperature for heavy 1060& mdash; 1250 DEG C, color burn time for 90& mdash; 100 minutes. Glaze that under the conditions of high temperature fast firing, glazed products softening and melting, make the new pigment particle penetration glaze inside, when cooling after glazed closed, design and color is then immersed in the glaze makes the appearance becomes moist and indistinct, fine crystal, quite the effect of under glaze color. At the same time, it also solved the harm of lead toxicity. Br; /> <

Underglaze color: under glaze color is a major means of decoration for ceramics, is a pigment used in forming dry biscuit (semi-finished products) to draw a variety of patterns, and then cover with transparent glaze white or other light colored surface glaze, kiln (1200& mdash; 1400 DEG C) high temperature burning at a time. After firing pattern is a layer of transparent glaze film covering on the bottom, the surface light soft, smooth and does not protrude, is glittering and translucent and bright. It is characterized by a well preserved color, durable. Low finished product rate and high cost.
