4.1.3 natural relief glaze composition and content of ore

1 Introduction

Ceramic production in practice, because of improper operation of certain processes, the general will lead to products of partial burning glaze or glaze a large area reduction, which seriously affect the product quality and economic benefits. However, is this "bad situation" has given us an unexpected harvest: the use of "defective" human shape "natural relief" sense of beauty, developed a ceramic glaze on the formation of the natural method of relief with their use ceramic glaze (the text referred to as "natural glaze relief"), and in September 2005 by the State Intellectual Property Office granted patents for their invention. 2, the technical background

Ceramic surface to form a convex-concave relief and has a distinct three-dimensional sense of beauty, traditional methods are the use of sculpture, by means of landfill or transfer in ceramic green artificial form. However, the effects of this far from ideal - - Depression glaze thicker parts of the plot, no embossing, fuzzy edges and corners, the lack of three-dimensional sense of the complex process Moreover, the high costs. Ways to natural relief and more simple, arising from the effect of relief is clear, and its smooth lines, texture clear, smooth and delicate glazed, full of highly ornamental and applicability. Therefore, through the glazed decorative natural method of relief should have broad market prospects. 3, Technology Analysis

Through the ceramic green or green on the Shih Su-burning natural relief certain thickness of enamel, in the drying process because of cracks resulting from shrinkage cracks, the glaze to make glaze burning glass, and control the temperature so that the glaze with the appropriate liquidity, glaze their own surface tension crack and break in the action of their aggregation into droplets, thereby creating a natural effect of raised reliefs. 4, formula and practices

4.1 (embossed glaze with the system

4.1.1 the required percentage of the ore and its content (see table)

4.1.2 Distribution system measures and steps

Formula required by the volume of the original ore, by crushing a few 260 mesh, stirring evenly into after the ball milling container, plus the weight of 1:1, such as clean water, placing a sealed ball-milling for 50 hours, from glaze slurry that is "relief glaze."

4.1.3 glaze carved mineral composition and content (see table right) 5, process

5.1 embossed glaze decoration a natural way

5.1.1 General Decoration

First of all, the green ceramic blanks or Su-burning clean, proper pay;

Secondly, do not form a relief glazed containers of parts such as ceramic wall subjected to the usual transparent glaze or glaze;

Third, the use of the traditional transfer printing process, if necessary, the regional formation of colorful designs, patterns and figures of animals and birds.

Finally, in the formation of the necessary parts or regions such as the appearance of porcelain-walled containers, flat porcelain spraying the outer edge, Brush or Immersion methods Chiu admitted glazing, glaze layer thickness after drying the best guarantee of 0.6-0.8mm, uniformly smooth, in order to in the drying process due to cracks generated substantial crack, crack the glaze layer has been split into numerous small pieces, and form the embryonic form of relief.
5.1.2 Art Deco

Relief in natural glaze add the usual color of ceramic-based materials can form a variety of colors of the ceramic glaze, or add the following composition and ratio of the composition of color-based materials can also achieve this effect.

Zirconium Silicate from 52-72%, cobalt chloride 9 - -29%, chromium oxide green 2-10% (weight percent) constitute a black-color-based materials in order to add the ratio of 5.3:100 natural relief glaze, burning After the products of "relief" is black.

From 6-26% iron oxide red, chromium chloride, Green 4-24%, 39-59% zinc oxide, alumina 10-30% (weight percent) constitute a brown color-based materials in order to add the ratio of 1.96:100 add the proportion of natural relief glaze, fired after the products of "relief" is brown.

By iron oxide red, zircon, cadmium oxide, potassium chromate, tin oxide, magnesium oxide and the dispersing agent consisting of a red color-based materials to add 2-6:100 the proportion of natural relief glaze, fired after the products " relief "is red.

From vanadium oxide, zirconia, cobalt oxide, zinc oxide consisting of a blue-color-based materials to 2-6:100 (weight ratio), the ratio of natural relief add glaze, fired after the products of "relief" for the blue.

In addition, the ceramic green or green on the Su-burning ceramic coating commonly used paint colors, and then will be able to impose relief glaze has formed the background color of the glazed reliefs. Can also be color-based materials after spraying the glaze on the glazing layer, the glaze after firing have the same color to form massive bump relief.
5.1.3 Sintering Products

Glazing process is complete, the use of oxidation firing. Paste products such as paper flower should have in the 850-900 ° C temperature Pai membrane, and then gradually heating to 1210 ° C (optimum temperature should be 1190-1220 ° C), holding time 5-10 minutes, then cooling off. This glazed ceramics from the naturally formed will bump clearly feeling the shape of delicate relief.

Of course, it is worth noting is the best glaze firing temperature ceramic glaze composition must change a little change, a word should be higher than the ceramic glaze glass transition temperature, but when the temperature is too high such as the viscosity of ceramic glaze is too small, the mobility of too large and the effect of the impact of relief. 6, conclusions phrase

Glazed ceramic formed into a natural relief methods traditional and modern decoration of glazed ceramics in one process to the physical and chemical reactions result of organically scientifically carving updated manually. It is not only substantial savings in production costs, improve production efficiency, more are able to obtain artificial and should not by the special effects, but also widely used in daily-use ceramics, crafts ceramics and building sanitary ceramics production areas, especially in the application of ceramic technology , able to adapt to domestic and foreign, especially European and American market demands. In Canton by a lot of customers, in order to create the benefits.
