Advantages:
1. Full-polished glaze is a special formula glaze that can be polished on the glaze surface. It is a glaze applied to antique tiles. Currently, it is generally transparent. Glaze or transparent convex flower glaze, the fully polished glazed tile that is applied to the fully polished glaze combines the advantages of polished tiles and antique tiles. The glazed surface is as smooth and clean as polished tiles, and its glazed colors are as rich as antique tiles. , The color is heavy or gorgeous.
2. The characteristic of the glaze is that it is transparent and does not cover the top glaze and various flower glazes. When the glaze is polished, only a thin layer of the transparent glaze is thrown away, while the transparent convex flower glaze is completely polished. The glaze is an outstanding work of the beautiful ceramic Marco Polo. Its convex glaze is printed on the brick surface by screen printing into intermittent convex glaze, fired and then polished, the effect is even more unique.
3. From a technical point of view, there are currently two main production processes for full polished glaze. One is the process used by some companies that originally produced glass-ceramics. In the process of printing and then glazing, the transparent glaze on the surface is thicker, so the three-dimensional effect is stronger, the transparency is better, and it is easy to polish; in addition, because the glaze is thicker, it is easy to throw. The other is a process used by the original manufacturer of antique tiles, that is, both the underglaze pattern and the surface frit are printed on. This process has high fidelity and low cost, but it is very difficult to polish the glaze. Easy to show up.
As a brand-new production process, full polished glaze is perfected in continuous development and testing, regardless of material, equipment or technical aspects, such as wear, dirt absorption, and bottom exposure.
Disadvantages:
1. Low penetration rate, technical requirements, high quality, difficult to guarantee
2. Process equipment for polishing glazed tiles in the past It is not very mature, and there are still few mass-produced products in China. This kind of product has appeared in the world for many years, especially in Spain, Italy, etc., but it has not been widely used, mainly due to technical obstacles and not much comparative advantage (compared with polished tiles).
3. If the glaze is too thick (above 1mm), it will easily produce a lot of bubbles during firing, which will make the product poor in anti-fouling ability and loss of gloss after being thrown. If the glaze layer is too thin, the glazed tiles will always be deformed, and the phenomenon of missing polishing or partial exposure of the bottom may easily occur during polishing. Therefore, in mass production, product quality is difficult to guarantee, and high-quality products are difficult to stabilize.
