glass is divided into many kinds according to its different production processes. The common ones used in furniture production are flat glass, float glass, frosted glass, patterned glass, colored glass, etc

(1) flat glass

the production of flat glass has always followed the "lead up method", so the glass produced by this process generally has ribs inside, ripples on the surface, and the object image will deform through the glass, so it must also be polished by mechanical grinding. Flat glass is not widely used in furniture, only in cabinet doors and lying boards with relatively low prices

(2) float glass

the production process of float glass is more advanced than flat glass. Generally, the surface is flat, very bright and clean, without corrugated ribs and waves. Float glass is widely used in furniture. In addition to traditional cabinet doors and lying boards, it is also often used to make tabletops, tea tables and some furniture with pure glass structure. When making panels and structural materials, the thickness is generally between 8mm-12mm, and the edges of this glass need to be carefully cut and ground

(3) frosted glass

also known as ground glass, uses mechanical sandblasting, manual grinding and other methods to treat the surface of flat glass into a uniform rough surface. After the surface is rough, diffuse light is generated, which only has light transmittance and cannot be seen through. Now this process is often used to make some decorative effects, such as adding a frosted frame on the edge of the glass, or sandblasting on the surface of the glass to form various patterns. This method is often used in tabletops, tea tables and other places, and can receive good decorative effects

(4) patterned glass

patterned glass is to engrave, print and other colorless parts of the glass according to the design pattern, so that the surface has various patterns and different textures. According to the processing method, it can be divided into embossed glass, sprayed glass and engraved glass. Patterned glass also played a decorative role, and began to be popular in China

(5) colored glass

colored glass is divided into transparent and opaque. Transparent colored glass is to add a certain amount of metal oxide to the raw materials to make the glass colored; Opaque glass is made by baking one side of flat glass with a certain shape, sprayed with colored glaze. Colored glass has a variety of colors, and flower shaped decorations can be processed and customized according to different needs

in addition to the above glass varieties commonly used in furniture, the glass used in furniture also needs to be toughened, especially on the desktop, coffee table, etc., because its strength is 3-5 times greater than that of untreated glass, and it has good impact resistance, bending resistance, rapid cooling and rapid heating resistance. When the glass is broken, it will break into blunt small pieces, which will not hurt people

when selecting decorative glass, pay attention to the following points:

1 Moderate thickness. Because the glass used on the table and several sides often bears the impact of certain weight and gravity, it must have sufficient thickness. Generally, the thickness of the glass used in these parts can be less than 8mm. The larger the size, the higher the thickness

2. Exquisite processing. The glass used as table top, several sides, lying board, cabinet door, etc. must be polished to avoid injury. Some decorative edges must also be mechanically polished. These edges should be smooth, flat and straight. Only in this way can we receive exquisite decorative effects

3. Less natural defects. In the production process of glass, there will inevitably be various defects, the main defects are bubbles, scratches, sand, pimples, raceways and so on. Therefore, the finished products of glass are also divided into various grades. Those used for furniture countertop ornaments should be a special choice, and the ingredients of their natural defects should also be very few. Any glass with more than one defect found in the selection process is of lower grade

4. No cracks. Cracks and chippings often occur in the cutting process of glass. If they are not eliminated by edging, defects will be left. Moreover, some deep cracks also leave hidden dangers of future stress and fragmentation, which should be carefully avoided in selection

5. Confirm whether it is a qualified product produced by a regular manufacturer
