Glass ball 
 Colored glass ball: colored glass by adding coloring agents refers to the different colors of glass after the show. Is joined with ordinary glass coloring agents, such as adding MnO2 to purple; CoO, Co2O3 firing purple; FeO, K2Cr2O7 firing green; CdS, Fe2O3, SB2S3, burning yellow; AuCl3, Cu2O firing red; CuO, MnO2, CoO, Fe3O4 firing a mixture of black; CaF2, SnO2 firing white. Coloring dose the amount of melting time and melting temperature will affect the firing of different degrees of color depth. Use of colloidal colorants, such as gold, silver, copper, selenium, sulfur, so that very small particles suspended in the vitreous body, so that the glass coloring. In the firing process, no matter what kind of coloring agent are added flux. 
 Colored glass, also known as heat-absorbing glass, to absorb the sun's visible light, reduced the intensity of sunlight, the glass absorbs the sun's rays at the same time its temperature rises, heat up prone to cracking. 
 Colored glass is solid sol. 
 Solid sol: the solid form as a dispersion medium of the sol. 
 . 
 Borosilicate glass: experimental proof of such material and glass particles within the surface water law water resistance test, and some reach a level of HC1, or between one and two edges. Practice has proved that this type of glass and some will appear in use or off-chip failure neutral phenomenon, but this type of glass production in China has been used for many years, this new standard to retain the material glass and provides its B-2O- 3 content should be consistent with 5 - 8% (m / m) requirements, can not clearly define the type of glass called borosilicate glass (glass or neutral), and named it as low borosilicate glass. 
 Soda-lime glass: 
 Quartz: 
 Crystal chemical formula SiO2. Quartz in the nature of the main components of quartz, often contain a small amount of impurities, such as Al2O3, CaO, MgO, etc., it has many types. Ceramics materials are used in vein quartz, quartz sand, quartzite, sandstone, silica, opal, diatomaceous earth, rice shell ash is also rich in SiO2. Often has the appearance of colorless quartz, white, milky white, translucent gray, Mohs hardness of 7, broken glass mask gloss sheen or fat, the proportion varies due to crystal, changes in between 2.22 to 2.65. With ordinary sand, crystal is "with the birth" of a substance. When the time is perfect crystalline silica crystal; silica gel dehydration is agate; solidification colloidal silica water after a opal; silica grains smaller than a few microns, on the formation of chalcedony, flint, sub- Health and quartzite. 
 Non-plastic material of quartz, with clay at high temperatures generated in the crystal mullite porcelain to give high mechanical strength and chemical stability, and can increase the translucent green body, and is a good preparation of white glaze raw materials. 
 Crystal Glass: Crystal glass its called man-made crystal, due to the scarcity of natural crystal and is not easy to mine, can not meet people's needs, man-made crystal glass was born. As the high permeability, can be made into a variety of crafts and greatly favored the world. The scope of this definition is very broad, Venice, the sodium-calcium crystal (Cristallo), Bohemia crystal of calcium and sodium potassium calcium crystal glass (Crystalex) and lead crystal should be included. However, very few people will be in Venice crystallo as crystal glass, largely become a historical term. 
 Crystal ZnO, BaO, PbO, K2O in a single component or the total composition ≥ 10%, density d ≥ 2.45g/cm3, refractive index nD ≥ 1.52 
 Austrian crystal glass will be divided into: 
 (1) Full Crystal (Full Crystal) PbO ≥ 24%; 
 (2) Crystal (Crystal) PbO 10% ~ 24%; 
 (3) Fine Crystal (Fine Crystal) PbO6% ~ 10%. 
 Czech Republic will lead crystal glass is divided into: 
 (1) Full lead crystal glass PbO ≥ 30%; 
 (2) of lead crystal glass PbO ≥ 24%; 
 (3) low-lead crystal glass PbO ≥ 7%. 
 China there is no state and industry standards, habits are divided into: 
 (1) high-lead crystal glass PbO ≥ 30%; 
 (2) of lead crystal glass PbO ≥ 24% 

 Stained Glass: English Name: Stained Glass; colour glass 
 Uses: used in Art items. Be used to make stained glass lampshades and vases and other ornaments, but the word most often and huge windows of the church together. Stained glass windows of the manufacturing process in the Middle Ages Yin Gete-style church building reached its peak. Stained glass windows not only allow light launched into the church, but also provides a decorative and can be used to tell Bible stories.
