Material and classification of glass packaging container

Material and classification of glass packaging container
Glass is a transparent substance of one or more types of citrates, which can be classified according to their raw materials, ingredients, chemical composition, color, etc.
According to its raw material manufacturing can be divided into:
1. Lime soda glass is the most common glass used for making bottles, cups, lampshades and low-cost presses.
2. Lead-containing glass, which can be made into crystal glass such as bright and clean, which is the most suitable for tableware and decorations.
3. Color glass and various metal oxides can be added to the glass to obtain various colors of glass.
For example: cobalt oxide is used to make blue glass, and manganese dioxide makes the glass purple.
may be divided into:
 1. Single glass:
 1. Sodium Silicate
2. Potassium Silicate
3. Lead Silicate
Second, combined glass:
1. Lead Alkali Glass
Flint Glass
Crystal Glass
Hollow Ware Glass
 2. Soda Lime Glass
Crown Glass
Sheet Glass
Plate Glass
Bottle Glass
3. Potash Lime Glass
Hard Glass (Bohemia Glass)
 4. Soda Barium Glass
Pressed Glass
5. Boro- Silicate Glass
Optical Glass
Enamel (Enamel)
jade(Gems)
 is divided into:
First, soda lime glass (lime glass or soda glass) (lead-free crystal glass)
Na2O-CaO-SiO2 series glass, sodium oxide (Na2O), calcium oxide (CaO), silicon oxide (SiO2) as the main components.
 Second, potassium glass (lead-free crystal glass)
K2O-CaO-SiO2 glass, K2O, CaO and SiO2 as the main components.
3. Lead glass
1. Semi-lead crystal glass
R2O-CaO-PbO-SiO2 series glass, R2O, CaO, lead oxide (PbO) and SiO2 as the main components, PbO16% or less.
2. All-lead crystal glass
R2O-PbO-SiO2 series glass, R2O, PbO and SiO2 as the main components, PbO17-23%.
3. High-lead crystal glass
R2O-PbO-SiO2 series glass, R2O, PbO and SiO2 as the main components, PbO24% or more.
Fourth, borosilicate glass (heat-resistant crystal glass)
R2O-B2O3- SiO2 series glass, R2O, PbO, B2O3 and SiO2 as the main components, the thermal expansion coefficient is below.
 is divided into:
1. Colorless transparent glass
Second, stained glass
 3. Emulsified glass
1. Opal glass/jade glass
2. Alabast glass (half-jade glass)
