Let's see how this glass is made today

First of all, let's look at the raw materials needed to make glasses, mainly quartz sand, soda ash and limestone.

Quartz sand comes from quartz stone, is a natural mineral, after grinding, washing and processing like the sand on the beach after the glass factory home.
I want the thick stuff on top to be this fine

Soda ash is used to eliminate air bubbles in the glass liquid when melting glass. Soda ash is one of the commonly used clarifying agents, and its dosage is about 1% of the glass melt.

In addition, there are some micro materials that determine the quality of the glass, and the production process of various brands and factories is different.

When the raw materials are ready, they are ready to be sent for processing.

(1) Mix feed
All raw materials are mixed and fed evenly according to the corresponding proportion, and then sent to the kiln through the conveyor belt.

(2) Molten material
The raw material is melted in a kiln at a high temperature of approximately 2300 ° F (1260 ° C).

(3) Cutting material
After melting, the high-temperature glass liquid is transported to the forming machine through the feed channel, and then transported to the mold through the cutting material.

(4) Extrusion molding
After cutting the material, the high temperature glass liquid forms a preliminary shape after the combination of the forming machine and the mold, and then it is treated by the hot explosion or cold cutting.

(5) Annealing
The extruded glass is passed through a large and long iron box, where the temperature is gradually lowered to remove stress from the glass.
The purpose of this is because the glass has been in a high temperature state during the processing process, if this treatment is not carried out, the glass is very easy to self-explode at room temperature or break in use.

For example, the sugar water cans we ate as children are often used to drink water, and some bottles "explode" or "fall off" when they are hot and cold. The annealing step is very important for the quality of the glass.
Heat and then fill with cold water

(6) Inspection
The finished glass is finished after passing the manual inspection

For the high-end glassware is the worker master with the mouth blown into, this cheek look distressed
After blowing can be personalized customization, are craftsmen ah.

Find a pull into the shape of a swan, master hand really clever, really beautiful!
