Tea making steps:

  In 1884, Otto Schott, which owned the advanced glass factory in Europe at that time, successfully developed a kind of high temperature resistant borosilicate glass, relying on its closer molecular structure than traditional soda lime glass, this new type of glass not only has smaller thickness and lighter texture, but also has better firmness and excellent heat resistance. Due to the high initial cost, it is only used for European royal dining utensils. After years of development and technological improvement, borosilicate heat-resistant glass has been gradually popularized into people's daily life.

                                        Borosilicate glass has the following advantages:

 1. The material is fine and does not absorb water.

 2. Excellent acid, alkali and water resistance, especially suitable for making tea and coffee.

 3. Available from the above two articles, High Borosilicate glass products are easy to clean, not easy to stain, and still bright and clean as new after long-term use.

 4. High hardness, wear-resistant, and can be cleaned by dishwasher.

 5. It does not contain any harmful substances to human body.

 6. It can be used in microwave ovens, heating is not hot, absorbing little microwave, saving electricity and energy. It can also be used for refrigerator freezing and electric ceramic stove heating.

 7. It has the characteristics of resistance to sudden cold, acute heat, impact resistance, not easy to crack, and can withstand the instantaneous temperature difference of-30~150 ℃. 8. Transparency is as high as 92%, crystal clear and transparent, and drinking has high ornamental value.

What is borosilicate glass?

  Borosilicate is a special glass with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability.

  Glass material, resistant to instant hot and cold-30 ° ~ 150 °, has been widely used in Germany and America and other countries.

High Borosilicate Glass Manufacturing Process?

High-quality borosilicate material, with high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability,

  it is made by complicated processes such as hand blowing cup body, back cover, tearing, welding, etc.
