All products are made of 3.3 high borosilicate glass tubes and rods. This raw material is a special glass material with low expansion rate (thermal expansion coefficient: (0~**0℃) 3.3±0.1x***6K*1), high temperature resistance (softening point **0℃, high thermal stability, heat-resistant temperature difference greater than **0℃), high strength, high hardness, high light transmittance and high chemical stability, which is hand-blown. Glass crafts are crystal clear, with novel styles and unique shapes. They are economical and environmentally friendly. The main products include glass tea set series, chemical instruments, and crafts. In recent years, newly developed heat-resistant glass products include: glass double-layer cups, heat-resistant glass teapots, high borosilicate glass double-layer cups, heat-resistant glass tea sets, glass candlesticks, glass lanterns, glass oil lamps, glass smoking sets, glass water cups, glass flower holders, glass seasoning bottles, etc.
