The product adopts 3.3 high borosilicate glass pipes and rods, and the raw material is a special glass material with low expansion rate (thermal expansion coefficient: (0-300 ℃) 3.3 ± 0.1x10-6K-1), high temperature resistance (softening point of 820 ℃, high thermal stability, heat resistance temperature difference greater than 270 ℃), high strength, high hardness, high transmittance, and high chemical stability. It is made by hand blowing. The glass handicraft is crystal clear, novel in style, and unique in design. Economic and environmental protection.
Purchase instructions; There are slight differences in the size, weight, and thickness of pure handmade products, with some leaving mold marks and bubbles, which are normal imagination and not defects.
