About
Borosilicate Glass Rod 33COE is a low-expansion borosilicate glass with a coefficient of expansion of 33 x 10⁻⁷ per °C. Manufactured through controlled melting and forming processes using high-purity silica and boron oxide, these rods exhibit exceptional thermal shock resistance and optical clarity. The material is produced by specialized glass manufacturers who maintain precise temperature controls during formation. Primary applications include lampworking, scientific glassblowing, jewelry making, and artistic glass sculpture. Key properties include high chemical durability, low thermal expansion, excellent workability when heated, and compatibility with other 33COE glasses for seamless joining. Makers purchase these rods for their predictable working characteristics, minimal stress development during cooling, and ability to create complex forms without cracking. Available in various diameters, the material offers consistent quality for both professional glassworkers and hobbyist artisans requiring reliable thermal properties.
