Flint glass is usually composed of either lead or potassium silicate. This blend creates a relatively high refractive index and a high degree of light dispering power compared to other types of glass. As a result, this blend of glass is characterized by its brilliance and luminosity. This property makes flint glass especially desirable in the production of lenses, optical instruments, prisms, and ornamental glassware. The name "flint" is derived from the mid 17th century process of grinding flint stones into a fine powder from which silica was obtained.
Flint glass is also known as soda lime glass. It has a lower melting point, chemical resistance, and expansion rate than does borosilicate glass. The most commonly used diameters of flint tubing are included in this assortment that totals a little over 2 pounds. All pieces are 24" in length, and 36 pieces are included, in various diameters (see Features below).
Every chemistry lab should have some flint glass tubing. Use it to connect flasks together by heating the glass and bending it to the desired angle. Use in tandem with our Glass Tubing Cutter to cut the tubing down to your desired length.
The assortment includes 12 pcs. of 5mm OD, 11 pcs. of 6mm OD, 4 pcs. of 7mm OD, 3 pcs. of 8mm OD, 3 pcs. of 10mm OD, and 3 pcs. of 12mm OD. (OD = Outer Diameter)
