fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely
What is the refractive index of white fused alumina compared with that of glass?
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
