What is the difference between frosted and opalescent glass?

Frosted glass has a mechanically or chemically roughened surface that diffuses light and creates a matte texture. Opalescent glass contains ingredients that cause it to milky-blue or fire-like appearance when light passes through. Many decorative pieces combine both effects within a single moulded design to enhance sculptural depth.
