摘要：
An apparatus for optical measurement of a liquid or molten material, which has: a transparent container which has a bottom face and is capable of containing a to-be-measured material therein, with the bottom face at least having a flat face and being transparent; and an optical device that irradiates a light to the bottom face of the container and that detects and measures a reflected light from the bottom face; and a method for optically measuring a liquid or molten material using the apparatus.
