Egg Tempera Class at the V&A: the pigments and the grinding
The pigment is ground (see photo) using a glass muller with a ground base which looks rather like a paper weight with a knob on top. Grinding continues until the pigment mix is the consistency of thick cream. The egg tempera mix dries very fast on the grinding plate and it can be scraped down and reused for the next pigment very easily.
