Crystal Courant, 70mm (there is also a smaller Courant, 50mm)
Used for creating (rubbing with emulsion) pigments. Good for both classic yolk tempera and for the preparation of wax tempera using a special medium. It will also be necessary to purchase a rubbing glass.
As a more budget-friendly option, a special porcelain mortar can be used for well-pounded pigments (and we have almost all of them, except for cinnabar and some Russian pigments).
