Cutlery made of pure silver is an expression of elevated dining culture. The glossiness of the silver conveys a high value and is a daily delight. If used regularly, silverware will not tarnish. Pure silver without alloy is not suitable for making cutlery, as it is too soft and not dimensionally stable.
That is why copper is incorporated for hardening. Therefore silverware is labelled with a stamp figure indicating the fineness of the pure silver. Thus, the stamp figure 800 or 925 means that in relation to 1,000 g there are 800 or 925 g of pure silver contained in the alloy. 925-silver is called sterling silver.
For tempering and hardening the surface, all WMF pure silver models have been hard silver-plated in addition.
 Pure silver cutleries are marked by a half-moon (as the symbol for silver) and a crown.
