Answer:
It is critical from the public's perspective that there is confidence in the claimed purity of any particular item made from precious metals. This confidence is provided by an 'assay' (test and assess) of the precious metal content of that item. It is impossible to tell the precious metal content of any item simply by looking at it. Precious metals such as old, silver, and platinum are too soft to use alone for making jewellery, cutlery and other goods. Quite properly they must be alloyed with base metals (which happen to be cheap) for manufacturing. The assay protects the consumer by ensuring sure that not too much base metal was used. It also safeguards responsible manufacturers by providing an independent assessment of quality and content that in which the public has confidence.
