Various materials for attachment such as solders can be applied on articles of precious metals. They can be used to the extent that attaching requires. Only such precious metal that is intended to be marked can be used to reinforce, fill or increase the weight of an article of precious metals.
An exception to the above-stated rule applies to pieces of cutlery, candlesticks and similar items. When attaching or filling a handle or a stand on an article made of sheeted precious metals, a precious metal with a fineness lower than that indicated by the fineness mark, base metal or other material can be used for certain justified reasons. In this case, the manufacturer should provide written justified grounds with a description of the structure and materials used in the product. The written product description for consumers may be readily available at the point of sale.
