[26-1818] I read that the number sometimes stamped on a silverplate object (like a "25" on a little spoon) is showing how tick is the "plating". But I wondered first if is that right and second what range of numbers are telling if it is a poor, regular, good or exceptional object. Thanks for your help. IP: Logged |

Actually, I think it means the grammage of silver used to plate per dozen pieces, although, the more grams of silver used, it stands to reason that the plating would be thicker. For example, if a Christofle fork or spoon says "100", I believe it indicates that 100 grams of silver were used to plate 1 dozen forks or spoons in that given batch. I also think that French manufacturers (Christofle being the first) took this method of marking from the Germans, who began doing this in the mid 19th century. Anyone, please correct me if I am wrong on this... IP: Logged |

It depends on the country of origin of the silver plated object. In most countries such numbers do not mean very much and each maker may use whatever markings they like to give the buyer the impression that the silver plating is worth paying for. For such silver plated objects numbers or words only indicate the thickness for objects made by that particular company relative to other objects made by that company, and there is no relationship with objects made by any other company. In a few countries, such as France, there are standards that are supposed to be enforced and I am sure the better makers comply with them. For example in France in order to use certain markings on silver plate the thickness must be guaranteed at time of manufacture. A typical good quality standard would be 100 grams which would be 42 microns of silver plating. A high quality standard would be 150 grams which would be 63 microns of silver plating. The grams of silver is meant to represent the amount of silver it would take to plate 24 spoons or forks. As you can see, the amount of silver in even the highest quality plating is quite small.

In the US there is no legal standard that I am aware of. The Meriden Brittania Company had a system that measured how many ounces were on 2 dozen pieces. Other companies used other standards, most of which were more for advertizing than anything else. Deep Silver, Reinforced Plate, Quadruple Plate, Quintuple Plate; all of which do not have settled meanings. I go by the general quality of the company's production as I have experienced it.

If you use the Search function, you will find a good amount of information about silver plating standards, in particular about Christofle. IP: Logged |

The French use markings to indicate the thickness of the plating. On an object with a heavy plating of 100 grams which indicates a thickness of 43 microns of silver plate keep in mind that this is very little silver. It takes 1000 microns to make just 1 millimeter of thickness. IP: Logged |
