Applying the Hallmark
The hallmark can be applied to an item of precious metal in different ways depending on the number of articles, the stage of manufacture or the size and construction of the item.
Hand marking does exactly as the name suggests and the hallmark is stamped by hand with a punch and a hammer. This technique is ideal for small batches or large single pieces. Before the introduction of laser marking this was the only means of marking delicate items. The Assay Office Scotland led the field in this type of marking and those specialist skills are retained to this day.
Machine marking still involves a punch being applied to the article like hand marking only the hallmarking punch is pressed or struck into the item using hydro-pneumatic presses. This technique is ideal for larger batches of like product and remains the quickest and most cost effective means of applying a hallmark.
Laser marking does not require any physical contact with the item. The mark is applied by a very precise computer controlled laser engraving machine. Laser hallmarking is ideal for hallmarking hollow or delicate items as well as for applying marks in an area where it would be otherwise impossible to strike a mark.
