Pure gold is slightly reddish yellow in color, [2] but colored gold can come in a variety of different colors by alloying it with different elements.
Gold-filled is a type of composite material. Composites are formed from two or more constituent materials with different properties that, when combined, create a new material with enhanced properties. [1] Gold-filled material is made by bonding a layer of gold alloy to a base metal core (typically brass, but sometimes copper or silver).
The seal-making device is also referred to as the seal matrix or die; the imprint it creates as the seal impression (or, more rarely, the sealing). [1] If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal ; in other cases ink or ...
