Origami-like silver objects made from metal clay with silver powder. Metal clay is a crafting medium consisting of very small particles of metal such as silver, gold, bronze, or copper mixed with an organic binder and water for use in making jewelry, beads and small sculptures. Originating in Japan in 1990, metal clay can be shaped just like ...
A small amount of metal in a crucible (a sort of ceramic pan) next to the mold is heated with a torch. When the metal is molten the arm is released, forcing (by centrifugal force) the metal into the mold. The high forces imposed on the metal overcome the viscosity, resulting in a finely detailed workpiece.
Silversmiths saw or cut specific shapes from sterling and fine silver sheet metal and bar stock; they then use hammers to form the metal over anvils and stakes. Silver is hammered cold (at room temperature). As the metal is hammered, bent, and worked, it 'work-hardens'. Annealing is the heat-treatment used to make the metal soft again. If metal ...
Repoussé (French: ⓘ) or repoussage (ⓘ) is a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing (French: ciselure) or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in ...
Illustration of stepwise bronze casting by the lost-wax method. Lost-wax casting – also called investment casting, precision casting, or cire perdue (French: [siʁ pɛʁdy]; borrowed from French) [1] – is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture.
Silver is known in the chemistry world as a noble metal, which means it is resistant to corrosion, but not completely immune. Whether silver plating or pure silver, the composite of the metal will tarnish when exposed to air and sulfur. Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of ...
