Annealing
The process of softening metal with heat before you work on it For silver the annealing temperature is between 1110-1200F (the melting point of silver is 1635F). The silver should be quenched (or cooled) after annealing when it drops below 930F 
Casting
The process of mass-producing the same item in either the cuttlefish casting process, the lost wax method or a rubber mould.
Chasing
The method of creating lines of a pattern along the surfaces of the metal by using a small steel tool
Doming and swaging
A swage block or a doming block is used to form half-spheres or domes out of the silver.
Forging
Forging is the method of curving, stretching, flattening and shaping the silver by applying force from different directions with different shaped hammers.
Fusing
Joining different parts of the silver by using purely heat and not solder i.e. the metal fuses together.
Inlaying
Lines or shapes can be grooved or cut of the silver and then another metal, wood, stone etc can be laid into the channels or grooves.
"Mandrels"
A tool used for shaping jewelry items. For rings, they are known as "Triblets" or Ring"mandrels" which is a long tapered tool made of steel that is marked in ring sizes from A to Z. (mandrels are used for more than just stretching rings e.g. bezels). The ring "mandral" is sometimes also used for shaping and forming rings.
"Mokume Gane"
A technique whereby the surface of the metal is decorated in such a way as to resemble the grains of a wood. It can be achieved using layers of metals of a different color soldered together.
Pickling
The process of using chemicals to clean the metal after it has been heated. When the silver is heated, oxides appear of the surface which then can be removed by pickling. We use alum although Sulfuric acid is more than effective.
"Repousse"
"Repousse" is the art of working with punches from the back of an item to form lines and shapes to create a 3 dimensional effect from the front.
Reticulation
The art of making veins or fibres, for example a leaf, appear across the silver. Reticulation can be achieved by repeating various heat treatments at different stages.
