The correct answer is: a) Fine silver wires crafted into intricate designs.
Silver filigree is a delicate art form that involves the use of fine silver wires to create intricate designs. The wires are twisted, coiled, and woven together to create a variety of patterns, which are then often inlaid with precious stones or other materials. Silver filigree is a very time-consuming and labor-intensive process, and it requires a high level of skill and artistry.
Embossing is a process of creating raised designs on metal sheets by hammering or pressing them with a die. Enameling is a process of applying colored glass to metal surfaces, and inlay is a process of inserting pieces of one material into another. Casting is a process of pouring molten metal into a mold to create a desired shape.
While all of these processes can be used to create beautiful objects, they are not the same as silver filigree. Silver filigree is a specific type of art form that involves the use of fine silver wires to create intricate designs.
