Filigree

Primarily refers to fine, ornate metalwork (mainly in gold, silver, or copper), that is intricately patterned and used as ornamentation or embellishment, particularly in fine jewelry making. More broadly, the term can refer to any ornamental openwork that is delicate or fine that resembles a metal filigree in its pattern, but in other mediums.

Porcelain

Porcelain is a hard, non-porous pottery. Porcelain is white, has a fine-grained body and usually translucent. Porcelain differs from earthenware in that earthenware is porous, opaque and coarse. True porcelain is made of kaolin or china clay.
