CS 5 Flashcards
The flux used in the flux process is a solid material that, when molten,
dissolves other materials
The crucibles that work best for flux growth are made of
Platinum
A laboratory-created gem with essentially the same chemical composition, crystal structure, and properties as its natural counterpart is a(n)
Synthetic
Which process uses a heating unit that passes over a rotating solid rod of chemicals until it forms a synthetic crystal?
Floating Zone
Synthetic turquoise is most likely produced by which process?
Ceramic
Which process involves heating finely ground powder, sometimes under pressure, to produce a fine-grained solid material?
Ceramic
Which synthetic process developed rapidly due to laser research in the 1960s?
Pulling
The two main types of processes for synthetic gem production are melt and
Solution
Which process dissolves nutrients in chemicals to form synthetic crystals?
Flux Growth
Synthetic opal is grown using microscopic silica spheres that are produced by
