What is the primary purpose of using flux in the casting process?

Show Answers

Eliminate oxides that develop on the gold alloyReduce the melting temperatureSubstitute for casting waxAccelerate the burnout phase

Explanation

Flux is primarily applied to remove oxide layers that form on the surface of the gold alloy during casting, ensuring a cleaner and more precise final product. Other options such as lowering melting point, replacing wax, or speeding burnout are not the main functions of flux.
