– The present investigation has shown that the surface of gold alloys cast in both a new and probably improved investment and in two commercial gypsum‐bonded investments fulfills all conventional clinical requirements as regards retention and precision of the cemented restorations and easy polish ability. With a view to retention the sometimes slightly rougher surfaces of castings in the new investment are advantageous.
