My question is from Precision Investment Casting in chapter Special Casting Techniques of Casting-Forming-Welding I

Answer 1

The correct option is (a) True

To elaborate: In the process of stuccoing, dry refractory grains such as zircon or silica are stuccoed on the liquid ceramic coating. A small shell is formed around the pattern, which is to be cured and then the process of dipping and stuccoing is continued with ceramic slurries to achieve a well desired thickness of the mould.
