01 What happened after the wax model melted inside the clay coating in the lost-wax technique?
Answer and explanation
Correct answer: D. Molten metal was poured into the empty space
Explanation: The lost-wax technique works by replacing a temporary wax form with metal. First, the wax model is enclosed in clay and heated so that the wax melts and escapes, leaving a cavity. Molten metal is then poured into that cavity; after cooling, the clay mould is broken to release the object. Therefore option D is correct, while the other choices do not describe the casting sequence.
