Correct answer: C. Shape and size of particle
- A. Rate of arriving at firing temperature
- B. Uniformity of particle size
- C. Shape and size of particle
- D. Type of investment used
Explanation
The shape and size of porcelain particles determine how closely they pack during condensation and how much pore space is lost as firing causes shrinkage. Particle-size uniformity also matters, but it is part of the broader particle-size and shape factor.
