Across
  1. 1. is added to obercomethe hydrophobicity of the wax pattern
  2. 4. regulates heat transfer through the investment material
  3. 6. too rapid heating of the investment during wax elimination may lead to
  4. 7. act as a reservoir for the molten alloy
  5. 8. best timing for investing the wax pattern
Down
  1. 2. one of the causes of the shrinkge spot porosity
  2. 3. short sprue can lead to
  3. 5. melt as the same rate as the wax pattern
  4. 6. is the 2nd step in casting procedure
  5. 9. occur when the sprue is attached 90 degrees to the wax pattern
