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