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