2
Place the cloth directly on top of the chuck to reduce slipping while mixing.

Place the glass slab on top of the cloth.

Put a small mound of zinc oxide on one side of the glass slab (off-center).

5
Place your metal spatula, bottle of eugenol and eyedropper on the chuck within easy reach in your workspace.
Mixing Dental Cement

Using the dropper, dispense several drops of eugenol on the center of the slab.

Using the metal spatula, separate a small amount of zinc oxide powder from the mound and push it into the pool of eugenol.
-
8
Use the flat side of your spatula to thoroughly mix the eugenol and powder.

Tips & Warnings
Unused zinc oxide powder can be returned to its original container. Apply the cement to clean, dry surfaces for proper adhesion. Dried cement can be scraped off the glass slab. The desired consistency is a thin paste, similar to frosting or icing (not stiff). If the mixture is stiff, thin the mixture with a drop of eugenol and mix.
Avoid inhaling or breathing the zinc oxide powder. Take care when dispensing eugenol because it stains materials. People with perfume allergies may be sensitive to eugenol.
