For this particular alginate the instructions state that two scoops of alginate powder are needed to one full measure of water.

The components needed: - Alginate powder and measuring scoop, rubber mixing bowl and water measurer, spatula (a plastic flexible spatula may also be used) and the appropriate impression tray.

Two scoops of alginate powder are added to the rubber mixing bowl.

One full measure of tepid water is added to the rubber mixing bowl.

The alginate powder and tepid water are then gradually mixed together using a spatula. Care should be taken to ensure all the powder granules are incorporated. The spatula is used in such a way as to smooth the alginate mixture against the rubber bowl and release any air bubbles that may have become trapped in the alginate mixture during the initial mixing stage. This is continued until a silk smooth and glossy consistency, free of air bubbles is achieved.

The silk smooth alginate mixture prior to application to the impression tray.

The alginate mixture is applied to the impression tray as shown. N.B. The impression tray should not be over loaded with alginate.

The alginate impression material prior to being inserted in the patient's mouth. N.B. The posterior of the impression tray is not over loaded with alginate. This will prevent the excess alginate impression material over extending along the soft palate.
