Changing water temperature is the best way to alter the setting time of alginate.If additional time is needed for the procedure,cooler water will increase the setting time.Warmer water will shorten the setting time of the procedure.
Changing the water-to-powder ratio will change the properties of the material and is not recommended.
Adding a colloidal material to the alginate will retard setting but is not recommended.
