What is the initial setting time for plaster?

The initial setting time for plaster, particularly dental plaster, is generally recognized to be around 10 minutes. This time frame indicates how long it takes for the plaster to begin hardening after mixing, making it critical for dental professionals to work efficiently during this period. Understanding the setting time is essential for proper application in dental casts as it influences the accuracy and quality of the impressions taken. The process of setting is affected by factors such as water-to-powder ratio, temperature, and humidity, but the standard initial setting time serves as a guideline for practitioners in dental settings.
