What is the maximum temperature that plaster of paris should be dipped in water?

60-65F
70-75F
75-80F
80-85F

The correct answer is: 70-75F

Plaster of Paris is a type of gypsum plaster that is commonly used in orthopedic applications, particularly for making casts and molds. The temperature of the water in which Plaster of Paris is mixed or dipped is crucial for its setting characteristics. The correct range of 70-75°F is optimal because it facilitates an effective and thorough mixing process without accelerating the setting time too quickly. High temperatures can cause the plaster to set too rapidly, leading to a potential for incomplete mixing and weak structural integrity. Conversely, dipping in water that is too cold can slow down the setting process, resulting in a longer time before the plaster sets adequately. Maintaining a temperature within the 70-75°F range ensures that the plaster remains workable enough for applications while still promoting a strong and stable final product. Thus, dipping at this temperature range supports the best performance of the material in orthopedic contexts.
