Human: How do I determine the melting point of sugar? Assistant: 
The melting point of sugar is a function of its composition, purity, and moisture content. Generally speaking, the higher the percentage of sucrose (sugar) in the sugar, the lower the melting point. Pure sucrose has a melting point of approximately 340°F (171°C). Moisture content also affects the melting point of sugar as dry sugar will have a higher melting point than moist sugar.
