What is the proper method when using sulfur casting for a footwear impression in snow?

When employing sulfur casting to capture a footwear impression in snow, it is essential to melt the sulfur at the proper temperature to ensure that it achieves the right consistency for creating a detailed impression. Melting sulfur in an aluminum pot at 115 degrees Celsius is the appropriate method because this temperature is optimal for ensuring the sulfur is liquid enough to flow into the substrate of the impression and fill in all details without being too hot, which could damage the impression.

This specific temperature also helps to ensure the sulfur sets correctly after being poured, allowing for clear and precise documentation of the footwear pattern without introducing the risk of distortion. If sulfur is heated too much beyond this temperature, it can degrade or emit harmful fumes, which can compromise both the safety of the personnel and the quality of the impression. Choosing a lower temperature might result in the sulfur not flowing adequately to capture fine details. Thus, utilizing an optimal melting point not only aids in effective casting but also ensures a safe working environment and integrity of the evidence collected.
