What consistency wax should be used for a significant open wound during initial application?

The optimal choice for a significant open wound during initial application is a firm wound filler. This type of wax is specifically designed to provide a solid structure that can fill larger defects or open wounds effectively. Its firm consistency allows it to hold its shape and provide support to the surrounding tissues, which is crucial for stabilizing the area and preventing further damage.

Wound fillers often contain properties that help to adhere well to the surrounding skin, ensuring that they remain in place throughout the embalming process. Additionally, a firm texture allows for better sculpting and shaping, which is essential when attempting to create a natural appearance for the deceased, especially in visible areas.

In contrast, other options like surface wax, liquid seal, and putty wax have specific uses that may not be suitable for significant open wounds. Surface wax is typically used for superficial corrections and not for filling deeper wounds. Liquid seal is designed for creating barriers or protective layers rather than providing structural support, while putty wax, which is often used for smaller repairs or details, may not offer the firmness needed for a significant wound.
