The document discusses different types of wax used in funeral services, including their characteristics and uses. There are firm, medium, and soft waxes. Firm wax is used to fill large cavities and model facial features. Medium wax is softer and used for more shallow restorations. Soft wax can be applied in a thin layer for minor abrasions. Different waxes are suited for various reconstruction needs depending on environmental temperature and the depth of work required. Cosmetics may be applied under, mixed with, or over wax to achieve natural skin tones.
