Which preparation step is NOT typically involved in readying a body for public viewing?

The preparation step that is not typically involved in readying a body for public viewing is cremation. Cremation is a process that involves the reduction of a body to ash and bone through combustion. This step does not allow for any viewing, as the body is disposed of instead of being prepared for the public to pay respects.

In contrast, embalming, dressing, and cosmetic application are all processes that are commonly performed prior to a funeral service or public viewing. Embalming preserves the body, allowing it to be displayed for a longer period of time while also having a positive effect on the appearance. Dressing involves placing clothing on the deceased, which is crucial for ensuring the individual is presented in a respectful and dignified manner. Cosmetic application enhances the appearance of the deceased, helping to create a more lifelike appearance for mourners and making the viewing experience more comforting for friends and family.

Thus, cremation stands apart from these steps as it does not facilitate a viewing but instead pertains to the final disposition of the body.
