What should be done to zinc ornaments, handles, and trim before loading them into the retort?

Before loading zinc ornaments, handles, and trim into the retort, they should be removed. This is essential because zinc has a lower melting point compared to the materials typically used in caskets, like steel or bronze. If zinc items are left in the retort during the cremation process, they can melt and potentially contaminate the remains and affect the cremation equipment.

Removal not only ensures a cleaner cremation process but also preserves the integrity of the cremated remains. Moreover, proper handling of these components aligns with industry best practices and regulations that govern cremation processes, ensuring the respectful treatment of the deceased and their belongings.

Cleaning, painting, or storing separately, while potentially valid considerations in different contexts, do not address the critical issue of preventing contamination during cremation.
