Cleaning a Fresh Skull: A Comprehensive Guide for Taxidermists

Taxidermists often deal with skulls, which require meticulous cleaning to preserve their beauty and integrity. While there are various methods for cleaning fresh skulls, using dermestid beetles or boiling water are popular techniques. This article will explore these methods in detail, including safety precautions and tips for success.

Preparation and Safety Precautions

Before you begin the cleaning process, it is essential to take the necessary safety precautions. Put on rubber gloves to protect your hands from any potential contaminants. When handling brain tissue, especially that of ungulates, exercise great care, as it may be carrying infectious agents such as prions. It's crucial to determine the cause of the animal's death accurately to avoid overlooking any other contributing factors.

Always avoid boiling skulls in your residence, as it can produce an unpleasant and intense odor. For larger skulls, boiling is a viable option. For smaller, intricate parts, dermestid beetles are more effective. Be advised, dermestid beetles are beneficial for cleaning, but they should not be used in a domestic setting without proper containment.

Boiling Method for Large Skulls

To prepare for boiling, remove the skin from the skull and pull off any pieces of meat such as the tongue and eyes. Place the skull in a pot of boiling water without submerging the horns. Use butcher’s twine and a wooden spoon as supports to ensure even boiling and prevent the skull from touching the bottom of the pot. Allow it to boil for about an hour or until the bone is sufficiently hardened. Avoid boiling for too long to prevent the bone from softening.

After boiling, carefully scrape off any remaining tissue using a barbecue skewer or a similar tool. This step can be challenging, especially in the brain cavity. If you have access to a dermestid beetle colony, place the skull near it. Wire it to a cinder block to prevent it from being moved by other insects or animals.

Allow the skull to sit near the colony for a couple of days, and the beetles should have stripped most of the remaining tissue. If the skull is not satisfactory, wait a bit longer until the beetles complete their work. Ensure that the insect colony is properly contained, as dermestid beetles can be invasive in households.

Ant Colony Method for Smaller Skulls

For smaller, intricate skulls, using an ant colony can be more feasible. Place the skull near a convenient ant hill and wire it to a cinder block to keep it in place. This method is particularly useful for cleaning hard-to-reach areas, such as the brain cavity and nasal passages.

Ants will work on the skull for a few days, gradually stripping away any remaining tissue. It is crucial to monitor the process and ensure that the skull is thoroughly cleaned. If the ants do not complete the task, wait a bit longer before checking again. By this time, the skull should be mostly free of any remaining tissue.

Final Whitening and Cleaning

Once the skull is free of tissue, it’s time to whiten it. You can purchase hair lightener peroxide from a store and use it as a whitener. Choose the creme type, as it stays on the bone better, especially on the non-horn areas. The peroxide will help degrease the bone and bleach it to a lighter shade. Apply the whitener cream and follow the instructions on the box for the recommended time. Rinse the skull thoroughly after the treatment to remove any residue.

If the skull is not sufficiently white, you can repeat the whitening process. Be careful not to leave the peroxide on for too long, as it can damage the bone. An old toothbrush can help you remove any remaining bits of flesh that the ants might have missed. These bits will be flaky and should come off easily once the skull is sufficiently clean.

This comprehensive cleaning process ensures that the skull is ready for taxidermy work. Taxidermists can now proceed with mounting or preserving the skull for display or other creative uses. Though the process may seem daunting, with the right tools and techniques, any taxidermist can achieve excellent results.

Note: Always handle the skull with care and follow safety guidelines to avoid any potential health risks.

Useful Tips:

Wear rubber gloves when handling the skull and brain tissue. Use a wooden spoon and butcher’s twine for support when boiling the skull. Ensure the dermestid beetle colony or ant hill is properly contained to avoid contamination. Follow the instructions on the peroxide box for the recommended whitening time.

Taxidermy involves meticulous attention to detail and patience. By following these steps, you can achieve a clean and aesthetically pleasing skull for your projects.
