To effectively preserve a bird skull and ensure its longevity after cleaning and bleaching, the most recommended method involves applying a specific lacquer mixture.
The Preservation Process for Bird Skulls
Preserving a bird skull is the final crucial step after it has been thoroughly cleaned and bleached. This process not only protects the delicate bone structure but also gives it a finished, lasting appearance.
Essential Preparations
Before preservation, it's vital that the bird skull is completely free of any organic material and thoroughly bleached for aesthetic appeal. Most importantly, the skull must be completely dry to allow the preservation mixture to adhere properly and prevent any future decay.
Crafting the Preservation Mixture
The key to durable preservation lies in a specific blend of materials. You will need clear lacquer and lacquer thinner.
| Component | Proportion | Purpose |
|---|---|---|
| Clear Lacquer | ½ part | Provides a protective, durable coating that seals the bone. |
| Lacquer Thinner | ½ part | Ensures proper consistency for even application and optimal penetration. |
This mixture of ½ clear lacquer and ½ lacquer thinner creates an ideal sealant that effectively penetrates and coats the bone without leaving an overly thick or unnatural film.
Application Techniques
Once your mixture is ready and the skull is thoroughly dry, you have two primary methods for application:
- Complete Immersion: For a thorough and even coating, completely immerse the dry bird skull into the lacquer mixture. This ensures that every intricate crevice and surface is sealed. Carefully remove the skull and allow any excess mixture to drip off.
- Brushing On: Alternatively, you can use a fine brush to carefully apply the mixture to all surfaces of the skull. This method offers more control, especially for delicate or intricate specimens. Ensure an even coat and avoid pooling in depressions.
Regardless of the method chosen, always work in a well-ventilated area due to the fumes from lacquer and thinner. Allow the skull to dry completely, which may take several hours. For added protection and a more robust finish, a second coat can be applied once the first is dry.
Display and Care
Once preserved, bird skulls are quite durable. They should be displayed in a stable environment, away from direct sunlight and extreme temperature fluctuations, to prevent any long-term degradation of the finish. Regular light dusting is usually sufficient for maintenance.
