Did You Know?
1. Did you know that ancient Egyptians were among the first to develop techniques for tanning animal hides? They used a combination of salt and plant extracts like tannin-rich tree barks to preserve and treat the hides for taxidermy purposes.
2. The term “tanning” for the process of treating hides actually comes from the use of tannins in the tanning process. Tannins are the natural chemical compounds found in tree barks and leaves that bind to proteins in the hide, making it more resistant to decay.
3. Before the invention of synthetic tanning agents, some indigenous tribes in North America had a unique technique for tanning hides. They would chew on animal brains and use the saliva, which contains enzymes, to break down the fat and connective tissue in the hide, making it easier to tan.
4. A surprising and little-known fact is that urine was historically used in the tanning process. Urine from humans as well as other animals, such as dogs, was collected and used as a source of ammonia. The ammonia in urine helps to soften the hides and remove hair and flesh.
5. While most people associate tanning with preserving animal hides, tannins are also used in the tanning of leather for fashion purposes. The leather used to make high-quality handbags, shoes, and other luxury goods often undergoes a tanning process using tannins derived from tree barks, contributing to their durability and rich appearance.
Fleshing The Hide
Tanning a hide for taxidermy requires careful and meticulous preparation to ensure the preservation of the animal skin. The first step in this process is fleshing the hide. Fleshing involves removing any excess flesh, fat, and muscle tissue from the hide to ensure the tanning solution can penetrate evenly.
To begin, lay the hide on a clean and flat surface. Using a fleshing knife or a sharp blade, carefully scrape off the flesh and fat from the hide. It is important to be gentle during this process to avoid damaging the skin. Work methodically, starting from one end of the hide and moving towards the other, ensuring all areas are thoroughly fleshed.
Once the fleshing is complete, inspect the hide for any remaining tissue or fat. It is crucial to remove as much as possible, as any leftover organic matter can lead to decay and spoilage during the tanning process. Take your time and be thorough in this step to achieve the best results.
Salting To Remove Moisture
After fleshing, the next step in tanning a hide for taxidermy is salting. Salting helps remove moisture from the hide, preventing bacterial growth and decay. It also acts as a preservative, keeping the hide in a stable condition until the tanning process can be completed.
To salt the hide:
- Sprinkle a generous amount of non-iodized salt on both sides of the skin, thoroughly covering the entire surface.
- Pay special attention to areas with folds or creases, as moisture tends to accumulate in these regions.
Fold the hide in half, with the flesh side facing inwards, to prevent it from drying out too quickly. Place the folded hide in a cool, dry area and allow it to sit for at least 24 hours. During this time, the salt will draw out moisture, effectively preserving the hide.
After the initial salting period, carefully remove any excess salt from the hide using a brush or a soft cloth. The hide is now ready for further tanning processes.
Rehydrating With Tanning Oil Or Solution
Once the hide has been properly salted and excess salt has been removed, it is important to rehydrate the skin before moving on to the tanning process. Rehydration helps restore flexibility and pliability to the hide, ensuring it can be properly stretched and tanned.
There are two options for rehydrating the hide:
- Tanning oil: a mixture of oils that provide moisture and suppleness to the skin. It is commonly used for smaller hides or when a softer finished product is desired.
- Rehydration solution: a blend of water and specific chemicals that penetrate the hide, restoring moisture and aiding in the tanning process.
To rehydrate using tanning oil:
1. Evenly apply the oil to both sides of the hide, ensuring complete coverage.
2. Allow the oil to soak into the hide for several hours or overnight. This will restore moisture and flexibility to the skin.
If using a rehydration solution:
1. Follow the manufacturer’s instructions to mix the solution with water.
2. Immerse the hide in the solution and allow it to soak for the recommended amount of time, usually several hours or overnight. This will effectively rehydrate the hide and prepare it for the tanning process.
Applying Tanning Solution
After rehydration, the next step in tanning a hide for taxidermy is applying the chosen tanning solution. There are various tanning solutions available on the market, each with its own set of instructions and recommended techniques.
Carefully read the instructions provided with the tanning solution and follow them precisely. Mix the solution as directed and apply it to the hide. Use a brush or sponge to evenly spread the solution, ensuring that all areas receive adequate coverage.
Allow the tanning solution to penetrate the hide for the recommended amount of time. This can vary depending on the product and the thickness of the hide. During this process, the tanning solution chemically alters the proteins in the skin, turning it into a stable and preserved material.
After the specified time, rinse off any excess tanning solution and gently squeeze out any remaining moisture from the hide. This step helps remove any residue and prepares the hide for the drying process.
-
- Read the instructions provided with the tanning solution carefully.
- Mix and apply the tanning solution as directed.
- Use a brush or sponge to ensure even coverage.
- Allow the solution to penetrate the hide for the recommended time.
- Rinse off any excess solution and squeeze out moisture from the hide.
Stretching And Drying The Hide
Once the hide has been properly tanned and excess moisture has been removed, it is crucial to stretch it to its original shape and size. This step is important for achieving a smooth and professional finish.
Begin by carefully stretching the hide and securing it in place using t-pins or small nails. Place the pins or nails along the edges of the hide, making sure to smooth out any wrinkles or folds. The stretched hide should be left in a cool, dry, and well-ventilated area to dry completely. This process can take several days or even weeks, depending on the size and thickness of the hide.
While drying, it is essential to periodically check the pH level of the hide. Use pH strips or a digital pH meter to monitor the pH level, ensuring it remains within the recommended range. This helps prevent over or under-tanning, which can lead to issues with the finished product.
Once the hide is fully dry, carefully remove the pins or nails and inspect the hide for any imperfections or areas that may need touch-ups. At this point, the hide is ready for further finishing or can be mounted according to your taxidermy project.
Troubleshooting Common Problems
Tanning a hide for taxidermy can sometimes present challenges and unforeseen problems. Here are some common issues that may arise during the tanning process and the best ways to troubleshoot them:
-
Hair falling out: This can occur due to incorrect pH levels or insufficient fleshing. Maintain proper pH levels throughout the process and ensure thorough fleshing before tanning.
-
Smell: If the hide has a lingering odor, it may not have been properly neutralized. Soak the hide in a solution of sodium bicarbonate after the pickle to neutralize any remaining acids.
