Unearthing History: Cleaning and Preserving Metal Detecting Finds
Cleaning and Preserving Metal Detecting Finds
Metal detecting can be an incredibly rewarding hobby, as each find holds a piece of history waiting to be discovered. Whether you are unearthing coins, jewelry, or relics from the past, it is essential to properly clean and preserve your finds to ensure their longevity and maintain their historical significance. In this article, we will explore some effective methods for cleaning and preserving metal detecting finds.
1. Initial Cleaning:
When you first retrieve an item from the ground, it is important not to rush into cleaning it immediately. Take a moment to examine the object’s condition and determine whether it requires professional assistance or if you can handle the cleaning process yourself.
For lightly soiled items such as coins or small artifacts made of non-ferrous materials like copper or bronze, start by gently rinsing them under running water using a soft bristle brush. Avoid using abrasive cleaners or scrubbing too vigorously as this may damage delicate surfaces.
2. Removing Dirt and Rust:
For heavily soiled items covered in dirt or rust, there are several techniques you can employ:
a) Electrolysis: This method involves creating an electrolytic bath that removes rust without damaging the artifact’s surface. It requires a container filled with water mixed with a suitable electrolyte (such as washing soda), along with sacrificial pieces of metal acting as electrodes. Submerge the find in this solution while making sure only its rusted areas come into contact with the sacrificial metal.
b) Mechanical Cleaning: For stubborn dirt or encrusted debris on metallic objects, consider using mechanical means like toothpicks, wooden picks, soft brushes (like toothbrushes), or dental tools designed for delicate work. Be cautious not to scratch or damage fragile surfaces during this process.
3. Stabilizing Fragile Finds:
Some metal detecting finds may require stabilization due to corrosion damage or fragility caused by extended exposure underground.
If you encounter an item that is crumbling or appears unstable, consult a professional conservator who specializes in archaeological artifacts. They can provide advice on how to stabilize the find and prevent further deterioration.
4. Long-term Preservation:
Once your metal detecting finds are cleaned and stabilized, it is vital to store them properly to maintain their condition over time.
Avoid storing metallic objects in humid environments as this can accelerate corrosion. Instead, opt for a dry storage area with controlled temperature and humidity levels. Acid-free archival boxes or trays lined with acid-free tissue paper are ideal for organizing and preserving small items.
5. Documenting Your Finds:
Lastly, don’t forget to document your metal detecting finds! Take clear photographs from multiple angles and record relevant information such as the date of discovery, location found, depth at which it was unearthed, and any other details that may be significant.
Creating a digital or physical catalog of your finds will not only help you remember each discovery but also contribute valuable data for historical research purposes.
Metal detecting offers endless possibilities for uncovering hidden treasures from the past. By following these cleaning and preservation techniques, you can ensure that each find retains its historical value while being enjoyed by generations to come. Remember always to prioritize proper care when handling delicate artifacts discovered during your hunts. Happy hunting!
