Unlocking the Secrets of the Past: A Guide to Cleaning and Preserving Found Artifacts for Metal Detectorists
Cleaning and Preserving Found Artifacts: A Guide for Metal Detectorists
Metal detecting is an exciting hobby that not only provides a thrill of discovery but also offers a glimpse into the past. Unearthing artifacts such as coins, jewelry, or relics can be incredibly rewarding. However, once these treasures are found, they require proper cleaning and preservation to ensure their longevity and historical value. In this guide, we will explore the best practices for cleaning and preserving found artifacts.
1. Identification:
Before attempting to clean any artifact, it’s crucial to properly identify what you have found. Different materials require different cleaning methods to avoid damage. Consult reference books or online resources specific to your find or seek advice from experts in the field who can help you correctly determine its composition.
2. Documentation:
Never neglect documenting your finds before commencing with any cleaning process. Take clear photographs from various angles, noting any distinguishing features or inscriptions present on the artifact’s surface. This documentation will serve as valuable information for future research purposes.
3. Gentle Cleaning Methods:
Once you have identified your find and documented it thoroughly, it’s time to start cleaning with caution. The golden rule when handling ancient artifacts is to use gentle techniques that minimize the risk of causing irreversible damage.
a) Dry Brushing: Start by gently brushing off loose dirt using a soft-bristle brush like a toothbrush or artist paintbrush. Be extra careful around delicate engravings or fragile surfaces.
b) Water Bath: For non-ferrous metals like copper, bronze, or silver objects without intricate detailing, soaking them in distilled water might suffice for removing stubborn dirt buildup accumulated over time. Avoid using tap water due to potential mineral content that might react unfavorably with certain metal alloys.
4.Chemical Cleaners:
In some cases where simple brushing and water baths do not yield satisfactory results; mild chemical cleaners may be used cautiously under expert guidance.
a) Soap Solution: A few drops of mild dish soap or baby shampoo diluted in distilled water can be used to gently clean objects with non-reactive surfaces. Apply the solution using a soft brush, rinse thoroughly, and pat dry with a lint-free cloth.
b) Electrolysis: This method is suitable for iron artifacts suffering from heavy rust accumulation. Electrolysis involves creating a chemical reaction that removes rust without damaging the underlying metal surface. However, it should only be attempted by experienced individuals who are well-versed in this technique.
5.Preservation:
Once your artifact is cleaned and dried, it’s crucial to take steps to preserve its condition as much as possible.
a) Storage Containers: Invest in acid-free storage containers specifically designed for preserving metals and archaeological finds. These containers protect against exposure to moisture, dust, and air pollutants that could potentially damage your artifact over time.
b) Anti-Tarnish Strips: For metal objects prone to tarnishing like silver or copper coins, placing anti-tarnish strips inside the storage container can help prevent oxidation and maintain their appearance for longer periods.
c) Environmental Factors: Store your artifacts away from direct sunlight or extreme temperature fluctuations. Humidity levels should also be monitored since high humidity can accelerate corrosion processes. Consider adding desiccant packets to absorb excess moisture if required.
By following these guidelines for cleaning and preservation, you will ensure that your found artifacts retain their historical significance while remaining intact for years to come. Remember always; when in doubt about any cleaning or preservation method, consult experts or professionals who specialize in conserving cultural heritage materials.
