How to identify your metal detecting finds

When embarking on the journey of identifying your metal detecting finds, it’s foundational to distinguish between different types of metals and alloys, as this will greatly aid in artifact identification. Metals commonly unearthed include iron, copper, silver, gold, and lead, each possessing distinct properties and appearances. Iron objects are usually found in deteriorated condition due to rust and may require further verification through tools. Copper tends to tarnish, turning green or brown, which is often seen in old coins and artifacts. Silver items, which can be tarnished black, are typically heavier and bear more intricate designs. Gold rarely tarnishes and maintains its distinctive yellow sheen, making it relatively easier to identify. Lead, on the other hand, is soft and heavy, often found in the form of small bags or as part of statues.

Alloys, which are combinations of two or more metals, can also be frequently found. The most familiar alloy for metal detecting enthusiasts is bronze—an amalgamation of copper and tin—known for its historical use in tools and coins. Brass, another common alloy made from copper and zinc, often surfaces as old ornaments or fixtures. Understanding the specific qualities of these metals and alloys not only enhances identification accuracy but also increases the understanding of the historical and cultural context of the finds.

Recognizing these materials involves a keen observation of color, weight, and surface characteristics. For instance, comparing the heft of an object in your hand against the known weights of metals helps determine if a coin is made from genuine silver or a lesser-value metal. Each metal reacts differently to exposure and time, which is pivotal in artifact identification and helps to differentiate between items with similar appearances.

Further identification can be supported by the use of simple tools such as a magnifying glass or jeweler’s loupe to discern small markings or inscriptions, which sometimes hold the key to fully identifying the type of metal or alloy and potentially the origin and age of the coins or other artifacts discovered.

Using a magnifying glass and other tools

Using a magnifying glass is among the primary tools necessary for the close examination of metal detecting finds. It allows for a detailed inspection of any etchings, hallmarks, or fine details that are otherwise invisible to the naked eye. These miniature clues can be critical for accurate artifact identification, especially when dealing with small items like coins, where mint marks and year of production are key to determining their value and origin.

In addition to a magnifying glass, a metal detectorist might make use of various other tools to enhance the accuracy of their findings. For example, a jeweler’s loupe, offering higher magnification, can provide an even closer look at intricate patterns or inscriptions on jewelry or metal artifacts. Pinpoint probes can assist in locating tricky, small items embedded in the soil, while metal testing kits help confirm the composition of the metals found, distinguishing between look-alike materials such as gold and pyrite.

With technological advances, portable metal analyzers have also become an invaluable tool for those keen on exact material identification. These devices, though costly, rapidly provide the elemental composition of the metal in question, altogether stepping up the process of identifying complex alloys or verifying the presence of precious metals in ancient coins.

For those working on more generous budgets, harnessing the capability of an XRF (X-ray fluorescence) analyzer can offer non-destructive testing of metals, which is a gigantic leap forward in preserving the integrity of historical artifacts while still determining their composition. This is particularly useful in environments like museums or historical sites where invasive testing methods cannot be employed.

Each tool plays a critical role in piecing together the historical and cultural puzzle left behind by past civilizations. Whether it’s deducing the age of a simple copper coin or confirming the presence of rare elements in what appears to be a mundane piece of metal, these tools aid immensely in transforming a seemingly trivial find into a significant historical artifact.

Dating and contextualizing your finds

Dating and contextualizing your metal detecting finds is an intriguing task that involves piecing together both the chronological age and the historical context of the discovered items. By effectively analyzing the age and relevant background of your finds, you can greatly enhance your understanding of the significance of each artifact, particularly when dealing with coins, tools, and decorative items that reflect the cultural or technological epoch to which they belong.

Understanding the era in which an item was used begins often with visual inspection. For instance, coins can usually offer definitive clues through the year they were minted, which is typically printed on them. Further inspection might reveal specific stylistic features or iconography that aligns with certain historical periods. For artifacts that lack visible inscriptions or discernible date marks, one might consider context clues from the location of the find itself. Items found near known historical sites can be tentatively dated to similar periods unless evidence suggests otherwise.

Research plays a pivotal role in the dating process. Accessing historical records, old maps, or archeological databases can provide information that links your finds to specific time frames and events. Knowledge of local history is particularly useful as it allows for a contextual understanding of why certain items may be present at a particular site. This research helps to build a narrative around the artifact, which can be critical for both academic purposes and personal satisfaction.

In the case of metal objects whose origins are less evident, technological methods may be employed. Techniques such as metallography can analyze the microstructure of metal and may provide insights into manufacturing techniques and periods. Similarly, radiocarbon dating and dendrochronology can be used for organic materials associated with metal artifacts, such as wood handles or organic residues, providing indirect dating of the metal components.

Each piece’s place within its historical context not only enriches the story of the find but also contributes valuable information to the broader narrative of global and local history. By compiling and comparing the data from various sources, enthusiasts can often pinpoint an artifact’s origin and era, lending invaluable insight into past civilizations and societal structures.

Thus, the careful dating and contextualization of your metal detecting finds transforms simple recovery into an exciting exploration of history and culture, allowing a deeper connection between the past and the present while enhancing the overall experience of artifact identification.

Cleaning and preserving discovered items

Cleaning and preserving discovered items from metal detecting endeavors is paramount to maintaining their integrity and appearance over time. Improper handling and cleaning methods can cause irreversible damage, stripping away historical value and the potential insights they may carry. To effectively preserve these artifacts, a series of gentle but meticulous steps should be followed.

Firstly, it is crucial to assess the material and condition of the find before attempting any cleaning process. Abrasive cleaning methods can harm softer metals like gold or certain types of alloys, while water can be detrimental to objects like iron which are prone to rust. Therefore, identifying the nature of the metal, as discussed in earlier sections of this guide on artifact identification, is fundamental.

For non-ferrous metals such as copper, bronze, and silver, which are typically found in coins and jewelry, gently cleaning with distilled water and a soft toothbrush can remove superficial dirt without damaging the patina, which is often desirable and adds value to antique pieces. For more tenacious grime, a diluted solution of mild soap can be used along with minimal agitation. It is essential to completely dry these items after cleaning to prevent any water-induced corrosion, especially in the case of copper-based alloys which can tarnish easily.

Iron artifacts necessitate a different approach due to their susceptibility to rust when exposed to moisture. Mechanical cleaning methods, such as using a soft brass brush, can be effective in removing rust flakes. For more advanced cases of corrosion, electrolysis can be considered. However, this technique should only be performed by, or under the advice of, professionals in artifact preservation to avoid damaging the structural integrity of the metal.

Once items are cleaned, preserving them involves controlling their environment to prevent future deterioration. Storage in conditions with stable temperature and humidity is ideal. Use of acid-free materials, silica gel packets, and sealed display cases can further protect delicate items from the elements. For metal detecting finds with significant historical importance, consulting a conservation expert for proper preservation techniques and storage solutions is highly recommended.

In addition to physical preservation, applying a protective coating can be beneficial for certain metals. Renaissance wax, a micro-crystalline wax polish, is widely used by museums and collectors to provide a barrier against pollutants and handling, which can both oxidize and wear away the surface of metals over time.

Ultimately, the cleaning and preservation of artifacts not only prolongs their lifespan but also enhances their aesthetic appeal, making them more enjoyable to display and valuable to collect. With appropriate care, your metal detecting finds will continue to reveal and retain their historical significance for future generations.

Recording and reporting your findings

Recording and reporting your findings are crucial steps in the process of artifact identification, particularly when your metal detecting finds include items of potential historical significance. Properly documenting and, if necessary, reporting your finds ensures that significant artifacts are recognized and preserved within the appropriate historical context, while also contributing to the broader archaeological and historical knowledge base.

When recording your finds, start by taking detailed notes of each item’s location, depth found, and surrounding context. This information can be crucial for professional archaeologists or historians attempting to piece together site-specific histories. Photographs are equally important; they should be taken from multiple angles to capture the complete appearance of the item before any cleaning or preservation work begins. For items like coins, capturing clear images of any inscriptions or designs is particularly vital as it aids in later research and identification.

Using a standardized form or database for recording details can help maintain an organized log of all discoveries. This should include columns for date found, item type, materials, dimensions, condition, and any initial findings regarding age or function. There are several software tools and mobile applications developed for hobbyists and professionals alike that can assist with detailed record-keeping. Such meticulous documentation not only enhances personal collection management but can also prove invaluable should the items need to be evaluated by a professional.

Regarding reporting, the laws and regulations concerning the discovery of potentially important artifacts vary widely by location. In many places, items that are suspected to be of significant historical value must be reported to local authorities—this can include anything from old coins to significant metal artifacts. In the United States, for instance, the discovery of any items on federal land that could be classified as ‘archaeological resources’ must be reported under the Archaeological Resources Protection Act. It’s your responsibility to familiarize yourself with these laws to ensure compliance and help protect historical legacies.

For those finds that are not legally obligated to be reported, it is still considered good practice to share significant discoveries with the archaeological community. Many professional archaeologists appreciate learning about new finds from hobbyists, as each new item could add a piece to the jigsaw puzzle of human history. Engagements can be as simple as participating in online forums dedicated to metal detecting and artifact identification or presenting notable finds at community meetings or exhibitions.

Taking these steps not only enhances your experience as a metal detectorist but also ensures that your metal detecting finds are properly recorded and conserved for future generations. The data collected from these activities provide significant insights into past civilizations, enriching our collective understanding of history.
