In Milan-Cortina, organizers identified a solution within days. They will now offer repairs to all athletes, strengthening the faulty clasp connections to withstand the inevitable jumping for joy.
Many historical and modern medals are made of brass or bronze alloys with a high zinc content. These specific compositions are notoriously susceptible to season cracking, a form of SCC. Ammonia in the atmosphere, often originating from cleaning products, sweat, or even atmospheric humidity, selectively corrodes the zinc out of the alloy. This leaves behind a brittle, hollowed-out matrix that fractures under the slightest pressure. The Infamous "Bite Medal Crack"
Medal production involves high-pressure machinery. Medal cracks are essentially a symptom of a . Initial Strike: A new die strikes a medal flawlessly. medal crack
Once the structural crack is filled and stabilized, the surface must be protected. Conservators will carefully re-plate the damaged area to match the original gold or silver finish. Finally, they apply a microcrystalline wax or a specialized archival lacquer. This transparent layer seals out air and moisture, ensuring the medal remains intact for generations to come.
A collector’s worst nightmare is discovering a fracture in a prized piece of history. Whether it is a rare military decoration, an antique commemorative medallion, or a modern sports award, structural failure destroys both aesthetic beauty and financial value. In the numismatic and exonumia communities, this phenomenon is known as a . The Infamous "Bite Medal Crack" Medal production involves
Metals seem indestructible, but they are highly susceptible to environmental, chemical, and mechanical stress. The degradation of a medal usually stems from one of four primary sources. 1. Metallurgical Flaws and Die Stress Many cracks originate during the manufacturing process.
Do you need help for smoother recording? Refrain from biting
Refrain from biting, bending, or stress-testing the medal.
For brittle materials like ancient bronze or lead, jewellers may apply a hidden stabilizer. They mill a tiny channel across the back of the crack and insert a high-tensile wire made of inert metal, like titanium. This wire acts as an internal splint, absorbing physical tension and preventing the crack from widening. Re-Plating and Sealing
