Hand-crafted in solid Sterling Silver, the Tesla collection incorporates elements of the inventor’s inventions thoughts and ideas. Nikola Tesla’s signature is prominently displayed in high relief on the pen barrel, along with a rotating magnetic field and the symbol for Alternating Current. The Tesla Coil is seen in the background, engraved in low relief. The gripping section is engraved with his AC Generator and Induction motor drawings. High relief electricity surrounds the Tesla Tower clip on the cap, and an X-Ray of Tesla’s hand can be seen in the low relief coil in the background. Atop the crown in high relief stands a Tesla unit of measure for magnetic induction or magnetic flux density, equivalent to one weber per meter squared, and resting against the breast is Tesla’s beloved white pigeon. Hard Enamel The Nikola Tesla Collection continues in the spirit of artistic mastery and the tradition of Old World craftsmanship by combining the centuries-old technique of Guilloché with the art and expertise of Hard Enamel. Using a mortar and pestle, a composition of glass, water and metal oxides is ground for hours by hand. When settled, the water is removed, leaving the fine paste that is the basis for hard enamel. A quill is then used to apply each coat of the mixture to the surface of the metal, ensuring that the entire guilloché area is completely covered in enamel. The components are then fired in a furnace at temperatures exceeding 1,000° F, fusing the enamel to the metal and forming a layer of glass. After cooling, the pieces are manually ground with a diamond file, restoring their proper shape and surface. This tedious process is repeated at length until the level of enamel reaches the depth required to cover the peaks and fill the valleys of each intricate guilloché pattern. When the final stages of firing are completed, the pieces are polished and buffed, revealing the velvet finish of translucent hard enamel. Available as a fountain pen or rollerball in Purple, Red or Orange Cap with Purple body.
