| SHEDDING SOME LIGHT ON JEWELRY
& METALS: The E.U. Nickel Directive which was passed on the 30th of June, 1994, states that, " Nickel may not be used in post assemblies which are inserted into pierced ears and other parts of the human body during epithelization of the wound caused by a piercing. Whether subsequently removed or not, unless such post assemblies are homogeneous and the concentration of nickel, expressed as mass of nickel to total mass, is less than 0.05%." THE TRUTH ABOUT 9ct, 14ct, and 18ct GOLD: Did you know that 9 carat gold only contains 37.5% gold and the rest is made up of silver, copper, zinc, palladium, nickel and other elements, which, when combined with body acids, will cause it to tarnish easily? In Sweden, it is illegal to call 9ct "gold". Even higher carat golds are more likely to tarnish in genital and oral piercings than other piercings. If however, you wish to use gold in the initial piercing, a minimum of 14ct gold which contains 58% gold or 18ct (75% gold) is recommended. Higher ct golds (22 and 24) are not suitable as they are far too soft for the application. Warning: Gold also contains nickel which isn't very good and may cause infections and irritations. There is now a substitute for nickel in gold so it is possible to have 'nickel free' gold. It is a special process. Ask your supplier. GOLD PLATED JEWELRY: It doesn't matter how light the ct coating is. It is still going to wear off leaving small flakes of gold in the piercing. Another thing that concerns the piercer is the process for gold plating surgical steel of any grade. It goes through a process involving cyanide and mercury, neither of which are good for the body. So think carefully: IT IS NOT SAFE! THE TRUTH ABOUT SURGICAL STEEL AND IMPLANTATION STEEL: Otherwise known as the kind you are most likely to find in pharmacies. Iron based alloys have a medical based history extending over three hundred years. In 1667, Fabricius described the use of wire hoops for wound closure and in 1886, Hansmann reported the use of steel sheets for fracture fixation. In 1916, corrosion resistant stainless steel was developed (containing a minimum of 10.5% chromium. Stainless steels achieve their inert characteristics through the formation of an invisible and adherent chromium-rich oxide surface film) and this surgical implant material evolved. In 1947, the American College of surgeons recommended stainless steels for biomedical implant applications. Stainless steels are categorized into four general classes, based on composition. The higher grade series comes with very low percentages of carbon, nickel, and manganese. However even the best grades of stainless steel, which are nickel holding steels, are now outlawed throughout the EU for Primary Piercing Insertables. |
