Charters Read Replies (2) | Respond to of 116845 We know that nickel, unlike copper, is a poison, and it seems from this study on nickel exposure that certain people are sensitive in tyhat they develop allergies to the metal. The Nickel Institute and Inco of course, would argue with them. Whether or not nickel were poisonous, it could still be prone to causing allergies in even miniscule amounts, if it were true that it had that activity, and it would appear that it may. The question this information may raise, if it is found to be significant, is to what extent may nickel in cookware have the same effect? Here nickel is alloyed with iron, and chrome as well as copper. Offhand I would say because of the alloying with other elements particularly chrome, the effect would be mitigated largely. We don't often hear of complaints of ill effects from stainless steel pots and pans, and the stuff does not seem to breakdown or release metals. If chrome or some other non corrosive element is known to reduce this allergenic effect, (titanium, and gold are known to be hypoallergenic -I don't know about chrome per se.) then it would seem prudent to alloy nickel with these elements where handling or other human exposure of the materials is a major factor. Maybe the future of cookware and other high exposure implements lies in titanium, or gold coated materials! We know that chrome may be reactive by itself. Platinum has an effect after repeated exposures to many people. Aluminum is hazardous and one must limit exposure. Copper is relatively benign, titanium is benign and iron is benign. If you want cheap, then iron is the answer. Why people use aluminum cookware is beyond me. Gold does not react at all in the human body. If coin were coated with gold, or knifes pots and pans, they would be very safe! How expensive would this be? In fact the monetary amount of gold to coat material electrolytically is merely pennies per square metre. 18 karat coatings would be more expensive, but the gold itself is not the expense. The real question, if it were ubiquitous is not the true cost, but the lastingness. But it has to last better than plastic and decidedly less poisonous. And I will bet the food does not stick. EC<:-}
