âSpoons come in many different sizes and are not precise enough to measure a childâs medication,â said pediatrician Ian Paul, MD, FAAP, lead author of the policy statement. âFor infants and toddlers, a small error â especially if repeated for multiple doses â can quickly become toxic.â.
Copper and bronze do not contain any iron, and only iron can rust (because rust is defined as iron oxide, a compound of iron and oxygen); so the answer is that steel will rust the fastest and copper and bronze will never 'rust'. But, yes, copper and bronze do tarnish, they do corrode.
Solid gold or silver wire is your best bet, plated is the next best thing. Copper is good, but when it oxidizes it turns brownish, aluminum is good too, but when it oxidizes it has a powdery white oxide. Steel and iron are the worse as the oxide is red,,rust as we know it. Source(s):
