Who would have thought that an old enamel mug costing a few dollars and an enamel pot costing thousands of dollars are made using the same process! I used to think that chipped enamel would cause heavy metal poisoning, but that's a myth. High-temperature sintered enamel is very stable; chipped enamel will only rust and is not toxic at all. Why have such durable and safe items disappeared? They were expensive to manufacture, easily damaged, looked outdated, and there were fewer and fewer factories producing them, so they gradually faded from our lives. They weren't eliminated at all; they just changed to a more high-end identity and continue to play a role in water heaters, ovens, and chemical plants! Who would have thought that cheap old enamel mugs and thousands-of-dollars enamel cookware use the exact same process! People used to think chipped enamel causes heavy metal poisoning, but it's all rumors. High-temperature sintered enamel is very stable; chipping only causes rust and is not toxic at all. Why did such durable and safe things disappear? High production cost, easy chipping, outdated designs and fewer factories made it fade from daily life. It was never eliminated — it just got a high-end identity, hidden in water heaters, ovens and chemical plants continuing to work!
