Enamelware is metal-not ceramic, so don't put it in the microwave!-made from steel fused with melted glass and fired at exceptionally high temperatures to achieve its signature glossy-hard finish. This process makes it easy to clean, rust-averse, safe to use in the oven, dishwasher, or freezer, and long lasting. There's a reason your grandmother still has hers. Like many centuries-old techniques, the hand-dipped coating + hand-painted details can present subtle variations in each piece. We think they're charming, and, never fear, these "imperfections" won't affect use.
Take Care: While it can withstand extreme temperatures and a host of other abuses (looking at you: camping with children) enamel's kryptonite is its vitreous coating. Don't bang it with a spoon or drop it like it's hot (even if it's hot!) or it can chip.
