When it comes to glassware, Pyrex is probably as unbreakable as it comes. Developed 100 years ago, Pyrex is made of nonporous glass that won't break, warp, or stain in situations where lesser containers would fail. The product is oven-, microwave-, fridge-, freezer-, and dishwasher-safe and comes with a 2-year warranty, but its devotees know that it can last much longer than that. Available on Amazon; $27.22 for 18-piece set.
