Glazen deksel

Steam beads up on the glass so evenly that I can watch the sauce reduce without lifting the lid and losing heat. It's heavier than I expected, which makes it sit snugly on the pan rim, and clean-up is just a quick rinse.

Finally a lid that actually fits flush on my carbon steel pan — the tempered glass is thick and reassuring, and I can finally watch my sauce reduce without lifting it every two minutes. The steam trapped against the glass keeps my veggies from drying out on low heat. Exactly what I needed.
