Cast Iron Q&A: Put A Lid On It

(No, this has nothing to do with political arguments.) Join us on Cast Iron Wednesday for a live chat, and cast iron Q&A session. The general subject this week is: LIDS. We take the lids on our pots and pans for granted, and there are quite a few things to talk about when it comes to lids on cast iron pans. Everyone is encouraged to ask questions and answer questions! Topics we can discuss include...
- Older gate-marked lids
- Which lid will fit this old skillet or pot?
- Why did Wagner and other companies stop making lids?
- What are those spikes on the underside of this lid?
- How do I clean this &%#*#! lid with those spikes underneath?
- Details about lids from older cast iron manufacturers, including identifying unmarked lids
