Self sealing pan gaskets

[gdmn852]

Thank you for your reply I wasn’t aware of the new material. As I mentioned in my post the cork did work well until it got soaked with oil then would sort of seep out ,like a sponge ,hopefully the new material is resistant to this . The tieing the gasket with strings must go back a long time it was one of the first things an “old timer”showed me years ago.
