I’ve never canned but thought about doing so recently. Then I discovered you should never use a pressue canner on a ceran top range which is what I own.
If you have a ceran top range, I strongly suggest you contact the manufacturer before attempting to use a pressure cooker/canner. The glass top sits over electric elements that can electrocute someone if the glass top breaks.
Your comment has no technical standing whatsoever. Just what do you think happens every time you stir a pot with a metal spoon?
Our county extension resource person has canned for years using a ceramic stove top- a friend that started canning two yeas ago also.
