What is a vitreous ceramic cooker?
Ive had a ceramic hob for years I like it a lot. It heats up quicker than other electric rings but not as quick as gas ones. Its VERY easily cleaned. The only downside is that pans have to be flat so they have good contact with the ring. It's no good having cheap pans which bevel easily. They just take longer to cook, waste energy. The hobs are toughened glass so I suppose thats what vitreous means.
