My favorite type of cookware to use are the ones that are made of either glass or ceramic.
I feel that cooking with this type of material is safer than cooking with some of the other cookware materials such as aluminum. Materials used to make other types of cookware can react and even enter the foods that are cooked in them.
I also find that ceramic and glassware are easily cleaned compared to aluminum and steel. Some of the ceramic products such as the original Corning wear can go straight from the stovetop into the oven. In more modern times this has been even more useful by being able to go from microwave to the oven.
I love to use Pyrex bake ware as it is easy to see though the pan into the food that is cooking to get a good idea if it is cooking well or not.
I also enjoy the use of glass lids on the pots to check on the contents without lifting the lids and allowing the steam to escape. Pyrex glass ware is the only type of cookware I use for microwaving as I don’t want any of the plastic from other products leaking into the food.
Glass and ceramic materials also resist corrosion unlike some of their metal counterparts.
Teflon is easy to use because of it’s quality for non-sticking to food but you really have to wonder how much of the Teflon product is entering the food while it is being cooked. I have used the Visions line of glass pots and pans.
Even though they are completely made of glass, I have never broken one when dropped. I really like the different colors that they came in, amber was my favorite. The visibility to see the cooking process happening inside the pot is really a great. If you have never tried using ceramic or glass ware for cooking, I suggest you try it!
