Baking or cooking in glass, silicone, plastic, or pottery?
I've heard ALL sorts of stories over the many years I've been baking and working in bakeries and kitchens. Use metal or nothing at all.
Metal is fine, but there is nothing wrong with glass. Look at Pyrex. Pyrex has been making glassware since around the 1960's. I've never heard of anyone getting sick or dying from using glass to bake in or cook in.
Silicone. This stuff gives me the "willies". I would personally never use this. Silicone for bakeware has not been in use long, so there is no factual study that has deemed this artificial chemical a safe product to use. Although I have not heard of anyone getting sick from using said silicone, I cannot see where it is good. Then again, if there is something wrong with it, it may take many, many years before the effects are found out.
Cooking in plastic. Well, this is just simple logic. Plastic was adapted to the food industry for PRESERVATION of foods, not for cooking them. I've seen "news" stories where cooking food in plastic (microwaving food in plastic) leaks out chemicals in the plastic. This is true for anything you cook or bake in, plastic is just the most toxic at this point.
You would have to cook your food in plastic to the extent the plastic melts into the food item you consume, for it to have any relevant effects on you. Or, as previously stated, you would have to cook ALL of your foods, ALL day, EVERY day, for many, many years for you to have any noticeable effects.
But as I stated, plastic was designed for food preservation, not for cooking or baking.
I would think this concept is basic enough for a 5 year old to understand.
Pottery. Well, supposedly mankind has been cooking and baking in pottery for an eon.
So whats the big deal then? Apparently there are two different aspects of this.
One is that chemicals are used in the actual pottery while being produced.
The other one is that food particles get stuck in the porous clay and create harmful bacteria that could infect the next food item being baked or cooked in it.
First off, most cooking pottery has some sort of glaze or finish on it to fill in those porous parts of the clay. Secondly, unglazed clays can be scrubbed clean. And even if some food particles are missed, any bacteria is usually killed during the next baking or cooking session.
As far as chemicals being used in the clay itself, I'm sure thats true to some extent. These chemicals are usually bonding agents to strengthen the clay and create a longer lasting piece of cookware. The chemicals are the same types found in glass, teflon coated, and enamel coated cook and bakeware. So it's not like they are dumping toxic waste into the clay before they press it and fire it.
If mankind lasted for millennia without the benefits of soapy water, bleach, and filtered water to clean their pottery with............I'm sure we will last another millennia.
