IS pyrex safe?

[Guest guest]

I found out that Pyrex uses aluminum in the glass to make it stronger.

Is it safe to store food in or cook in?

The pyrex I use to store food has plastic lids. I do not place them

on top until the food is cool. Is it ok to use plastic lids. I would

rather not use plastic at all. I just have not found an alternative.

****where did you get this info? i use pyrex and would like to read more

about this.

Most glass has some metals in it. For one thing, that's how they get the

color. Lead crystal has LOTS of

lead in it. But Pyrex is very, very stable: if it was leaching chemicals it

would foul up the experiments

of very many chemists doing sensitive tests. Pyrex is used to hold

extremely strong acids (the kind

that would eat up your standard pan). Strong bases (like the old oven

cleaner) CAN leach it, and

so can strong dishwashing soap, but you are unlikely to eat anything that

basic. Most eating

foods are on the acid side, and stable with glass.

****what about *clear* glass like the pyrex bowls with plastic cover that i

and others use? does the clear glass also contain some metals? are there any

bowls/storage containers that don't contain any metals to your knowledge?

does stainless steel leech metal as well?

*******what do you think about raw ACV? i've often soaked my dogs' meat in

ACV in these pyrex bowls. i also marinate my steaks in them using balsamic

or other vinegar.

Really, glass is the safest thing anyone has come up with. That's why they

use it in chemistry so much.

The chemistry experiments would get really fouled up if trace metals got

leached into the

solution -- really! And they are boiling nasty stuff in glass (pyrex)

beakers -- if leaching was

going to happen, it would, and they would notice it.

But the glassmakers all use some metals, I think, otherwise it would be

very brittle. It is in very

tiny amounts though, and it is very much bonded to the silicon. I kind of

think all glass has some

metals, including aluminum. So all your coffee cups, drinking glasses etc.

would be suspect.

(glazes on cups are FULL of metals). But there really isn't any reason to

think the metals leach

out except in certain cases (low-fired ceramic being a big culprit).

And most of your steel is a mix of all kinds of metals too. So stainless

could well have some aluminum

too. Stainless doesn't " leach " like pure aluminum does, but molecules here

and there do in all

probabilility detach.

I suppose you could go to wooden bowls -- they would get their own colonies

of bacteria maybe (there

is some controversy on that), but the chemicals that get leached would be

organic. If you used

oak you could get some nice flavor too. Unless the tree was grown in a

dioxin-contaminated area.

But trees concentrate some metals too, so you can't be gauranteed that the

wood doesn't have

aluminum in it.

Personally I would not worry about it much. The clay that is in Celtic salt

probably has some metals

in it too, and so does a lot of food. Your body can deal with a bit of

metallic stuff now and then. A lot

of the really toxic metals are required nutrients in small doses.

I'd worry more about the organic chemicals in plastics (don't heat plastic).

Glass only dissolves in base (alkali) solutions to the best of my

knowledge. Anyway, we used beakers

with really strong Hydrochloric Acid in them in chemistry class (and those

same beakers got used

for years and years) with no ill effects. If ACV = apple cider vinegar, no

problem. Anyway, ACV comes

in glass bottles, does in not?

I imagine the aluminum in Pyrex is tightly bound up in complex

alumino-silicates, and the raw material is, no doubt, alumina

(aluminum oxide) rather than reactive metallic aluminum. I seriously

doubt that any food would be able to leach aluminum from a refractory

glass like Pyrex. BTW, clay is a hydrated alumino-silicate; it's

metallic aluminum we need to avoid ingesting.

****price found healthy primitive peoples in various parts of the globe

consuming clay regularly. they dipped their food in a solution of clay and

water. some of the people explained it was to avoid 'sour stomach.' while in

africa, price suffered from dysentery, and was treated with clay. he reports

it was a very effective treatment.

-Hi Suze,

There was kaolin, as in Kaopectate, in the clay mixture the natives

dipped their food into before eating it. Kaolin in modern medicine is

a " protective agent for the gastric and intestinal mucosa and as a

rememdy for bacterial infections of the gut... " (Page 267 NAPD) What

smart people Dr. Price found in the most remote places!

It also serves to bind phytotoxins that are found in many plants such

as the glycoalkaloids in potatoes. This may have been the most

important reason for consuming it since most cultures that use edible

clays have a very high proportion of plant matter in their diets.

Clay consumption is extremely low in populations that consume a large

proportion of animal products.

Maybe the vegans would do better if they ate more dirt? Funny thing:

we have a vegan restaurant in Minneapolis that's called The Mudpie.

Mudpie is definitely not on the menu, but maybe it should be...?

I got this info out of the dictionary under pyrex.

Accidently ran across the word will hunting for another.
