if your storage jar is pyrex.... put it on a gas flame and run for your life!  :lol:


Running for your life would be a good idea as a flame will smash pyrex... oven heat is OK, I found this out cooking when much younger :?

and did you know...??

The 'magic' ingredient for Pyrex is called Borax, and it nearly all comes from the one town of Borax in Southern California !

(I wonder how big THAT hole is by now???)

(at least according to my memory of some recent reading on the web, but I think it's correct!)

and I feel bound to point out...

The same sort of white effect can also be done to lead crystal or other sorts of glass, and is usually referred to as 'milk glass'. so please don't anyone think that ALL white glass is Pyrex or therfore ovenproof!

So, to clarify:

If your glass explodes in the oven, it's milk glass, and if it explodes over a naked flame, it's Pyrex.   :wink:  :P

There are glasses now that can cope with the direct flame... joys of modern technology. Only problem is I don't know what the glass is called.

Despite the flame resistance they still break when you drop them on a concrete floor :evil: one day someone will rediscover flexible glass and we can have flames resistant glass balls. Perfect for hell - our kitchen.

Yes it is glass, we have some in our pantry, we use them for rice and paste.

Here in NZ it was a Nescafe promotion, they were filled with coffee. 1970s is when we got ours.

:D:shock::D

Just the sight of the jar conjures up the image of it, half-full of nasty powdered instant "coffee", just starting to "cake".  :twisted:  I can SMELL it. Yeeeeugh!
I'm off to get a decent mug of real, Fair-Trade coffee. I need it to take that vile smell away!

Are they really that old......?
