Question:

Can you put a glass pan directly from the fridge into a preheated oven?


Answers:
as long as its Pyrex

They might crack. I would let them sit out for a little while first.

NO.. I think it will crack..

Not unless you want to watch it shatter! Let it reach room temp, or, transfer to another dish before you heat it.

I would'nt but you should try it and let us know.

yes, that glass is tempered to do just that

Manufacturing process
Borosilicate glass is created by adding boron to the traditional glassmaker's "frit" of silicate sand, soda, and ground lime. Since Borosilicate glass melts at a higher temperature than ordinary silicate glass, some new techniques were required to bring Pyrex into industrial production. Borrowing from the welding trade, new burners combining oxygen with natural gas were required.


[edit] Composition and physical characteristics
Borosilicate glass has a very low thermal expansion coefficient, about one-third that of ordinary glass. This reduces material stresses caused by temperature gradients, thus making it more resistant to breaking. This makes it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. It is also used in the processing of high-level nuclear waste, where the waste is immobilised in the glass through a process known as vitrification (contrast with Synroc).

Borosilicate glass begins to soften around 821 °C (1510 °F); at this temperature, the viscosity of type 7740 Pyrex is 107.6 poise. [1]

Borosilicate glass is less dense than ordinary glass.

While more resistant to thermal shock than other types of glass, borosilicate glass can still crack or shatter when subject to rapid or uneven temperature variations. When broken, borosilicate glass tends to crack into large pieces rather than shattering (it will snap rather than splinter).

As long as it is oven safe, yes.

But to be on the safe side I normally set them out of the fridge when I turn the oven on to pre-heat.

ONLY if it is "PYREX" or another equally quality brand. Usually you can find cautions or whatever written on the bottom of the pan, but if you cannot find any, it would be BEST NOT TO DO IT!!! Just to be on the safe side & to keep from having a BIG clean up job...PYREX is high quality & I have never had one fail...I have been married for 14 years & I still have an 8 x8 & a 9 X 13 Pyrex baking dishes that I had before I got married. I also still have my Pyrex measuring cups....
