SIMAXGlass Roaster Baking Dish, Large 5 Quart Rectangular Roaster Pan For Baking And Cooking, Oven and Dishwasher Safe Cookware, Casserole Pan

This might not look much different than any other glass baking dish but looks are deceiving! Glass bakeware is tricky because glass isn't really thermally conductive (meaning it doesn't distribute heat well), it expands and contracts when heated and cooled, and it's very brittle. What does that mean in practically? If you take a hot glass pan out of the oven and put it on a cool surface the bottom glass surface cools faster than the opposite inner surface, since glass doesn't distribute heat well you get a significant difference in temperature between the top and bottom of the glass pan, the bottom surface starts to cool and contract while the opposite inner surface does not. Since glass is brittle it cannot bend or flex to accommodate differences in thermal expansion and so it just shatters. The opposite is also true if you put a cool pan in an oven. So how do you fix this? You use glass that has a low rate of thermal expansion (meaning it expands and contracts less as it's heated and cooled). Most if not all glass bakeware used to be made from borosilicate glass. Borosilicate glass has a low rate of thermal expansion making it the ideal material for this purpose. You may have heard of the "exploding pyrex" controversy where pyrex users were suddenly having problems with their bakeware exploding. Ultimately it was discovered that pyrex had changed from using borosilicate glass to using the cheaper soda lime glass in their bakeware which has a higher rate of thermal expansion making it more prone to shatter from thermal shock. Funny, at the time at least this was only true for US pyrex products. European pyrex products were still made from borosilicate glass. Thanks a lot Pyrex! This Simax product on the other hand is made right, they way glass bakeware is supposed to be made, from borosilicate glass. I've had several occasions where this pan has survived incidents that would have caused the cheaper soda lime dishes to explode. I opened my oven door to load the oven. Unfortunately I had some difficulty and took too long letting the heat escape the oven. Well when I finally did close the door the oven heating element was on full blast glowing red hot only 2 inches away from this cool pan for several minutes to heat the oven back up. A modern pyrex dish could never survive that, not a chance. Now imagine that's the lasagna you spent all day making or your thanksgiving turkey you need ready in and hour and now it's splattered all over your oven full of glass shards ruined because you cheaped out buying an inferior soda lime glass pan. Mind you, not only is your dinner ruined but it's a fire hazard as well. Imagine hot grease and water being dumped inside your oven after your cheap pan explodes. The water oil mix instantly vaporizes when it hits the hot element and starts burning. Please don't do this to yourself. Save yourself the heartach and frustration and just buy a borosilicate glass pan. I know it's a few dollars more but the cheap soda lime glass pans other companies are trying to pawn off on you aren't worth it!!!

Size was great

So far it's good and only had it for a month and used it 2 times since then. Cooked my dinner great and the part I like the most is that it is easy to clean.

They stack! And the edges are rounded so less likely to chip. A size up from standard 9x13” which I sought out for larger batches … just the ticket.

I bought this specifically because Glass cooks so much evener (if that is a word)nothing burns and it cools fast when you take it out of the oven...it serves well in the see thru glass.coat it with butter, sprinkle Parmesan cheese (the powder kind) and coat like a cake pan. then put in the spagetti (i like the thin potsize noodles), then cover with the spaghetti sauce with ground hamburger in it. then sprinkle on grated Parmesan cheese - bake at 400 degrees for 45 min.....the crispy bottom and yumminess will have you making this weekly!

Had to take away a star because the cardboard product info was glued to the dish. After scraping away as much as I could with a knife and putting it through the dishwasher, I needed to scrub with acetone for ~10 mins to get all the glue off.

It holds what in cooking. It's large capacity love it..

So far it’s held up very well to my experiments better then most lab glass I’ve worked with it’s very stable at a wide array of different temperatures and i feel like it is well made worth the money for the thermal shock resistance
