I have a 2 qt. glass pyrex bowl. On the bottom it says, "No Rangetop. No Broiler." Do you think I can bake a cake in it or not? If it's no broiler, would that be no oven at all do you think? I am clueless about this, but the bowl is the perfect shape for a cake I'm going to make on Sunday. Any opinions would be greatly appreciated. Thanks.
I don't know for sure, but my guess would be, no broiler because it is such a high temperature. I think alot of people bake in these. I personally haven't. What temperature are you going to bake at? Maybe you can go lower, say 300 or 325? I would just watch it very closely!
Good luck!
I can tell you what happens when you put in on a burner on the stove top.....I had set a pyrex pan on the front burner and turned it on by accident (meant to turn the back burner on). The pyrex heated, and then it started to smell like something burning. I quickly removed it with potholders and the pyrex exploded into 1000s of chards. Thankfully no one in my kitchen was hurt, including myself, but it did burn my linoleum floor (great excuse to replace it!). What a mess. Be careful in that regard! 
lower your temp by 25 degrees when baking in glass-it cooks faster on the outside. You can't put the glass on the broiler or rangetop because I believe Pyrex is only safe to 400 degrees and that direct heat may crack it.
I bake in mine all the time, along with my Pampered Chef batter bowl, my Pfaltzgraff dishes, etc. Never have a problem.
My glass pie plates and loaf pan also say no stove top or broiler. Inst. always say do not bake over 350 degrees. Since I've never used them for anything other than pies or meatloaf can't say if they cook faster or not, now I am curious to see what others say about that.
I use my Pyrex bowls and rectangles in the oven all the time. I did bake a cake in the bowl once too and it was just fine. 
I frequently have baked in glass and Pyrex with no problems; my min wedding cake was cooked in a few glass dishes. In addition from what others have said about no broiler and no range top dont put any cold liquids in them when they are hot. The rapid cooling could cause them to shatter as well.
The warning Pyrex gives is don't take a bowl from the refridgerator and put directly it into the oven & visa versa-the quick temp change can break the glass. Don't take Pyrex from the oven and shock it -same possibility of exploding. The rapid change in temp will make it explode, just as ump107 said about cooling off.
One more tip, although you probably wouldn't do this with cakes you might with other foods....
Lots of ovens use the broiler during the preheat period of heating so never put a pyrex pan into the oven until the preheat period is over unless you are SURE your oven doesn't use the broiler to preheat.
Word to the wise...it does say nor broiler use on the bottom.
Besides that all pyrex can be used in the oven...Ijust love the stuff!
