If you can puzzle out German, you might find this article worth reading.  It describes SMD reflow in a toaster oven, and some of the pitfalls.  The main one is that the temperature sensor needs to be attached to the board, or to a (blank) copy of that board.  If it's attached to something with a significantly different copper to etch ratio, it will be heated differently and your board will either not heat enough, or be overheated -- possibly enough to scorch it.
