Here's a simple tip. Use a steel spoon to stir the wort. If you do not, you are overlooking the effect of heat transfer. You know when you stir hot coffee or tea, the spoon comes out hot? Take advantage of that. Stir, set the spoon aside to cool. Repeat.
edit: of course if you transfer to a plastic fermenter, switch to your sanitized plastic spoon at that point so as not to scratch the fermenter.
