Charles Goodyear figured out how to vulcanize rubber with the same stove that his wife used to bake the family's bread.
You should never use the same equipment for your chemistry as for your other household things. If you're going to do chemistry at home, do it safely. This means having a separate (well-ventilated) room for your work, and using separate ovens, microwave, glassware, and other equipment for your work. Chemical contamination is a real threat. You may look at a chemical reaction and deem all the reactants and products to be safe... but if you make a mistake you may contaminate a room/oven/glassware with a more dangerous side-product. And you do not want to be then ingesting these contaminants (worse, you do not want to expose your family and friends).
So, like I said, be safe and use dedicated equipment for your experiments. (And don't brush your teeth with the toothbrush you use to clean your test tubes.)
The only possible interpretation of any research whatever in the `social sciences' is: some do, some don't. -- Ernest Rutherford
