Be careful when heating in the microwave, though, as it will get very hot very fast, and I have seen those bottles start to get soft. One would assume that with enough time, the bottle would actually melt.
This is why submerging in boiling water is my method of choice! It is much more controlled.
Yes the bottle will melt, plus the epoxy is going to outgas in the microwave, lots of esters in epoxy that are not good for you.
I don't even use boiling water, what ever temp it comes out of the tap will get the job done just fine.
