Re: microwave ovens

Always good to "see" you on histonet.
May I draw on your unparalled knowledge re. microwaves, please?
Our microbiologists from time to time microwave small (50 - 100
ml) amounts of culture media in conical flasks with non-absorbent
cotton wool in the necks.
Recently, there was a smell of burning from the oven and when
taken out, the cotton wool was "burnt" and smelled like it. There
had been no flames (sorry about the English of that sentence!)
I believe I am right in saying that cotton contains oil.
May that have been the cause and how come, after the many
hundreds of times we have done it, the wool burned that time?
