I cover the whole bath/heating issue in my article here: http://w ww.ilpi.com/inorganic/glassware/heatsources.html

< div>At the very least, get these guys to convert to silicone oil, which has a higher flash point.

 Dear members,
Happy New Year! I have a few questions for the group on the use of mineral oil bath for organic syntheses. Our researchers swear by them. However, if left unattended on a hot plate, it can cause a fire if the oil overheats. This has happened a few times on our campus.
My questions for the group are as followed:
1.    .What temperature range is normally accepted for oil versus some other medium.
2.     Ho w long do you use an oil bath before you change the oil, or better yet what factors would dictate that you change the oil.
3.    What safety margin do you set for the rheostat, if the flash point is x do you set the rheostat to x-?.

Any thoughts or suggestions on this subject would be most welcome. Again, thank you very much for your help.
Best wishes
