I'm trying to make ferrofluid according to this guide: http://www.sci-spot.com/Chemistry/liqimag.htm and in step 5 I need to heat the solution to near boiling but I don't have access to a bunsen burner or heating plate. Also I can't do this in the kitchen because this heating is to remove ammonia gas. My question is can I heat a liquid to 100-110 degrees Celcius by wrapping a nichrome/constantan wire around a beaker and sending a current through it? Is there a better way to boil this liquid? Thanks.
