i was at the thrift this week and came across an induction hot plate for $6. Now i have been hearing all kinds of cool stuff about induction especially being able to control the heat better than your traditional stove top burner and for $6 how could you go wrong. I plugged it in before leaving the store and used a pot that was on the shelf as a tester and it worked. Now most of my pots are stainless and with reading it says it all depends with what kind of stainless if the burner will work of not with the pot, i read if a magnet sticks then the pot will work. Is this true? Any exception? Now why i find this induction control thing so fabulous is that i melt wax in a double boiler and it would be fabulous to make sure the wax does not get too hot with the temp control. The problem is that most of my double boilers are glass...aka VisionWare and clear Pyrex. I was reading there is some kind of metal plate you can buy to make the induction burner work if your pot is not induction friendly. Has anyone ever used one of these metal plates and does it interferes with the burner operation? And lastly can you use induction with a round bottom wok with a stand? The wok i use is stainless with a copper bottom and a metal stand that i have i have no idea what the metal is. Yes i am lazy and have not pulled the wok out and actually tried it(i am still trying to get the sticky price tag from the thrift off the burner). If it does not work, will it work with this metal plate that i mentioned in the previous paragraph? Thanks for the advice.
