I was getting something to burn and smoke up this empty 2 liter bottle for my friend's brother's science experiment. We didn't find any wood, so I took his trumpet valve oil, dripped some on a piece of wood that wouldn't burn and make it smoke up. Does burning valve oil have any negative side effects as opposed to say, regular oil? I shouldn't have been so lazy and just used vegetable oil or something haha....
Valve oil is basically just mineral oil and various other ingredients. You can buy pure oil, and it's also the main ingredient in baby oil and other medicines. Nothing wrong with burning it.
