So I'm making an oil lamp-clock for my year project at school and I want to know which type of oil burns fastest. I can't find any info about the burning speed. I don't mean gasoline or any other fuel but oil like olive oil, sunflower oil etc.
The clock will look like this:
The oil is in that glass vessel and there's a wick on the middle part of the clock that connects with the oil and burns. The oil level gets lower and lower when the wick is burning. When the oil level reaches a digits (the ones on the side of the glass vessel) one after another you can see how much time has passed.
