The items you will:
Small tin container (altoids tin)
CardboardDisposable container for melting wax
Next pack the tin so the exposed side of the cardboard is facing outside of the tin. I use a spiraling shape but it makes no difference on how it’s formed to fit. It does, however matter how tight it is placed it the tin. If it is so tight that the cardboard’s zig zag pattern within its side walls is flattened then the wax won’t fill inside and the flame time will be shortened. Having the best ratio of wax and cardboard is the goal.
Next melt the wax and pore it slowly into the cracks of the cardboard ensuring that it has as little air as possible. The goal is to allow the cardboard to burn slowly. In short, you are creating a candle with a large surface area. The round one is what I am going to use to light a pumpkin!
