- Take a deflagrating spoon. This is a little brass ladle, attached to the end of an iron wire. It is very commonly used for burning things in gases, for which purpose it is best to push the wire through a flat bung, protected on the lower side by a piece of tin-plate, which may prevent the gas from passing out of the bottle.
