Reproduction of Wollaston's mouth blowpipe
The need to apply heat to very small amounts of material or areas resulted in the development of blow pipes. A fine jet of air is directed through a flame by blowing down the pipe resulting in a small part of the flame being blown out into a tiny sharp flame of higher heat intensity. Many types of blow pipes have been made, the variations being due to features such as water traps and swivelling orifices.
