väävliväätt

väävliväätt is a Finnish term that translates to "sulfur match" in English. It refers to a type of matchstick that has been treated with sulfur on its tip. This treatment serves to enhance the ignitability of the match. When the match head is struck, the sulfur ignites easily and helps to transfer the flame to the main combustible material of the match head, facilitating a more reliable and often brighter initial flame.

Historically, sulfur matches were a common type of friction match. The sulfur coating allowed for a quicker and more consistent ignition compared to some earlier match designs. While modern safety matches, which require a specific striking surface, have largely replaced older types in many parts of the world, the principle of using an easily ignitable chemical like sulfur to aid combustion remains relevant in various pyrotechnic and ignition applications. The term itself is a direct descriptor of its components and function.
