What’s a blue flame gas lighter?

The flame produced by the lighter and torch is blue, not red color. (such as the flame color of “zhentanzhe” manufactured GF9262 torch lighter as below).

They are used by many professionals such as chef’s, outdoor enthusiasts, mechanics, jewelers, laboratory technicians, and of course consumers. All burners are enhanced with a modern piezo ignition which ignites standard butane gas without any problems.
