...perhaps it's unworthy for starting a new thread, but we got sick and tired of buying stuff, and then ruining a pair of scissors cutting it to size...and in the end being also stung in the thumb..
...obviously this is not intended for the volcano vaporizer...
So this is what we do: finding 0.010mm or 0.020mm
uncoated pure copper wire, unwind about 3 x our body lenghth, and then slowly, slowly rolling it in a chaotic pattern into a ball...compressing it more and more. Finally it can be hammered into something round of the desired diameter....
edit: yes, flame it with a torch for some time prior to first use ! There is always some oil on it to stop oxidation and make it look shiny. Burn it off. Avoid any laquered copper wire !!!
