How much would it cost to perform a burn test of some heavy cardboard? I need to determine the degree of scorching it will suffer if I use it to laser cut a design. Thanks Ernie Hi.

We'll use this flame test here at TechShop to be sure no one kills us all in a cloud of Chlorine gas with one of our 2 laser cutters! THANKS! Lynne. GREAT info on keeping us from being dead!

The air I breathe sometimes is bad enough, I certainly don't need chlorine too. thanks for putting this up, as a pipefitter/welder, I’m all the time put in positions where things around me get burned up, now I can at least test some of them to know what I should absolutely have removed before I get at what I’m working on directly.

If you get a headache while burning "safe non-PVC's", it could be because of the CO. also remember that a propane torch releases CO (ie: carbon monoxide) which is poisonous.

Fluorine is so electronegative I doubt our puny laser can pry it from whatever it's currently bound to. PTFE appears to be reasonably safe.
