Ok I'm heading to a chemistry shop tomorrow to see if they can help.... Actually I am thinking, and hoping they will make it for me, as its such a simple mix. Or at least I hope I don't need to buy 1 liter of sulfuric acid as that's gonna be a bit of a pain to deal with. If I get a small amount, Ill just take the small amount of formaldehyde and put it in, right? Obviously what ever container they sell me the acid in would also be ok for storing the marquis, and the formaldehyde while very toxic is not as dangerous or corrosive as the sulfuric acid so should be relatively easy and safe to handle.
The thing I really don't get... everywhere I research this tells me how DANGEROUS it is... but if the marquis you buy from dancesafe is actually the same mix or chemicals... isn't it just as dangerous to use for testing as it would be to make? I mean you still have to take these highly toxic and corrosive chemicals and put them to a plate etc. Why is it any more dangerous to mix them?
