# NC Fines - JB's IPA method
#### Using exactly 91% IPA is important
MW: JB accidentally stubbled upon this method to make "NC Fines". I'm going to add it to 'Aardvark'
JB:
I posted this pic a week or two again, about how I mistakenly added 91% IPA to NC lacquer attempting to thin it. I thought it was 99%>. This small amount of water caused the NC to precip as tiny particles
I filtered that out, took the filter paper with the precipitated NC, which looked like a gel more or less, and let it evaporate very slowly with a petri dish placed over 99% of the open dish, letting the alcohol phase evaporate off first. Then when the NC particles were only water wet, I put the dish into a dessicator

This is the result. It looks exactly like the NC fines that I have prepped manually (and laboriously) by hand grinding. I took this and ground it down a bit more and took it through a fine screen.
