Subject: [Homebrew_PCBs] My materials for "Cold Process?"

 

  

Hi, gang,

 

I'm going to pick up some glossy printer paper this afternoon (it's ONLY -10F today!), and I'm wondering whether my initial materials are a good fit for the process.

 

From Sally Beauty Supply I previously bought a quart of pure acetone. Should be good.

 

From the "real" pharmacy I have a couple bottles of "99% isopropyl" alcohol. Should be good, right? Or does it need to be "ethyl" or some other variety of alcohol?

 

I have four laser printers on hand, from old to new, so I should be able to find the "right" toner...

 

Thanks, as always,
