Good luck with your emulsions and keep us informed on your progress! We like to share information here.
If you are coming to town, and need chems, I likely have enough to get you started with a lot of stuff, although I am not in the mood to sell off the silver nitrate I have around. Other stuff will go for a fair price; not more than I paid, and if it was free to me it can be free to you.
Yes, Dave I am a fair bit of a mix from raw nut, but have not made my own stuff from nitric. That and hydrofloric I do not keep in the house, although I have a fair collection of stuff that if my wife ever cottoned onto she would flip.
I've got hydrofluoric acid. It stays in the garage.
Nitric, HCl, and Conc. Sulfuric are in the house though... All away from the Conc. Ammonium Hydroxide.
