I'm very excited about NURDRAGE's recent success with producing Na. If you don't know about it, here's a link: In the video he uses hypoallergenic baby oil so nothing really reacts with it. Since a large quantity would cost so much, I was wondering if It would be possible to substitute it for paraffin oil or even some sort of motor oil? I've been wanting to also make an oil bath apparatus so a general purpose oil (aka oil for high temp) for both applications would be nice. Any ideas on what I could use apart from buying hypoallergenic baby oil?

I'm trying to make nitric acid. The "classic" nitrate salt+HCl+Cu process. A friend gave me the nitrate in fertilizer form and neither of us even had a clue if it contained nitrates, however I tried making a small batch to see if it works. It didn't generate any visible NO2 gas. At least there didn't seem to be any orange/red-ish fumes in and around the bottle. Hoooowever gas was being generated (colourless) and the Cu was being eaten up. After some time the solution started turning dark green. A while after that, clumps of a percipitant started forming in the solution. Seemed to be white, but slightly green because of the color of the solution. I took the clumps out since they started blocking the gas from leaving the bottle and checked if they could be dissolved in water. As expected, they dissolved. I dipped in some Al metal and saw that a brownish powder started forming on it's surface. I'm assuming the powder was Cu and the Al was replacing it in the solution. I've no clue why I managed to dissolve copper, but seemingly no NO2 gas was formed. Does anyone have an explanation for this? Also, any idea how I could actually produce nitric acid from the fertilizer that I have or should i just buy some KNO3?
