Wee Break Coming Up
I'm about to go off on a trip to get the other eyeball sorted out. I haven't managed to finish a conductive slide, and won't be able to play with boiling acid, sprays, etc. for a couple of weeks, so expect a break from my usual tedious updates.
I have realised a mistake in my sums, and need 4x the quantity of acid I previously thought. Also, it has become apparent that tin does not dissolve in 24% HCl unless it is heated to above 60C so leaving it to sit overnight doesn't help. When I get back, I'll repeat the experiments with the stronger tin chloride solution.
Meantime, I might be able to work on the Z Touch software one-eyed when I can.
Might try my luck ordering some lab grade tin chloride, but due to "backyard alchemists" having a history of brewing illicit substances in New Zealand chemistry things are difficult to get. Believe it or not separating funnels are restricted items here, for example!
