so are you saying it cost $100 in materials? or that you are worth $100 an hour? I cant think of anything that would set the cost that high unless you were using uranium or platinum
My time
. And that was 30 plus years ago. I still have reagent grade silver nitrate, I paid 80 USD a pound for Eastman silver nitrate (that was a commercial account price 24 1 lb bottles at a time).
I should have bought Palladium when it was 60 dollars an ounce, my friend did. I gave away my uranium salts, not a healthy toner.
I made a batch of silver nitrate a couple years ago, nitric acid, fumes will kill you, don't breathe.
If I run out of gold chloride I will make more. I love gold chloride.
Adox makes lovely silver chloride paper.
