The last chemical on which I would scrimp is ferric oxalate. Way back when
the only sources were outfits like Elegant Images and regular chemical
suppliers, the quality was shoddy at best and poor D-Max results were the
norm. I seriously thought about making my own but then came Bostick &
Sullivan. I was happy ever after.
Now, if you can make the same quality, year after year, for a lower price,
along with good technical support, you might have a sizeable market.
