<p>[QUOTE="V. Kurt Bellman, post: 2118293, member: 71723"]Thank you, Lehigh. I've been discharged from the hospital and I'm Amtraking to work right now. That rainbowed '64 Jeff does bug me a little though. Call it a fetish if you want, but why does the rainbow's plus factor wipe out the minus factor of the "crud" in front of, and especially behind ol' Tommy Boy? To me, there are competing factors here and it rates a PF67? Wow. Tough for me to take that seriously.</p><p><br /></p><p>I'll warn you up front that my "lab" is an ordinary rurally located rancher kitchen, not something out of a Grade B movie with Jacob's Ladders and Vandegraff machines all around. I do own one Bunsen Burner, but it doesn't figure in. It's mostly boring retro darkroom tools and chems. To be square with you, contrary to the thread title, the easy stuff to fake is what I call the "brown splotchy" toning, which is getting premiums I just don't understand. Rainbow requires different techniques, and is fairly hit or miss. I am suggesting here that there HAS TO BE somebody better at this than I am, if because of better equipment if nothing else.</p><p><br /></p><p>I ran into this completely by accident, because after thiourea/citric acid dipping, I use a baking soda bath to fast stop the thiourea/acid before the distilled water bath. One time I accidentally put the baking soda in with the thiourea, and got wild tones. Most unattractive, at least to my eyes, but some really neat! I often see stuff like I got in slabs with gaudy grades.[/QUOTE]</p><p><br /></p>
