Not surprisingly I don't agree with Sandy's assessment. Firstly, the cost of the paper for a 12x20 print is roughly 50% of the materials cost per print. So assuming Sandy's 1/5 cost is correct for the sensitizer, a 12x20 pt/pd print will cost me $4.25 and the same thing in a toned kallitype will cost $2.50. The Kallitype is about 2/3 the price of the pt/pd print, not 1/5. Just want to clarify that...

But the hands-on part of the processes are very personal and we are each drawn to different processes for different reasons. For the way I value my time, pt/pd printing is much less costly than Kallitype. Spending a couple extra bucks to make a pt/pd print vs. a toned Kallitype is money well spent, in my opinion.
As for the Sandy's archival claims, I'm skeptical but have no hard data to disprove him. Over the long haul, will a toned kallitype be as archival as pure pt/pd? Who knows... And, frankly, I don't really care. I'm just saying I'm not sure about the archival issue. In then end it's the look of the print that counts, and hopefully it will have a long and appreciated life! I'm not one of those a "archival freaks". I want my prints to last a long time, but don't obsess about it.
I'm not trying to say Sandy is 'wrong' on any of this. I respect his abilities and dedication to what he is doing. Clearly he is knowledgable and does what he does well. I simply want to point out that there are different ways to evaluate the cost of a process than dollars and cents.
To be successful at any of these processes, you really need to enjoy doing them. I love pt/pd printing... I love gum printing... I'm now working with wet plate and loving that as well. Kallitype for me was a PITA.
