PMK solution B

[kev curry]

Ive been developing film today and the negs are looking beautiful, what a difference heating solution B has made to contrast! PMK negs rock! Time for tea
Thanks again.

My "B" eventually grew crystals, so I mix "B" fresh every time. 6gr/liter

That'll be 6g to a litre of PMK working soluton right? Just checking

Trying to get those crystals back into solution is a pain. I'm finally taking your advice Eric.

Eric,

Another solution (pun intended) is to simply mix your solution B in twice as much distilled water and then use twice as much when mixing your working solution (or, if you are a real stickler, you can subtract the extra volume from the water you start with). PMK solution B is a saturated solution and tends to cloud or precipitate when it gets cold or if you mix it with anything else but distilled water.

And, if you do have a scales handy, you can just measure out the dry chemical when mixing the working solution. Just be extra sure that it all dissolves completely before developing film.

Best,

Doremus
