Re: Developing dryplates

D-23 Developer

Solution A
Water @ 49oC 750 cc
Elon (Metol) 7.5 gm
Sodium Sulfate 100 gm
Water to make 1000 cc

Solution B
Water @ 49oC 1000 cc
Kodalk (sodium metaborate) 10 g.

Use distilled water

Immurse plate in solutioon A for about 5 min. at 20 o C
Agitate for 5 sec every 30 sec.

Then immurse plate in solution B for 3 min. at 20 oC
Agitate for 5 sec. every 30 sec.

Agitation is very important especially in solution B or streaking
will occur.

Note that 20 oC is room temperature. I have found that the times and
temperatures are not critical.

Other sources suggest a developing time of 9-14 minutes in A and
3 minutes in B.

Good luck with this.
