&gt;I assume the &quot;Sodium sulfate&quot; is supposed to be &quot;Sodium
SULFITE&quot;...

&gt; &gt;
&gt; &gt; D-23 Developer
&gt; &gt;
&gt; &gt; Solution A
&gt; &gt; Water @ 49oC 750 cc
&gt; &gt; Elon (Metol) 7.5 gm
&gt; &gt; Sodium Sulfate 100 gm
&gt; &gt; Water to make 1000 cc
&gt; &gt;
&gt; &gt; Solution B
&gt; &gt; Water @ 49oC 1000 cc
&gt; &gt; Kodalk (sodium metaborate) 10 g.
&gt; &gt;
&gt; &gt; Use distilled water
&gt; &gt;
&gt; &gt; Immurse plate in solutioon A for about 5 min. at 20 o C
&gt; &gt; Agitate for 5 sec every 30 sec.
&gt; &gt;
&gt; &gt; Then immurse plate in solution B for 3 min. at 20 oC
&gt; &gt; Agitate for 5 sec. every 30 sec.
&gt; &gt;
&gt; &gt; Agitation is very important especially in solution B or streaking
&gt; &gt; will occur.
&gt; &gt;
&gt; &gt; Note that 20 oC is room temperature. I have found that the times
and
&gt; &gt; temperatures are not critical.
&gt; &gt;
&gt; &gt; Other sources suggest a developing time of 9-14 minutes in A and
&gt; &gt; 3 minutes in B.
&gt; &gt;
&gt; &gt;
&gt; &gt; Good luck with this.

&gt; &gt; &amp;gt;&amp;gt;Since it is independent of time and temperature
(more or less) I
&gt; &gt; &amp;gt;&amp;gt;believe I would try a two-solution developer such
as DIAFINE or
&gt; &gt; &amp;gt;&amp;gt;D-23 which is no longer commercially available but
I can give you
&gt; &gt; &amp;gt;&amp;gt;the formula if you want it.

&gt; &gt; &amp;gt;&amp;gt;&amp;amp;gt;This question come up to me as one
friend bought old
&gt; &gt; &amp;gt;&amp;gt;platecamera and
&gt; &gt; &amp;gt;&amp;gt;&amp;amp;gt;it included several exposed dryplates
undeveloped. They
&gt;are
&gt; &gt; &amp;gt;&amp;gt;some
&gt; &gt; &amp;gt;&amp;gt;&amp;amp;gt;80years old. How he should develope
them?
