[pure-silver] Re: Kentmere Kentona Weirdness

Cadmium has several actions, in addition to those you mentioned, it seems to 
have been primarily used for contrast control, mainly control of lax toes I 
belive.

Sorry, I cannot agree with you there.
Dave might be able to throw some light on this but it is a different company 
and a different product, and if this is a cadmium problem, then it is NOT a 
problem with cadmium, but with whatever the new formulation is, as this, I 
belive, is a cadmium free paper.

Maybe we could trade and you could try it out for yourself?

The Factory is no more. Production is now at the Harman site.
The material is being made with harman technology to emulate the Kentmere 
product as close as possible. Harman claims that with the exception of Kentona, 
and POP, all is well and customers are very happy.

BTW, Harman downplays it's interest in the Kentmere monochrome products, 
stating its main interest was in another product they made used in advertising 
for which they held the major market share of.

Hummm, that might hurt the feelings of Kentmere fans, but if you change that 
sentence to read, "Harman", they would agree with you, but point to equipment, 
scale and old technology as the explanation.

Yes, by all means describe the problem to Harman, and let us know what they say!
