Hi,
Brovira was available in very hard contrast, number 6 here in the US
and labeled 'extra hard' in Europe in the early 60s. Really nothing like
it before or since.

DEAR RICHARD,
Having attended RIT I had the pleasure of knowing many people who had
worked, were working, or would work for Kodak (Admin, professors, and
fellow students). They made it quite clear that they had always written
everything down but that everything was highly protected as trade secrets.
Someone who was in my graduate photo sci classes in the early 70s visited
Barbados a few years ago and retired from Kodak soon after. He decried the
banning of cadmium from photo papers because it seems that, within limits,
the more you used in the paper emulsion, the warmer was the tone without
post fix toning. Even though he had proved that none of the cadmium was
freed in the processing (tightly bound in the paper) they stopped using it
to avoid problems with the govt bureaucracy. Sad, really. I am totally in
favor of making our processes as "green" as possible but, when it has been
proved that nothing harmful would be released into the environment, they
should leave it alone. Oh, well...
CHEERS!
BOB

Agfa made some extremely interesting papers. I was also a fan of
Brovira and Portriga. I used the Ansco versions of these papers and later
when Agfa sold directly in the US I discovered that the papers smelled the
same. Agfa and Ansco had a very distinctive odor. They made some excellent
papers but could never match Kodak for uniformity of surfaces and lack of
frilling or cockling.
Ansco's version of Portriga was Indiatone, a slow, very warm tone,
projection paper that could also be used for fast contact printing. Toned
beautifully and was as warm as Kodak Opal. They also made an excellent
neutral tone contact paper called Cykon, IMO better than Azo. I am not sure
what the AGFA name was for it, maybe the same. Probably the warmest contact
paper I ever saw was Kodak Athena, almost brown without toning. I am sure
the secrets for making all this stuff were never written down and are now
forever lost.

Looks like B&H can get Foma special order....
(Speaking of old papers, I will never get over the loss of Bovira and
Portriga. Portriga in Kodak Brown Toner was chocolate on paper...)
