Henk,
What a neat store!!
One more point: in the Cornelissen catalog,
all the colors I have mentioned are PR101...so Henry, searching for PR101
in Wilcox or Hilary Page might help you.
When my mom died I inherited all of her old oil
colors. What a motherlode, many tubes 60 year old. Prices at 65
cents, cobalts a dollar or two! Now defunct pigments as well such as
Emerald green. Unfortunately no watercolors but I was able to see what was
in vogue then. Mars red is not that dark of a red when diluted, of course,
as it looks like in the Cornelissen catalog but I don't remember that name
coming up in any gum research so it is probably more recent.
If I lived near Cornelissen or Verfmolendekat
I would get into serious financial trouble...
One very interesting thing in the catalog as
well--the weight of pigments is from 3 oz. to 0.3 oz (cad red former, lamp black
latter) volume to volume.
Chris

package with their stamp on it, so i will contact them .
Keep you informed.

Here at Cornelissen:
you can download their incredible
catalog. On page 3 there are some reds displayed, red ochre and red
oxide, also Mars Red I forgot about, but I don't ever remember that name
(Mars) in all my gum research and do remember the oxide and ochre...they are
orangier than what one considers a normal red. A brick
red/orange.
In looking up conte on Wiki it comes up with
the fact that the crayons were a combo of clay and such...boy, if you live
in South Carolina the bright red clay dirt down there would be glorious for
this kind of gum print. Don't ever try to hike up a clay mountain when it is
raining--it is slipperier than an oiled pig.
Keuhn really liked this color as well, if I am
not mistaken an example or two of his red gum prints are in Impressionist
camera. Another example of photography trying to imitate art I
suppose.

Hi Chris et al,
Maybe you remember the two images i send sometime ago:
an oilprint versus a gumprint.
For the gumprint i used a pigment 'kalkrood' (must be clear that it
is 'chalk red').
cheers,
Henk

Red, and Sennelier red ochre.

Chris,
I think you are right. If I
remember, the Red Chalk or Sanguine was a special chalk that had a lot
of iron oxide in it.
Were the Demachy prints in this
color gums or photogravures?

Henry,
Try Venetian red, Indian red, or red
ochre. It was a red iron oxide pigment if I remember
correctly. One recipe calls for 3 g. Venetian red powder to 1/2 oz.
gum. Another calls for a pigment called "light red" which I know was
available about 10 yr ago anyway. But Venetian Red is a nice
brick-y color that you'd be happy with. My notes say
this: "For
instance, a Venetian red or red ochre color was used to
approximate the rust colored conte crayon
portraits."
