Red Chalk was also a color used by many of the early bromoilists for portraits and sometimes for landscapes. I have a tube of pre WWII Drem Company (Vienna) bromoil ink labeled "Red Chalk."

Cheers,

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."
