I recently was givien about 16 oz left over from a 32 oz bottle of this Flo-EZE Brilliant Carmine from Caldwell Ink Co. This bottle has a very old look to it, similar to the 1920's bottles. It says non corrosive and unaffected by steel pens. Does anyone have any information on such ink and the company before Caldwell became a printing company for present printers?
Is it ok to use on fountain pens?
The bottle states that it is from San Francisco and Oakland with a quote saying "Made in California under the most favorable climatic conditions in the world."
I looked all over online and not a single picture or clue to this type of ink.
