Re: Federal Blue

The Only thing we know for Certain is that thread in the uniforms sewn with Logwood dye thread DID change color from blue to brown as Documented in an Article in Scientic American , August 24, 1861 and In Ann E. Cordy's, "Investigation of Thread Color Change in American Civil War Uniforms", (Ph.D. Dissertation, University of Maryland), as she states that in an experiment "the logwood colour thread turned brown within ten hours of artificial aging with light versus no colour change for the Prussian and indigo with over 200 hours".

One of my Original Great Coats is Stamped "preserved by Cowle's Process, so I that that into consideation when looking at the sky blue color of that uniform....

Re: Federal Blue

Cowles's Process also included glues that made the fabric heavier, in addition to materials that fixed the colors. Whereas something used on a regular basis would loose a little bulk from wear.
