When Dyes Bleed

Quite a while back I was given the task of restoring an old quilt rack made of mahogany, circa 1880's, in the Eastlake Victorian style. Most of the finish was in terrible shape so I
went about stripping the old finish completely off and while doing so I found what I believed
to be the original color on the underside of the feet. It was a very rich and deep red mahogany
that was bordering on "purple" or what we used to call "eggplant."
I called the customer to tell them what I had found and I asked if they want the original color or a lighter version? They
settled on a color slightly lighter but still a little on the dark side. I mixed up some
lacquer/oil based aniline dye and applied several coats to reach the color I was after then
finished the piece with nitrocellulose lacquer.
A couple of weeks later the client called to say the colors were bleeding into her fine linens she had draped over the rack. I was horrified. Not
only did I have a problem but how much were those linens worth? Or, were they family
heirlooms? Reassuring the client I would take care of everything I brought the piece back
to the shop and called a friend for an explanation. It was very simple. The dye I used was
lacquer/oil soluble and the lacquer finish I applied "pulled" the dye out of the wood allowing
it to migrate through the finish and therefore transfer to the linens because there was no barrier
coat between the dye and lacquer finish. To take care of this my friend said all that I had
to do was apply a couple of coats of 2lb cut shellac as a barrier and then topcoat with a coat
of nitro lacquer. Problem solved.
Fortunately, I worked at a dry cleaning plant in high school
and learned how to "spot" fabrics to get out stains before dry cleaning. A cleaners down
the street allowed me to use a steam table and with a little mineral spirits this thankfully took
care of that problem as well. I never thought my dry cleaning experience in high school would ever
get my butt out of the proverbial sling but it did!
