this is a tannin bath .this kind of tannin is food grade the one used in winemaking and other edibles. it's a blend of quebracho,chesnut and tara and it's soluble in water.of course the crafty dyer knows that this is prime material for dyeing, albeit the shopkeeper's weird look.
and now the discovery. i/we were under the assumption that silk needed to be scoured in order to remove the sericin so that it could dye. not what i found.the top silk sample boiled to a glaring matted mess, glossy though,dyed much lighter after an overnight soak.the bottom one albeit still stiff is much darker.looked around for a proof of concept and ana lisa hedstorm has been dyeing without removing the sericin for quite a while.
the quid pro quo would be gloss,softness and a lighter color or stiffness and a greater color intake. cast your votes.
doing a test this week with mordanted threads to see what happens.
