I’ve noticed that Battern’s flux appears
to be light sensitive as the color fades over time. Does anyone know
if this fading affects the working abilities of the flux?
G’day; I don’t have Batterns flux, but I would hazard a guess that the
blue colour consists of an organic dye, and it is blue simply because
when it was first formulated someone though it looked more interesting
than a colourless liquid. Inorganic colours don’t fade with light. Which
is why I suspect dye.
I doubt whether the faded material would be any different in use than the
original. Incidentally I make my own hair gel which is colourless, and
put in a drop of food blue ‘to make it look more interesting’! There’s a
pennorth if you like! Cheers,
