I'm currently making a quarter-plate wetplate camera out of Lacewood
which is sort of an organish-brown wood with hundreds of elliptical rays
that exhibit something akin to chatoyancy. Just last week my
woodworking instructor suggested I use potassium dichromate as a stain
to further highlight this effect. I may do so, but I think I'll sand
the wood first before staining it with K2Cr2O7. ;)
I just completed making the bellows for this camera yesterday. The
outer layer is copper Spandex. Funky. Keeps me off the street.
But, if the potassium dichromate is light-sensitive, wouldn't this
eventually darken the wood and/or turn it towards green in hue? Anyone
know?

Actually, dichromates were used by woodworkers for staining wood and in
some cases, as a preservative. Quite popular back in the day.
