I am trying to match the finish on a walnut piece from the 1850’s. The wood is a walnut crotch veneer. the finish is shellac. The old walnut is much lighter than new wood. Any ideas on how to chemically lighten the wood?

Wood bleach is the standard technique.
Walnut reacts well to 2-part bleach. Use sparingly.

If you're not in too much of a hurry, walnut bleaches pretty quickly (within a couple of months) when exposed to sunlight.

Use a two part A-B wood bleach. A-B bleach is used to remove the natural color of wood. Use a dilute mixture and be sure to test it on some scrap before you ruin some expensive wood.
After you bleach you will need to put some color back.
I use Transtint Honey Amber for the tellow tone and then may need to add some Medium brown to get the little hint of garnet back.
I mix the dye with water to get close then add to shellac as a toner to bring it up to the final color.
You can also use yellow black and red dyes to make your own brown, which is helpful for hard to match areas. Blues and greens are also good for helping tweak the final color.

Bring it over here,, I have all of my exterior trim in Black walnut and it's a nice yellow right now.. I'll trade you for some fresh black to put up in place <grin>
