Hello! I built a custom lichtenberg kit and attempted the burn. The solution I used was water and baking soda on 10ft Cedar planks. The burns came out great, but because I used a brush for the water and baking soda often to help make a path for the burn, the ash from the burns darkened the wood in different places and it looks splotchy. If I sand it, it damages the burn design. Any idea for restoring the Cedar to its natural red look without sanding/destroying the lichtenberg burn design??

This is a reminder to others that Lichtenberg burning is extremely dangerous.

-> More than a few woodworkers have died while attempting it, due to the high voltages involved. It is so dangerous that some woodworking sites have banned discussions about it altogether. Do not underestimate the risks, which include death.

The point of this message is to leave a warning to others about Lichtenberg burning. Many people who felt that they were following the best safety practices have been hurt or killed. This message is not for @InOverMyHead, but for others who may be considering it.

... With that note, I return you to the discussion about how to clean up those dark areas.

It's a free county, and most of us are adults here. I hope that @InOverMyHead has performed a careful and serious assessment of the risks involved. In addition, I hope that their choice of member handle (name) is not prescient. :-(

No worries with the wood burning process. All of the proper steps and more were taken when doing the burn. I’m more of an engineer than a wood worker/carpenter. With rubber padding, rubber gloves, safe zones when powering on, and controlled environment were all taken very seriously.

How thick is the wood ? Could you chalk this one up to the learning curve, sand it all off, and do it again ?

and to emphasize the topic: this thread is about the wood discoloring - not the process used.

I was thinking of doing that as a last resort, the burn marks go about a 1/4 inch deep. Wood is about 1 1/2 inches thick. I don’t have a planer available at the shop I’m at, would hate to power sand it all.
