Thread: Scales material - best wood?

If you use a finish with UV inhibitors it will slow the change down some. I've worked with purpleheart that sat around for awhile that changed to a brownish color and I let it sit in the sun for awhile and it returned to a deep purple. The reason it changed back wasn't because of UV though, but rather from the heat. Some woods darken from heat while some it restores it. If your looking to darken woods oil finishes have tendency to darken woods while a water based finish doesn't. Check out The Wood Database it has a lot of info.
