After cutting purple heart wood I noticed the edges were very purple but the rest was less than. Which got the grey matter churning a little.
It had to be heat buildup that caused the colorr change. I did a test on a scrap piece….I covered part of the scrap and heated it up with a heat gun. The second picture shows the outcome.
No stain used, only 1 coat of finish.
I covered the stick below the butterfly and heated only the butterfly.
Anyway I thought it was much more colorful using this new found method.
Thanks for the peek.

It also oxidises, and as it ages, the bright purple darkens quite a bit. Didn’t know about it’s reactivity to heat. Cool.

Pretty cool. I wonder if you could make a gradual shading with the heat.

That definitely opens some possibilities. Always like new techniques.

Great job on the butterfly.

Might shading with hot sand, similar to what you do for inlays.

I live in south Florida. I let the sun heat the wood. A few days of 90+ temps gives it a very deep hue as well.

Thanks for the tip. I was thinking of getting some purple heart and trying a project with the wood.

Good thing to know

Yeah, i believe the sun does it no matter the temperature, but i didnt know just the heat would work. I thought it was the UV rays. Maybe IR rays too.

Makes me think about other types of wood and the color change.
I like the idea of heated sand…I must try that method.

Everyone says it was pretty COOL but I read you used heat from a heat gun … does your heat gun put out cold heat? chuckle

I like what you have discovered and it answers some questions about my last purple heart project!

Neat technique… I’ll give it a try someday. Be sure to use a finish with a UV blocker to keep the purple color for as long as possible.
