"purple heart will turn purple due to heat or HCL or other acid - if you
don't believe me, try it. colors are different but both are arguably
shades of purple - the HCL is more red, the heat more blue in my
experience


I have had purple heart turn both brown and stronger purple when cutting
different pieces of purple heart.

What I would like to know is how to turn the piece that turns brown with
heat, back to purple, what kind of acid?


Ah... HCL got it.
