re: Ebonizing

Ron - thanks.  It is kind of a fun science experiment watching the color change.  Regarding the Rubio sheen - I do think that there is a wood species component.  Or perhaps a dependency on hardness.  The frame had been sanded to 180 prior to applying Rubio, and with one coat it does have a nice sheen.  The cherry stool that I built recently was sanded to 220 and required two coats of Rubio to achieve the same sheen.    I'll probably apply a 2nd coat to the cabinet frame just for good measure.  I'll wait a day or two, scuff the surface, and apply.
