Yes, I have dyed deer antler with transtint dye/alcohol. It worked wonderfully! I use blue and it gave a nice light blue hue that did not look fake. I also stabilized some Axis antler from a deer that I killed while still in velvet. Once the velvet came off, the antlers were very porous so I cast it in Alumilite and got color and added density. Will try to post a pic one of these days.
