Thanks Kronckew,
I used 30-60 crushed glass on the square above, and I think it is too aggressive to use on a sword. I will experiment with the glass beads next. In this thread (
http://www.vikingsword.com/vb/showth...t=sandblasting ) it was suggested to use coal slag 'black beauty', wouldn't that be more aggressive than crushed glass? Has any one used it?
Atlantia, the appearance is very similar to a vinegar etch, with a flat dull grey appearance to the metal. I think that is more a result on the oxidation below the original rust in this case? You are also right that the result took only a few seconds and is actually more controllable than a vinegar etch.
Thanks
Jeff
