McMaster has machinable wax in blue and purple colors, their site doesn't
mention the difference between the two color types, are they different
hardness? I'm gong to be machining a pattern on my Bridgeport mill and I
guess either one would work. Any suggestions? After I get the pattern
done I'm going to use it to make several copies in resin and then use those
for a Al casting pattern on a match plate.

Thanks
