RE: Information on cutting hard tissues
From: | Jim at ProSciTech <jim@proscitech.com> |
I must concur with our Samurai and add to watch out that all of the nails are
removed too.
I am surprized that TC will not cut the hoof, maybe that horny material is
tougher than and certainly as hard as bone. You now have two options:
"Find" a fine diamond wire saw. The best will cut and "polish" in one pass and
take section under 30 um - though that may be a big ask with such large
sections.
The other method, I have previously mentioned on this list, is to take your
sections to a Geology department or a business that cuts petrographic sections
for mining and other companies. They will grind the specimen flat, Araldite it
to a large slide and then cut off most of the remaining hoof. After that they
grind and polish the specimen down to 30um or considerably less.
To do a whole hoof cross-section would be a work of art - I think I know
somebody in our town in Australia who could. Smaller sections would be
infinitely easier.
