[Histonet] Softening Calf Hooves

[Ingles Claire]

Sandra:
We here at the Dermatopathology department of
UW Mad have found:
-10% Potassium Hydroxide works best for us on our nails.

-We usually only need to have it in solution for a few hours. As you are trying to soften hoof, I might play with both concentration and time in solution.

- I don't believe Monty Python ever actually stated the relative air speed of either type of unladen swallow. 😉


Say HI to Vicki K for me.

Either potassium or sodium hydroxide will work at 10% aq. solution. Check it daily until soft enough.As to your "swallow" question, I "Goggled" your question and the answer is the following"
In the end, it's concluded that the airspeed velocity of a (European) unladen swallow is about 24 miles per hour or 11 meters per second. But, the real question is not about swallows at all. King Arthur in the movie had two coconut shells that he banged together to simulate the sound of a horse galloping.Jul 7, 2013

 Hello all,
                I have 1 inch thick cross sections (band saw) of calf hooves. The pathologist has already decaled the bone, and now we have to soften the hooves so she can take thinner sections for processing.


*        Which is better, potassium hydroxide or sodium hydroxide, and what concentration?

*        How often should they be checked for softening?

*        What is the relative air speed of an un-laden swallow? (European)

Thanks for your help!
Sandy
