Horse Science · Hoof Science anatomy models have been freeze-dried in a vacuum chamber at sub-zero temeratures for at least four months. This process removes all moisture, preserving soft tissue for a very, very l-o-n-g time. No chemical preservatives are used.
Proper care includes keeping the model dry, keeping it away from dogs, and protecting it from household insects (moths) with a commercial clothing spray or by storing it in a sealed container with an insecticide. Scratches can be repaired with clear shellac. There is one other hazard. Friends and colleagues will try to borrow your model; have them call me instead!

The United States Department of Agriculture Veterinary Services has on file
a notarized affidavit from Horse Science verifying the accuracy of the statements
below:
1) Horse Science-Hoof Science equine and/or Bovine hoof/lower limb anatomy models
are prepared entirely in the USA.
2) Establishment of production: Horse Science-Hoof Science, 54 Oak Ridge Road,
West Boxford, MA.
3) Freeze-dried and skeletal lower limb anatomy specimens for educational use
are prepared from cadaver limbs from Domestic Animals only.
4) The limbs are soaked and washed in disinfectant solutions containing Sodium
Hypochlorite 5.25% (Clorox) and Dimethyl Benzyl Ammonium Chlorides 0.8000% (Lysol).
Specimens are promptly frozen and placed in a de-hydration unit where they are
held at sub-freezing temperatures (-20 degrees Celsius) for a minimum of 3 months
or until they are thoroughly dried. The finishing process utilizes small amounts
of denatured alcohol followed by finish coats of clear shellac and commercial
coat conditioner. The skeletal models are boiled (covered in water maintained
at 100 degrees Celsius for minimum 8 hours), then bleached with 100 Volume hydrogen
peroxide for a minimum of 12 hours, then coated with clear shellac. No other
chemicals or preservatives are used in preparing these models.
5) Horse Science hoof/limb models are for educational purposes only. They are
not for human or animal consumption. Product is not intended at any stage to
be diverted for any use in food, feed material, organic fertilizers or soil
