Clean-a-Jaw has just received a couple of jaws from a Mako and a Tiger I did back in 1995.
The client, Vicki Winter-Lear is an avid fisherman and is heavily involved with all aspects of sport fishing in Australia.
The jaws appear still to be in very good condition, due no doubt to how and where they were stored. Certainly they have acquired a certain “aged patina” over them, though nothing too bad.
if jaws are processed, cleaned and preserved properly, there is no reason why they should not withstand the test of time. Humidity is the worst enemy of cartilage. If jaws are left in a humid environment, eventually apart from mild, the teeth will slowly start detaching from the jaw and the jaw itself will start to rot.
Proper preservation when the jaw is initially cleaned and storage of the jaw, is vitally important to ensure the jaw is kept in great condition for years to come.
Luckily, these jaws will need minimal work to. E carried out on them. The old patina will come off after a period of soaking in my solution, and then they will be re-set on the drying board and dried again.
The Tiger shark jaw will need a bit of re-shaping as these jaws are quite thin at the joints. The Mako instead has got a beautiful shape and hasn’t changed since 1995.
Once these jaws are cleaned up again, the dust has been removed and the cartilage whitened again, they will last another 20+years.
