The process of restoring such a shark jaw is a long and painstaking one.
Jaws may come to us in bad condition due to improper storage, which, because they are cartilage, may also have developed very bad cracks and holes. Another common problem is discolouration and hardening of lacquer or varnish. Ironically although this very hard to remove, it does in fact protect the cartilage below, thus ensuring the cartilage will be successfully whitened when it enters the whitening solution.
Once the jaw is received, it is photographed and examined carefully and the extent of the work is assessed and quote provided.
The jaw is then washed and placed in the whitening solution where it may stay for up to 1 week, sometimes more.
