Three months ago I received from a client in Canada a Greenland shark jaw
They had bought it in Iceland and brought it back to Canada.
I received the Greenland shark jaw in a pretty bad state. The jaw had discolouration yet the teeth are perfect.
I started soaking it over a 3 day period. The cartilage on the Greenland shark jaws is very thin, and easily damaged.
The Greenland jaw does not have good calcification, therefore will damage easily. It was then placed on the drying board and I applied my special whitening paste.
After around 2 weeks, I check if the jaw is dry. I can remove the jaw once completely dry and allow it to keep drying naturally.
It has now been 5 weeks, and the jaw needed to go back in solution as it showed slight warping on the bottom jaw.
Once it is fully dried, the Greenland jaw will be carefully examined for any holes or cracks, and these will be filled in with a special 2 part epoxy putty.
The jaw will then be lightly sanded to remove imperfections and examined to make sure it is perfect.
These Greenland jaws are best mounted on a board. Not only will this add to the visual appeal of this jaw, it will also ensure it will not distort over the years. Humidity is a real enemy of such jaws, and it will soften and deform these jaws.
The Greenland jaw will need to be dried for another couple of months, so as to ensure no moisture is left in the cartilage.
Once totally dried, it can then be mounted on the board. I use a 10mm black Perspex board to mount all my jaws. Such dark boards enhance the whiteness of the jaw.
