Fish leather is generally
around the same strength as sheep skin. However shark leather is
anywhere up to 6 times the strength of a standard land-based leather.
Unfortunately 70 - 80% of
fish colour is contained within the scales, which are removed in the
tanning process. The result is a neutral coloured skin that is suitable
for dying any colour.
Tanning is a process that
changes the fibres of any skin, through use of a "tannin", into leather
fibres. The skin changes occur both internally and externally.
Glazing is a specialised
leather process to add a protectant to the outside surface of the
leather to protect it from dirt, grease, grime, and excessive wear. It
is a polymer resin that is sprayed onto the surface of the leather,
allowed to dry, then plated down with heat and pressure to make the
leather water-resistant, drycleanable scotch-guardable and washable.
Many others have tried to
make fish skins into leather, and few have succeeded. We have been able
to take out fish oils, and substitute chemical oil, leaving no odor.
Anything that a normal land
based leather can be used for. Our leather has been used to make shoes, handbags, belts, hats, wallets and other apparel and accessory items. It has also been used for jewellery and book binding.
The benefits are both ecological and economical. By reusing
these skins, we are recycling what would otherwise be thrown
out. Fishkins are less of a pollutant than other leathers because only
the scales need to be taken off.
