Fritz Otto Goes Fishing 2

In the last installment, Fritz Otto Goes Fishing, our hero prepared the fish skin for making parchment, but also trying something new, egg tanning. We're following Nienke Hoogvliet's instructions from her book Fish Leather. Ready? Here we go! Fritz Otto is glad @bookbinderbarbie left copies of her notes.

Taking one of the haddock and stretching it out to make parchment.
We'll compare with the egg tanned haddock.

All right, that's done. Now to let it dry.

Now, on to the egg tanning!

Why do I always get the grunt work? Beat the egg, oil, detergent mixture until smooth.

Next, tamp the haddock and salmon so that they are not dripping wet.

At least I didn't have to drop the skins into the egg/oil
mixture to then massage it into the skins until warm.
That looked totally gross!

But, wait! I get roll up the slimy skins so that they can sit for about 15 minutes.

Now we hang them up to drip-dry.
When dry, they'll still feel oily/slippery, and we'll need to massage and work them to
loosen up the fibers in the skin. We do that for a week.

Here they are a week later. Time to rinse in soapy water until they
feel soft and not oily/slippery.

Rinse, and rinse some more...

Let drip-dry. We tamped with a paper towel again, too.

Then, dump them into a more dilute mixture, work in, and set out to dry.

We smoothed them out to dry on a piece of plexi-glass,
scale-side down. That gives them a shinier appearance.
When they were dryish, we worked them back and forth
over a smooth dowel, always with the flesh side to the dowel.
Finally, we worked it like leather before paring.

Take out the pins and liberate the haddock parchment. Next we'll compare.

Comparing the haddocks – parchment at the bottom, egg tanned at top.
The egg tanned is like parchment, but much shiner and more
transparent. Not sure how we feel about that... The whitish patches are
fleshy stuff that will need to be scrapped off with a scalpel later.
The haddock is much more thin-skinned than the salmon.

See what I mean by transparent and shiny?

And here the egg tanned salmon. Less translucent than the salmon parchment that was made
when @bookbinderbarbie was here over a month ago. Softer too, but not supple like leather.
Still. looks and feels really interesting. Wonder if we'll make anything with it?
