I was tempted to re-japan with this stuff

My 1927 edition of Henley's Formulas For Home and Workshop has this
for Japan Black.

12 oz amber
This is the stumbling block - the price of amber resin must have gone
up quite a bit, relatively, in the 80+ years since the book was
published.
2 oz asphaltum

Here's a liquid version, but Henley's is probably referring to the
solid.

Fuse by heat and add 1/2 pint boiled linseed oil and 2 oz rosin.
When cooling, add 16 oz of oil of turpentine.

One day I'll make some. Sometimes I'd rather spend the same amount of
money (and not put a price on my time) just to do something new that's
old.
