So I believe your answer to my first question is that they don't paint
the bottom, they only use my scenario two -- soaking the leather.

About your parenthetical comment... If halakhah requires tekheiles,
it requires blue wool. The completed product would be what the kohein
shouldn't have a chatzitzah under. Not the undyed wool.

:> 2- If the leather is soaked in dye [until it's] absorbed and the leather

: 2. Why shouldn't it be valid material after soaking? It's still
: leather....

But it's no longer entirely skin of a kosher beheimah, as the dye
isn't made from skin. It is now a retzuah made of skin + dye. I
could see that either way, and am asking how we (or the posqim among
us) can just assume that this innovation is not a problem.

Just as tekheiles is different than tzemer, perhaps dye-soaked
leather is different in kind than leather. How did we determine
it isn't?

Thanks for chiming in. But could you kindly put your full name in your
email header or signature once in a while, so that people know who we're
talking to? One of Avodah's goals is to create chevraschaft, which is
difficult when people are anonymous or partially so.

Tir'u baTov!
