You would make good money by just peddling the bottle themselves for majority of history. Glassware, fine China and other vessels that can contain your dyes are not cheap before the industrial revolution.
No, not that much, they knew how to make glass since way long ago. I guess in the Americas you could, they apparently either had not much glass or it wasn't viable (like the wheel, which was for children's toys mostly).
I've always wondered how things would have played out in the americas if someone had invented something like the Chinese wheelbarrow[1] which is meant to work something like a human powered cart.
