Where to find and how to get all drops of tears? (Elden Ring)

I found 12 pieces, that is, a flask at least, and maybe even as a maximum +12

In the third temple of Marika, there is a customizable bottle that can contain up to two tears with different effects. After selection, it is adjusted when resting at grace - "mix the potion". In the third temple of marika there are two, it seems, tears. One for 50% heal, the other for an explosion. The rest have different effects, for example, the restoration of some more HP over time, or a temporary increase in some stat. Drops fall from the bosses near the small trees of Erd.

Don't you confuse drops with bowls? To improve the flags, seeds are used for the quantity and bowls for the strength of the flask. Tears for another.

Tears are mixed on a fire in a bottle. They mostly drop off the guard tree.
