These 3 metal vases are called situlas and form part of a set used for drinking wine. You can just see the edge of the associated wine strainer at the left of the picture (wine in ancient times had more solid bits than it does now, so you strained it like you do loose tea today).
They are rather beautiful, as well as being made of precious metals (silver for the rear two, electrum in front and gold for the strainer). As well as elegant shape two of them are also decorated around the rim and one at the base with leaf and flower motifs.
They were found in the temple of Bastet at Bubastis as part of a collection of objects that had been buried in antiquity – probably because they were no longer in use for rituals but were still considered sacred so couldn’t just be binned.
The rituals they were used for were probably Festivals of Drunkenness which became a particular part of the worship of Bastet and other goddesses like Hathor in the New Kingdom (which is when these vessels date to), and emulated the drunkenness that pacified these goddesses.
They are now in the Met Museum, acc. no.s: 07.228.17, 07.228.18, 07.228.22 (and 30.8.369 for the strainer).

I have re-told the story of Sekhmet and her rage being pacified with booze (in that case beer) on the blog before: https://talesfromthetwolands.org/2019/07/11/and-she-blew-through-the-towns-like-the-hot-desert-wind/
