hi - your 'pouring bowl with spouts' is a fairly standard shape of 'wine glass cooler/rinser' - these were included as an item of table ware, and would have been provided for each diner, in which the wine glass could be cleaned and kept cool ready for the next drink.
Until about 1840/1850 ish, diners were provided with a single glass only for all of their drinks, so possibly the sediment or lees might have accumulated without this rinsing. After this date, it seems that the custom of hving a different glass for successive drinks became the norm.
Their heyday was probably the late C18 and C19, although earlier rinsers seem to have been in clear glass and had only one lip, and these coloured ones probably date more to roughly the first third of the C19. Having said all that, like most things copies have been made in the C20, so wise to look at the wear, weight, thickness etc. - I'd have thought this one was right, but the screen is not always reliable.
Rinsers might have been a substitute for a finger bowl, as well, although finger bowls didn't have lips like this one, on which the stem of the wine glass rested (obviously the glass was inverted, and the bowl placed in the water). This example is probably a C19 piece - according to the books the earlier ones had one lip only.
Sorry, but can't help with your other piece.
