Cruets are the small containers that the wine and water are poured from into the chalice.
The value of a vinegar cruet depends on what type it is and how old it is. The value for older cruets in excellent condition would be more valuable.
If you are referring to the (usually) glass containers that the wine and water are poured out of into the chalice and used for the washing of the priests hands (respectively) then those are called 'cruets'.
In the Catholic tradition, the vessels that hold the water and wine to be poured onto the Chalice during Holy Mass are called the Cruets.
They're called "Cruets".
The site Chef's Planet has a variety of glass cruets for sale. One could also check Amazon and E-Bay to get a good price and varied selection of choices. The store Crate and Barrel also has a lovely selection of pretty yet serviceable cruets.
The mass/luminosity relation is important because it can be used to find the distance to binary systems which are too far for normal parallax measurements.
Vintage glass cruets may be found on eBay, Replacements.com, TIAS.com, GoAntiques, poshchicago.com, Amazon.com, Ruby Lane, Etsy.com, ArtFire.com, eCrater and Bonanza.com.
While you can use them for anything you would like to, in the majority of cases they are used to store vinegar, vinaigrettes or oil.
