Easton's 1897 Bible Dictionary:

Laver
   (Heb. kiyor), a "basin" for boiling in, a "pan" for cooking (1
   Sam. 2:14), a "fire-pan" or hearth (Zech. 12:6), the sacred
   wash-bowl of the tabernacle and temple (Ex. 30:18, 28; 31:9;
   35:16; 38:8; 39:39; 40:7, 11, 30, etc.), a basin for the water
   used by the priests in their ablutions.

     That which was originally used in the tabernacle was of brass
   (rather copper; Heb. nihsheth), made from the metal mirrors the
   women brought out of Egypt (Ex. 38:8). It contained water
   wherewith the priests washed their hands and feet when they
   entered the tabernacle (40:32). It stood in the court between
   the altar and the door of the tabernacle (30:19, 21).

     In the temple there were ten lavers used for the sacrifices,
   and the molten sea for the ablutions of the priests (2 Chr.
   4:6). The position and uses of these are described 1 Kings
   7:23-39; 2 Chr. 4:6. The "molten sea" was made of copper, taken
   from Tibhath and Chun, cities of Hadarezer, king of Zobah (1
   Chr. 18:8; 1 Kings 7:23-26).

     No lavers are mentioned in the second temple.
