DIA150xH40, China

A flat dish with a spout.

This is one of the items in the shop that I have problem finding out its use.

Spout – suggest the use for pouring out liquid, powder or beads?
Blue and white under glaze –  suggest a clear liquid (verse ink) so pattern can be appreciated?
Heavy & flat – suggest not intended to be handle often (unlike a teapot)?

If anyone has any idea how this item was intended to be used, please let me know!

If you are interested in solving puzzles, check out the other curious items; A Jade Tool, Paper Lacquered Tray.

Now back to the pattern; clouds and crane.  It is a popular ceramic pattern, it is believe that the crane is a mythical bird and symbolizes longevity.
