Crown Lynn New Four Digit Number Shape Codes

The four digit numbers were first used in 1964.

First number defines the type of ware:
1 -Castware [Utility ware except for jugs and vases]

2 - Artware [Cast vases, figurines, plaques, etc]

3 - Cups or ware made on cup jiggers.

4 - Flatware or ware made on flatware jiggers.

5 - Basin jigger ware.

6 - Cast jugs.

7 - Hand thrown ware.

8 - Ram Press ware.

The second number defines material of the ware:
0 - 5 Earthenware [1000 to 1599 = Castware, Earthenware]

6-7 Vitrified ware.

8 - Stoneware

9 - China?

These numbers make so much sense now that the Titian/Crown Lynn Gallery is making progress.
