What do #s mean on

Cobalt blue glass? I have a few pieces that have numbers on the bottom.

Thank you for reporting this comment. Undo

What kind of cobalt blue glass? How are the numbers put on?..etched, impressed in the mold or raised?

Early opaque glass ( AKA milk glass) was 'marked" with a number on the bottom of the piece. And this opaque glass also came in a blue...but more of a sky blue than a cobalt.
How about a picture?
