The marks in this thread consist primarily of geometric shapes--dots, lines, polygons, circles, ovals, and other assorted "squiggles"--not yet identified.
If you can identify a mark, please notify the Moderator.
See also 2b, 3b, 4b, and 4c. No. 3 is probably a Japanese mark--the flower form at the top looks like the usual stylized form of a cherry blossom, though seated on another geo form--but the other forms are not clear references.
See also 11b and 12b. Mark no. 10 is thought to be a Thai mark; No. 11 is a contemporary Russian mark. No. 12 is actually a Polish heraldic charge--the Odrowąż--and may indicate either the national origin or the name of the potter.
