Henriot Quimper France 4 Slotted Ceramic Hand Painted Ashtray 3.75" Vintage.  Height is .5".  All of the marks around the edge look like natural flaws to me.  I may be wrong and they could be paint chips.  It looks as though this is how the paint dried.  Regardless, it gives character.  There appears to be other paint wear.
