Thanks, Shinji, for the information about the duck pendants. I haven't seen any like them in Vietnam.

I've been several times to East Java but mainly to Trowulan, trying to figure out a chronology for the ceramic production there, never till last year to Jember. I didn't really go to buy beads (though I did end up buying a few from villagers I met who wanted to sell them), but mainly to find out more about where and in what conditions they were found. No real conclusions, since they seem to be quite widely dispersed, occasionally in dolmens like the one in the first photograph, sometimes in burial urns, but most frequently loose in banks and drainage ditches at the edges of fields and woodland.
