Many of these beads have been found in the East of Java, both surface finds and excavated. They also have been found in Megalitc stone graves.In indonesia they are called manik-manik Jatim. wich means beads from east Java. Jamey Allen (with Sumarah Adhyatman) has written about them in his book Magical ancient beads.http://books.google.com/books?id=dWuVjXZemO4C&printsec=frontcover&hl=nl&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
It is one of the few books about (amongst others) old Indonesian beads. As he mentions in his book most beads are made in the millefiore technique. A cane with millefiore design, surrounded by the same colour as the base of the bead is applied on the still hot core of the bead, thereby "melting" the outside colour so that only the design is still visible . Another good, if not the best source, is the book called "manik manik di Indonesia". Written in 1993 by Sumarah Adhyatman, co-, wrighter of Magical ancient beads, and Redjeki Arifin.The book manik manik di indonesia is a collectors-item by itself. This is as far as i know the only book that only handles old indonesian beads.
