[How they do that] Balanese Granulation

Hi all. Can anyone elaborate on how the Balanese do their
Granulation. I am told from a friend who visits the villages,
they work in very primitive conditions with out the use of kilns,
but instead use mouth blow pipes and I am told use a red mixture
made up from the Tamarind tree seed pod as their glue base.

Thanks in advance
