TJIPETIR Rubber Blocks Found

Rubber blocks have been found washed up on beaches around the world - and a woman is writing a book about her discoveries due to them arriving on European and UK beaches. It is written that the rubber material is at least 100 years old.

It feels like a message for humanity and I am wondering what that word means. It is written that they originated in Java - Indonesia and Java is also known for its pearls.

Its written that its the name of a rubber plantation. However - what does it mean.

The rubber itself comes from the sap of the tropical 'gutta percha tree'. And source link mentions how the 'gutta-percha latex is biologically INERT. Resilient and a good electrical insulator with a high dielectric strength'.
