As I have commented previously, more than once, at the present time everybody wants to stick a tangguh on everything, and this is not at all what the system was originally designed to do.

I have seen many-many times, what we called "experts" failed to date already known old-keris
on one occasion, one "expert" from Malang is being shown 5 betok keris and he is told in the beginning of the "game" that from 5 keris presented, 2 are original and 3 are fake ... and he failed to point the original one.
I myself have already asked and shared opinions with many person and still thinks that tangguh is somewhat very difficult to discern, a person must have broad knowledge of keris type and characteristics of keris from many areas, possess enough knowledge on metallurgy, have personally handled many many many blades by himself and have direct experience from known master/s to enable himself to provide "non binding" recommendation on how old the blade is
and even then he can still made mistakes
so I came to a conclusion that to have more than 80% of success rate on determining the tangguh, we need to dedicate our lives on this subject
lastly, can we use radio carbon dating to date a keris ?? I have read several papers that this method can be used to determine age of carbon steel materials down to acceptable level of accuracy
