"relic" was originally called "relic" and later called "relic". This relic was originally translated into various names in India, such as (Establishment) ..., that is to say, the relics (relics) or (spiritual bones) were not obtained entirely by cremation, but also by chanting, worshipping Buddha or combining the relics with the aura of heaven and earth.
The "relic" is the crystallization of personal abstinence and wisdom. It is also a witness to the achievements of practitioners and can strengthen the practice of disciples. Therefore, when Buddhists see the Buddhist relics, it is like seeing the Buddha and Bodhisattva, worshiping them and offering them sincerely. But before nirvana, the Buddha told his disciples not to pay attention to his Buddhist relics, but to "Dharma Buddhist relics", which is a classic that integrates his words, deeds and examples.
There are many kinds of relics, and the real relics are extremely hard. If you hit them with a hammer, the anvil will sink without any damage. Colors are not necessarily, and different colors have different meanings. There are also some flaky colored lumps, which are easily broken and called residual flowers. You can see a lot in the later video.
I am lazy about sarira's explanations and stories. You can see the following links with pictures and texts.

"Zhou Fengchen lies the body of a man."
Anyway, for two years, there is no protective measures at home, but there is no variation. Natural glaze is really unexplained by current science.
Scientists explained that this may be the stone and mineral deposits of long-term vegetarians. But this conjecture is obviously untenable, because after cremation, a small number of relics are usually found on bones, and so many relics appear after the death of Dade, indicating that the relics cannot all be mineral deposits (such as the female layman in the first video). There are many people suffering from lithiasis, and the stones are mostly scaly, ugly in color, and the hardness is even less likely to be a relic. Why don't ordinary people have clean and transparent Buddhist relics, but those who have achieved Tao will have Buddhist relics even if they practice for only one year?
There is a book that introduces many stories and anecdotes of monks related to relics from ancient times to the present-"Wonderful Dharma Relic" written by Muqiao lay man.
