Some pictures of relic flowers and relics seen on the Internet are obviously unburned bones, some of which are very hard, some are crystal clear and colorful. Some people say it's mysterious and that modern science can't explain it. Let me make it clear first: as long as there are enough samples, it is a piece of cake to analyze its composition and structure by modern scientific means, and then it is not difficult to infer its formation mechanism. Invisible coatings on airplanes are high-tech, right? The wreckage of a long-distance raid on Osama bin Laden's plane was brought to China, and it can be found out three times and five times, but China may not value it, because the stealth focus of the helicopter is on noise reduction, rather than stealth paint to avoid radar.
This paper attempts to explain the formation mechanism of this relic from a scientific point of view.
1, the fuel for monks' cremation is wood, and the flame temperature is far from the standard of modern cremation facilities. It is normal that some bones are not burnt out, which is called residual flowers;
Generally speaking, most people will have a good idea before the end of their lives. Monks should be smart people and know this better, so they consciously swallowed some minerals before they died, the most important of which was the flux to reduce the melting temperature, followed by non-ferrous metal oxides. Due to the long cremation time and high local temperature, the original (such as stones) and deliberately swallowed minerals in the body are melted and recrystallized to form relics;
3. It is not excluded that some Buddhist relics are simply jade beads swallowed before their death. Because there is no X-ray film of the monk before his death, it is impossible to draw a clear conclusion. Similarly, no one can definitely deny my point of view.
The monk's heart is still soft after cremation, and gradually hardens after cooling. How to explain it? It doesn't bother me. When I was a child, I liked burning mud. I burned the yellow mud and the mud rich in organic matter. It was soft when it was first taken out, but it hardened after cooling. Why think of yourself? By the way, an unburned heart dominated by organic matter is more likely to change from soft to hard.
The firing temperature of ceramics is generally divided into three grades: low-temperature ceramics (below 700℃), medium-temperature ceramics (700- 1200℃) and high-temperature ceramics (above 1200℃). The cremation temperature of monks easily exceeds 700℃, and the cremation time is long. As long as you consciously swallow some minerals, the remains will definitely appear. To burn exquisite relics, such as high hardness and beautiful colors, depends on the level of knowledge mastered by monks, such as flux can lower the melting point, what substance can be used as flux, and what color metal elements present. Some people know much, while others know little.
It's not that modern science can't analyze the composition and causes of sarira, but it's based on respect for religion and believers, and there's no need to pierce enough. In other words, it is necessary and unnecessary to do it. I don't mean to profane any religion, but it's too much to say nothing. Then "universal values" don't like others to say a few words of questioning, which is not good!
