The weight of ashes is only about three to five kilograms, which is about the weight of six or seven books. The family members of the deceased are emotionally unstable and can't accept that their relatives have changed from the original appearance to only three kilograms of ashes, so they will say that the funeral home only allows family members to take away half of the ashes.

First of all, the funeral home is strictly managed by the state, and the staff inside are all state officials, all of whom have their own professional ethics and act in strict accordance with state regulations.

Secondly, for people in funeral parlours, the ashes burned after death are of no use to them, and no one will withhold the ashes, which is disrespectful to the deceased and their families and will be condemned by society and morality.

It is human nature to be born and die. Before liberation, most people chose burial. Now cremation is the most common choice. After being cremated, the deceased will eventually become a pile of ashes.

According to the bulletin of national physique monitoring in 2000, the weight of adult males in China tends to be stable after the age of 35, reaching the maximum at the age of 40-69, with an average of 67.7 kg; Adult women's weight tends to be stable after 40 years old, reaching the maximum at 50-54 years old, which is 59.6 kg. So after cremation, the weight of ashes is the weight multiplied by 3.5%.

Burning in a cremator at a temperature of 760~ 1 150 degrees for two hours, most of the human body (especially organs) and other soft tissues will be vaporized and oxidized by the heat and gas released by the exhaust system. What remains after cremation is dry bone fragments (mostly calcium phosphate and secondary minerals). Because the weight of dry bone fragments is very close to that of bones, it will vary from person to person. A study pointed out that the weight of adult ashes ranged from 0.9 to 3.6 kg, with an average weight of about 2.4 kg, that of boys was 2.7 kg, and that of women was 1.8 kg. After cremation, the remains were all dry bone fragments, which was equivalent to about 3.5% of the original weight.
