The Jewish attitude to the deceased is to show great respect for the dead body. Those who take the responsibility for preparing it for burial are regarded as having special merit. In order that no difference is made between how a rich or a poor person is treated after death, all must have the same kind of white shroud and be buried in the same way. Ideally this is without a coffin, since (in contrast to the Egyptian embalming process) the natural disintegration of the body should not be slowed. Also (in contrast to many heathen religious practices) there is no inclusion of well-loved articles, animals, clothes, foods or treasure of the deceased within the grave.
In Israel, the body is usually laid to rest inside a prepositioned concrete container which replaces the coffin. Flat concrete slabs are used as a cover before the soil is replaced.
However, in some countries, including England, the use of a coffin is mandatory by law, in which case the plainest kinds are preferred for the same reason as described above.
plain rock
plain black and white clothing
A large arctic plain without trees is a tundra.
A white peppermint candy without stripes is a plain cane.
The body is cleansed and the body is wrapped in a white linen or cotton shroud. According to Jewish law, the only acceptable form of burial is to be buried in just a shroud or in a plain wood coffin that has no metal or any finishings that would impede decomposition.
Metal rust quickly in salt water than it does in pure water.
Plain
Neither, its Metalcore, not just plain-old metal
Plain steel is just a Purified and Hard Iron.
The word 'plain' usually means self-evident, without adornment, or a land form. To use these in a sentence: SELF EVIDENT: "It was plain to the police officer that the criminal has been wounded" WITHOUT ADORNMENT: "She had a very plain and ordinary face with no distinguishing characteristics." LAND FORM: "That is a very flat plain."
I could be wrong, but they probably try to chip the stone and stuff off, melt the metal out, or just plain hammer the stuff.
i do believe it does
