What are some jewish funeral customs?

Funerals should take place as soon as possible, often done on the day of death or the following day. Autopsies are not routinely done unless required by law. Cremation isn’t allowed because traditional Jews are prohibited to desecrate a body by artificial means. Burial is a plain wooden casket with no metal, which includes no metal handles or nails. They are put together with wooden
pegs. Actually, Jewish tradition is to bury the person without a coffin. If a coffin is mandatory by law tradition dictates
choosing a simple one. The body is clothed in a white linen shroud, not street
clothes. Shrouds are sewn without knots, and are a multiple piece
garment. Today, virtually all (Jewish)
mortuaries carry shrouds, the prices vary.
