What is aquamation?

This is what happens when Gramps falls off his garbage-scow. With aquamation, or “alkaline hydrolysis”, the body of the deceased is immersed for three to four hours in a mixture of water and a strong alkali, such as potassium hydroxide, in a pressurised metal cylinder and heated to around 150C. The process liquifies everything except for the bones, which are then dried in an oven and reduced to white dust, placed in an urn and handed to Qanon relatives.
