what are casts made of
Anyone who has spent time in a cast can relate. Standard casts, made of fiberglass or plaster, are not very wearer-friendly. They can degrade when exposed to moisture, forcing people with casts to get creative with keeping them dry in a shower. Evill designed a new type of cast with these limitations in mind.
For the use of plaster casts in medicine, see Orthopedic cast. Plaster cast bust of George Washington by Jean-Antoine Houdon based on a life mask cast in 1786. A plaster cast is a copy made in plaster of another 3-dimensional form.
