Because Acid is too destructive that can destroy everything,even the stone,lava and cloner.
Glass is a kind of fire-resistant solid material that will not be corroded by acid. It can be destroyed by falling stone and will become new lava with the high temperature of magma. In addition, it has good thermal conductivity and a smooth surface .
Please add "Glass".
