Itacolumite is a naturally occurring porous, a sandstone that is flexible when cut into thin strips. The chemical corrosion appears to be the main reason for the formation of more void spaces in between the constituent grains in the flexible sandstones. sandstone formed from the decomposition of gneisses which contained feldspar grains.This sediment accumulated together just like any old sandstone, but the feldspar grains continued to decompose. This would have left lots of empty spaces within the rock leaving it a lump of loosely interlocking grains of quartz.
