The armature is made of 10 gauge all purpose steel wire wrapped with chicken wire. The mortar is two parts sand, one part Portland cement, one part lime. Components are mixed dry in a large bucket, then enough water is added to a small portion make it damp and clumpy. I wet my glove, then massage a handful of the mix to the right consistency. I'm experimenting to see if the wire armature is strong enough to support the cement sculpture. The figure is about two feet long.
