This is a hand made wooden crucifix. The wood used is Teak Wood and is varnish finished. The corpus of Jesus is made of Brass metal and is nickel plated to give it a silver tone look. Apart from Churches, this would be perfect for home altars.
A Crucifix: (from Latin cruci fixus meaning "(one) fixed to a cross") is an image of Jesus on the cross, as distinct from a bare cross. The representation of Jesus himself attached to the cross is referred to in English as the corpus (Latin for "body"). (source: https://en.wikipedia.org)
