This tree is created with wire gages ranging from 32 to 18. The wire used is bronze anodized aluminum wire which will retain its color and strength for many years. This is the same wire that we use for training bonsai. The tree sculpture is bonded onto its base, which is a glazed ceramic bonsai pot, using sea sand. Since the bond is made onto a porous material, a water soluble glue is used and, therefore, clean your tree sculpture with a damp, soft, lint-free cloth
