Product instruction 

Metal tableware is usually made by stainless steel ,it easy to forming and polishing . titanium is better to people's health and the density is smaller ,but the material and production cost are more expensive than stainless  steel .

The difficulty of spinning 

the ductility of titanium is bad and the tensile strength is big ,so it is harder to spin in the absence of heat , the polishing performance is bad as the poor thermal conductivity ,it is easy to burnout because heat can't release .
