On the first picture below I am pretty sure the grip is made of plastic because it feels very light, when I lift it. On the second I have no idea. Question How do I tell if the grip of a faucet is made of plastic or metal? Are there destructive and non-destructive tests I can do?

In the strictest sense, if it has a metallic finish, it is metal, though it may only be a few molecules thick over a plastic substrate. But you refer to the base material. It can be hard to tell when it's in place due to the resistance of the mechanism masking the apparent mass. The way to distinguish without destructive sampling is essentially it's mass. Metal is denser than plastic. Removing the handle will usually make it easy to to tell just by weight. Many modern faucets are often made of both metal and plastic parts though. One can still be fooled by weight. A solid, quality plastic handle may weigh more than a hollow, thin, cheap brass handle. The only sure way is to take a sample by drilling a small hole in an inconspicuous place. The shavings could be tested in a lab, after which they could determine exactly the type of resin or metal composition, if you paid them enough. It usually suffices to simply hold a flame to the shavings. Plastic burns, metal does not. |
