Re: Rust on the stem
The chinese was made out of Aluminum most likely while this one is steel. This is somewhat typical of the handmade pipes, the places that weren't plated. On mine it usually happens on the bottom of the flanged end of the downstem on my kms or up in the chiller. Since its just surface rust get some fine grit sandpaper and sand it off and towel dry the stem after cleaning. Another thing is don't store the stem inside the vase right away, if its not dry humidy inside will make it rust.
