The Mother Tesla Gong is an unlathed gong.
This is how a gong looks when it comes out of the oven. Most Chinese Gongs have this color when they come out of their cast mold, but then are lathed to create different tones.
The Mother Tesla Gong maintains a deeper tone. It doesn’t crash like a Wind Gong, or even a Chau.
The Mother Tesla Gongs are great for engraving on, as the image engraved really shows up well.
