The Bagua convex mirror has the function of blocking evil spirits in Feng Shui. I would like to ask all the masters, which is better, the copper mirror or the glass mercury mirror?

From the perspective of Feng Shui, the effect of bronze mirrors is better.

Because copper itself has a certain effect of reducing evil spirits and suppressing houses. Combined with a mirror, the effect is even better. Especially now that the polishing technology is higher, the surface of the bronze mirror can be polished smoother and clearer, and the effect is better than in ancient times.

Although the mercury mirror also has a reflective effect, its effect of suppressing the house and dispelling evil spirits is weak, so the effect is not as good as that of the bronze mirror.

However, if it is just from the perspective of reflecting evil spirits, both can be used, and the effect is not much different. It’s just that bronze mirrors have more additional effects, so I say that bronze mirrors are more effective. For reference.
