Excerpts from related articles are as follows:

Tung trees are deciduous trees, such as white paulownia, catalpa bungeana and paulownia. Its material is light, soft, elastic and fine-grained, and it is not easy to be corroded by insects, and it is not easy to burn because of heat insulation and moisture resistance. Tung oil tree is the best, and its trunk can only grow to 10m in 20 years. It is a precious broad-leaved timber tree with strong material and corrosion resistance. If the paulownia wood is very old, its wood liquid is completely lost, the wood color is all white, purple and transparent, the texture is delicate, and it is the best material for piano. Paulownia wood is very rare now, and it is hard to find. (Note: At present, the price of the old paulownia guqin panel on the market is about 8000 yuan).

This thing is for guqin. Never heard of a furniture maker.

I agree with 1 Lou. Nine times out of ten, it's dyed technical wood, and I made up a name myself.
