Yes, the Chinese are credited with inventing lacquer. The use of lacquer dates back to at least the Shang Dynasty (c. 1600–1046 BC) in China. Lacquer is a type of varnish made from the sap of the lacquer tree and has been used for decorative and protective purposes on various objects.
When lacquer gets wet, it can soften and become tacky, losing its smooth and hard finish. Over time, prolonged exposure to moisture can cause the lacquer to break down, leading to peeling, cracking, or cloudiness. It is important to keep lacquer-coated surfaces dry to maintain their quality and appearance.
To remove lacquer from a stone floor, you can use a lacquer thinner or solvent following the manufacturer's instructions. Apply the solution to the affected area, let it sit for a few minutes, and then scrub the floor with a brush or scrubbing pad. Once the lacquer has softened, wipe it away with a clean cloth and rinse the area with water.
The density of lacquer thinner typically ranges from 0.75 to 0.85 grams per milliliter, depending on the specific formulation.
Common solvents that can dissolve lacquer include acetone, ethanol, and lacquer thinner. It is important to always test a small inconspicuous area first and follow proper safety precautions when working with these solvents.
Naphtha is commonly used as a solvent to slow down the drying time of lacquer. Using a solvent like naphtha can help to adjust the drying speed of lacquer to achieve the desired finish. It is important to follow safety precautions and manufacturer's recommendations when working with solvents.

The exact number of Chinese lacquer trees (Toxicodendron vernicifluum) in China is not precisely documented, as they are cultivated in various regions for their sap, which is used to produce lacquer. These trees are primarily found in provinces like Guangdong, Guangxi, and Jiangxi. While they are not considered endangered, their population can fluctuate based on cultivation practices and environmental factors. Overall, they are an important part of traditional Chinese craftsmanship and culture.
