“Glaze” is a special coating technology that originated from the “Western Expansion Movement” in the United States in the 18th and 19th centuries. Furniture at that time was easily damaged when traveling by carriage and was made of thick “water-based”. Bottom coat + top stain coat to hide visible imperfections in the wood. Glazes are now widely used on wooden floors to achieve harmonious tones and a clear gray/light surface.
