How is shellac knotting made?

Shellac knotting is made by dissolving shellac flakes in a solvent, typically ethanol, to create a viscous liquid. The mixture is then applied to knots or blemishes in wood to seal and protect them while enhancing the wood's appearance. Once applied, it dries quickly, forming a hard, durable finish that can be sanded or polished. This technique is commonly used in furniture finishing and woodworking to achieve a smooth, professional look.
