What is Shellac?

Shellac is a natural resin obtained from the secretions of the lac beetle (Kerria lacca), which is primarily found in Southeast Asia. The resin is harvested from the trees where these beetles reside, and it undergoes a series of processes to produce the shellac flakes that are commonly used in various applications. These flakes can be dissolved in alcohol to create a liquid form, which can then be applied as a finish or coating.

Shellac is known for its warm amber color, high gloss finish, and excellent adhesion properties, making it a popular choice among woodworkers and artisans. It is also biodegradable and non-toxic, making it an environmentally friendly option compared to synthetic resins and finishes.
