Finish Recommendations
High-quality oils (Tung/Linseed) or shellac to pop the figure, followed by wax or lacquer for protection. Void filling with black or clear epoxy is recommended for this specific burl sample.
Notable Features
Distinctive 'nutty' scent when worked. Contains juglone, which can cause mild allergic reactions in some individuals. Known for exceptional acoustic properties and aesthetic depth.
