Precisionshaped concave bowl bottom: The tamping tank has a curved, concave bottom made from grade copper. Its shape matches the hammer of the tamping rod to deliver consistent, even compression and more efficient grinding or pounding. Onepiece seamless construction: The bowl and tamping rod are integrally formed into a single solid unit. This solid, seamless design prevents gaps that trap residue, makes cleaning fast and simple, and avoids powdering or chipping during use. Smooth solid copper interior and exterior: Finished inside and out in grade copper, the surface is smooth for easy release of ingredients and straightforward cleaning. Copper construction is durable, visually attractive, and contributes trace elements naturally found in food contact use. Stable solid flat base: The base is cast from solid brass and finished flat and seamless. A widened footprint gives the unit stable, wobble performance on work surfaces during heavy tamping or grinding. How this solves common problems Eliminates uneven tamping or grinding by matching bowl shape to the tamping hammer for uniform force distribution. Reduces cleanup time and contamination risk thanks to an integral, seamless design that leaves no crevices for material to collect. Prevents tipping and slipping with a heavy, flat brass base that stays firmly in place under pressure. Materials and performance Bowl and tamping rod: grade solid copper, smooth finish inside and out. Base: solid brass casting, flat and widened for stability. Performance: durable, easytoclean, designed for repeated use without loosening or producing powder residue. Typical applications Grinding spices and herbs to a fine, consistent texture for cooking. Preparing pastes and condiments such as garlicginger paste, pesto, or herb blends. Crushing or pulverizing medicinal herbs or supplements for traditional preparations. Care and compatibility notes Clean after each use to maintain the smooth copper finish; copper will develop natural patina over time. Designed for manual tamping/hammering applications where a matched concave bowl and hammer/pestle improve efficiency and consistency. What sets it apart Integrated solid construction and matched concave design for reliable, uniform tamping. grade copper finish that is both functional and attractive. Heavy brass base for stable, safe operation during heavyduty use.
