Methods of making, and the resultant monolithic drum shell for a musical instrument, that include selecting one or more desired wood fibers, providing a resinous binder solution, and immersing the wood fibers within the resinous binder solution for a duration that saturates and covers the wood fibers with the resinous binder solution to form a drum shell liquid composition. The drum shell liquid composition is deposited into a mold, and then cured to form a monolithic composite drum shell. The monolithic composite drum shell is removed from the mold to provide a ready-to-use drum shell for assembling into a musical instrument.

The present application relates to the field of black coloring of materials made from wood, such as reconstituted wood panels or paper/cardboard. The black coloring composition for wood-based materials includes a black pigment, a reactive type black dye and water. It is also possible to prepare a dry extract for some special applications.

A novel pigment and a method to create the novel pigment are described. A raw material, such as municipal sewage sludge, municipal compost, food waste, agricultural waste, forestry waste, agroforestry waste, biomass, and/or livestock waste, are screened, cleaned, and/or prepared. The raw material is digested by microorganisms to create methane and a biosolid. The biosolid is dried and then carbonized to create a biochar. The biochar is ground into a powder pigment until a predetermined particle size is reached. The powder pigment having the predetermined particle size is applied to a media to create at least one product, such as an ink, a paint, a stain, a colored material, and/or a dye.

The present invention relates to the creation of thermally insulating materials derived from cellulosic materials by selectively depolymerizing the materials anatomy. Cellulosic materials may be comprised of three main biopolymers: lignin, hemicellulose, and cellulose. The present invention relates to the chemical and physical removal of lignin and hemicellulose, while leaving the cellulose unaltered to induce increased porosity within the material and the material's macrostructure matrix for use as thermal and acoustic insulation. The increased porosity will be due to the creation of closed cell voids within the cellulosic matrix. These voids will increase the thermal and acoustic insulating performance of the cellulosic materials. The selective removal of secondary biopolymers from cellulosic materials allow for isolation of other value added products that can be regenerated through fewer reactions/steps. This is a novel advantage over other similar processes that dissolve cellulose completely, making it harder to extract and isolate secondary off-stream products.

A composition for a wood restorer with a stain, the composition comprising: a polymer emulsion, wherein the polymer emulsion comprises a styrene acrylic copolymer emulsion and a high density polyethylene emulsion, a stain, and a first water, wherein the first water forms the balance of the composition. A method of using the composition to cleanse a wood surface is also disclosed.

A delignified wood material is formed by removing substantially all of the lignin from natural wood. The resulting delignified wood retains cellulose-based lumina of the natural wood, with nanofibers of the cellulose microfibrils being substantially aligned along a common direction. The unique microstructure and composition of the delignified wood can provide advantageous thermal insulation and mechanical properties, among other advantages described herein. The thermal and mechanical properties of the delignified wood material can be tailored by pressing or densifying the delignified wood, with increased densification yielding improved strength and thermal conductivity. The chemical composition of the delignified wood also offers unique optical properties that enable passive cooling under solar illumination.

The invention relates to methods to thermally treat wood (e.g., flat-grain timber) to produce wood with enhanced color and/or weathering properties.
