Similarly to bone, antler may be used in its natural form, polished with abrasives for a glossy surface, and treated with a burning process for a charred finish and color. Antler has been used for numerous objects throughout history including tools such as hammer batons, knife handles, pressure flakers, and conical arrow points.
A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .
Various nitrogen compounds were made from hartshorn shavings: . Oil of hartshorn is a crude chemical product obtained from the destructive distillation of deer antlers.; Salt of hartshorn refers to ammonium carbonate, an early form of smelling salts and baking powder obtained by dry distillation of oil of hartshorn.
Wood stain is a type of paint used to colour wood comprising colourants dissolved and/or suspended in a vehicle or solvent. Pigments and/or dyes are largely used as colourants in most stains. The initial application of any paint or varnish is absorbed into the substrate similarly to stains, but the binder from a stain resides mainly below the ...
An antler on a red deer stag. Velvet covers a growing antler, providing blood flow that supplies oxygen and nutrients. Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone. [6]
Wood chemistry, whose primary focus is the analysis of the chemical constituents comprising wood, with specific emphasis on cellulose, lignin, hemicelluloses, and extractives, as well as on the various products derived from these components. It is also explores potential uses for pulp and paper production, the utilization of wood and wood waste ...
An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.

The material that is trapped coats the underlying material, and the stain reflects backlight according to its own color. Applied paint, spilled food, and wood stains are of this nature. [5] A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types of natural stains fall into ...
