The thickness (concentration) of shellac is measured by the unit "pound cut", referring to the amount (in pounds) of shellac flakes dissolved in a gallon of denatured alcohol. For example: a 1-lb. cut of shellac is the strength obtained by dissolving one pound of shellac flakes in a gallon of alcohol (equivalent to 120 grams per litre). [14]
Rubbing alcohol, also known as surgical spirit in some regions, refers to a group of denatured alcohols commonly used as topical antiseptics. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol , with isopropyl alcohol being the more widely available formulation.
The addition of methanol, which is poisonous, renders denatured alcohol unfit for consumption, as ingesting denatured alcohol may result in serious injury or death. [2] Thus denatured alcohol is not subject to the taxes usually levied on the production and sale of alcoholic beverages. Aniline was used to denature colza oil in the 1980s. [3]
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Neutral spirit is legally defined as spirit distilled from any material distilled at or above 95% ABV (190 US proof) and bottled at or above 40% ABV. [5] When the term is used in an informal context rather than as a term of U.S. law, any distilled spirit of high alcohol purity (e.g., 170 proof or higher) that does not contain added flavoring may be referred to as neutral alcohol.

Absinthe (/ ˈ æ b s ɪ n θ,-s æ̃ θ /, French: ⓘ) is an anise-flavored spirit derived from several plants, including the flowers and leaves of Artemisia absinthium ("grand wormwood"), together with green anise, sweet fennel, and other medicinal and culinary herbs. [1]
Green liquor is the dissolved smelt of sodium carbonate, sodium sulfide and other compounds from the recovery boiler in the kraft process. The liquor's eponymous green colour arises from the presence of colloidal iron sulfide. [1] The green liquor is usually reacted with lime (CaO) in the causticizing stage to regenerate white liquor ...
A quick estimate of the alcoholic strength, or proof, of the distillate (the ratio of alcohol to water) is often achieved by shaking a clear container of the distillate. Large bubbles with a short duration indicate a higher alcohol content, while smaller bubbles that disappear more slowly indicate lower alcohol content. [citation needed]
