Extending the life of wooden furniture indoors

Wooden furniture will remain beautiful for years with simple maintenance. Protect it from moisture, sunlight, dust, heat, and everyday scratches. Maintain indoor humidity, keep furniture away from damp areas, and clean it regularly with a soft cloth. Protective finishes like wax, varnish, or oil help prevent damage. Boiled linseed oil is particularly effective because it nourishes the wood and dries quickly. With regular cleaning, inspection, and a good finish, your wooden furniture will remain strong, shiny, and long-lasting.

Why Ethanol Cannot Be Distilled Above 96%

Why Ethanol Cannot Be Distilled Above 96%

Ethanol cannot be distilled above 95-96% ethanol because it forms an azeotrope with water. At this point, the liquid and vapor have the same composition, making distillation impossible to separate. Even with higher heat, the purity will not increase. Industries requiring near-100% ethanol use additional drying methods such as molecular sieves, special distillation with added chemicals, or vacuum distillation. These techniques break the azeotrope and produce anhydrous ethanol for chemical, industrial, and laboratory use.

The role of isopropyl alcohol in industrial cleaning processes

The role of isopropyl alcohol in industrial cleaning processes

Isopropyl alcohol (IPA) is widely used in industry because it cleans quickly, evaporates quickly, and leaves no residue. It dissolves oil, dirt, adhesives, and flux, making it ideal for electronics, metalworking, laboratories, and manufacturing. IPA is safe for most plastics and metals and helps prevent corrosion or short circuits in electronic components. It is also used as a surface cleaner before coating or painting. While effective, IPA is intended for technical use only and should never be consumed.

Denatured alcohol – what is it and why is it used?

Denatured alcohol – what is it and why is it used?

Denatured alcohol is regular ethanol that producers intentionally make undrinkable by adding substances such as isopropanol (IPA), methyl ethyl ketone (MEK), Bitrex, or methanol. These additives make the alcohol bitter, unpleasant, or toxic, so no one can drink it and no excise duty has to be paid. This keeps ethanol affordable and available for technical applications, such as cleaning, degreasing, cleaning electronics, as a solvent in laboratories and industry, and as a fuel for methylated spirits.
Chemically the effect remains the same, but due to denaturing the alcohol falls outside the liquor laws.
This article explains how and why ethanol is denatured, which substances are used for this process, and what you can safely use this alcohol for—from household use to professional laboratory work.
