Close-up of holographic glitter. Glitter is an assortment of flat, small, reflective particles that are precision cut and come in a variety of shapes, sizes, and colors. Glitter particles reflect light at different angles, causing the surface to sparkle or shimmer. Glitter is similar to confetti, sparkles and sequins, but somewhat smaller.
These pigments possess a strong glitter effect. The coating process is analogous to that used for metal oxide mica pigments except it starts from an aqueous suspension of Al 2 O 3 flakes. The complete manufacturing process of pigments based on aluminium oxide platelets, consisting of the flake production and the coating with metal oxides is ...
Iridescence in soap bubbles. Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes.
Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium.
The growth in commercial use of paper towels can be attributed to the migration from folded towels (in public bathrooms, for example) to roll towel dispensers, which reduces the amount of paper towels used by each patron. [12] Within the forest products industry, paper towels are a major part of the "tissue market", second only to toilet paper ...
The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric. The substrate is often flexible and known as a film base . Photographic emulsion is not a true emulsion , but a suspension of solid particles (silver halide) in a fluid (gelatin in solution).
Two photographs of a single hologram taken from different viewpoints. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry.
Adhesive flakes that are mixed with water to produce wallpaper paste. Wallpaper adhesive or wallpaper paste is a specific adhesive, based on modified starch, methylcellulose, or clay [1] which is used to fix wallpaper to walls. [2] Wallpaper pastes have a typical shear thinning viscosity and a high wet adhesive tack.
