Bloom is a test used to measure the strength of a gel, most commonly gelatin.The test was originally developed and patented in 1925 by Oscar T. Bloom. [1] The test determines the weight in grams needed by a specified plunger (normally with a diameter of 0.5 inch) to depress the surface of the gel by 4 mm without breaking it at a specified temperature.

Gelatin is nearly tasteless and odorless with a colorless or slightly yellow appearance. [3] [4] It is transparent and brittle, and it can come as sheets, flakes, or as a powder. [3] Polar solvents like hot water, glycerol, and acetic acid can dissolve gelatin, but it is insoluble in organic solvents like alcohol. [3]
Potato starch slurry Roux. A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.
If a free-flowing powder is mixed with a cohesive powder an interactive mixture can be obtained. The cohesive particles adhere to the free-flowing particles (now called carrier particles) to form interactive units as shown in figure B. [ 3 ] An interactive mixture may not contain free aggregates of the cohesive powder, which means that all ...
Ballistic gelatin is traditionally a solution of gelatin powder in water. Ballistic gelatin closely simulates the density and viscosity of human and animal muscle tissue, and is used as a standardized medium for testing the terminal performance of firearms ammunition. While ballistic gelatin does not model the tensile strength of muscles or the ...
Gelatin capsules, informally called gel caps or gelcaps, are composed of gelatin manufactured from the collagen of animal skin or bone. [4] Vegetable capsules, introduced in 1989, [5] are made from cellulose, a structural component in plants. The main ingredient of vegetarian capsules is hydroxypropyl methyl cellulose. In the 21st century ...
Gelignite (/ ˈ dʒ ɛ l ɪ ɡ n aɪ t /), also known as blasting gelatin or simply "jelly", is an explosive material consisting of collodion-cotton (a type of nitrocellulose or guncotton) dissolved in either nitroglycerine or nitroglycol and mixed with wood pulp and saltpetre (sodium nitrate or potassium nitrate).
The Carr index (Carr's index [1] or Carr's Compressibility Index [2]) is an indicator of the compressibility of a powder.It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula =, where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after "tapping down".
