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.

The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
Commercial gelatin will have a gel strength of around 90 to 300 grams Bloom using the Bloom test of gel strength. [6] Gelatin's strength (but not viscosity) declines if it is subjected to temperatures above 100 °C (212 °F), or if it is held at temperatures near 100 °C for an extended period of time. [7] [8]
However, one gram of hydrogen reacts with 8 grams of oxygen to give water or with 35.5 grams of chlorine to give hydrogen chloride: hence 8 grams of oxygen and 35.5 grams of chlorine can be taken to be equivalent to one gram of hydrogen for the measurement of equivalent weights. This system can be extended further through different acids and bases.
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
The most commonly used formula is an FBI-style 10% ballistic gelatin, which is prepared by dissolving one part 250 bloom type A gelatin into nine parts of warm water (by mass), mixing the water while pouring in the powdered gelatin. It is chilled to 4 °C (39 °F).
Grass jelly, also known as leaf jelly or herb jelly, is a jelly-like dessert originating in China. It is commonly consumed in East Asia and Southeast Asia . It is created by using Chinese mesona (a member of the mint family ) and has a mild, slightly bitter taste.
It is defined by the force in grams required to press a 12.5 mm (0.49 in) diameter plunger 4 mm (0.16 in) into 112 g (4.0 oz) of a standard 6.67% w/v gelatin gel at 10 °C (50 °F). The bloom strength of a gel is useful to know when determining the possibility of substituting a gelatin of one bloom strength for a gelatin of another.
