Gypsum itself is not phosphorescent; it is a mineral composed of calcium sulfate dihydrate. Phosphorescence refers to the property of certain materials to absorb light and then re-emit it over time, which is not a characteristic of gypsum. However, some gypsum crystals may exhibit fluorescence under specific lighting conditions, but this is different from phosphorescence.
First of all, Gypsum is a mineral, and Rock Gypsum is a rock, don't get them confused. Second of all, no they aren't. Rock Gypsum is a sedimentary rock, and an alternate name for it is Alabaster.
The Harmonized System (HS) code for gypsum is 2520.
The systematic name for gypsum is calcium sulfate dihydrate.
Gypsum is calcium sulfate - CaSO4.

Bioluminescence is the production of light by living organisms, while phosphorescence is the emission of light by a substance after it has absorbed energy.
Phosphorescence is similar to fluorescence in that both involve emission of light by materials after they have absorbed energy. The main difference is the time scale: fluorescence is immediate, while phosphorescence has a delay before light is emitted.

Phosphorescence and fluorescence are both types of light emission, but they differ in how long they last. Fluorescence is a quick emission of light that stops as soon as the light source is removed, while phosphorescence continues to emit light for a period of time after the light source is removed.
Fluorescence and phosphorescence are both processes where a substance absorbs and then emits light. The key difference is in the timing of the light emission. Fluorescence happens almost immediately after the substance absorbs light, while phosphorescence involves a delay in the emission of light, which can last from milliseconds to hours.
No, gypsum is not metallic.

Phosphorescence can be useful in mining eucryptite because it can help identify the presence of this mineral in the ore. Eucryptite typically exhibits phosphorescence under ultraviolet light, making it easier to distinguish from other minerals. This property can aid miners in locating and extracting eucryptite from the surrounding material.
