Fire glass (also fire pit glass, fire rocks, fire beads or lava glass) is a type of tempered glass, chunks of which are used decoratively on fireplaces. Pieces of the glass are heaped around jets of burning gas, or around liquid ethanol , in order to conceal the jets and reflect the flames. [ 1 ]
[2] [3] Dispatchers at a central facility used a compass rose to mark lines of position from each reporting tower onto a large map to quickly find where the reported bearings intersect. Today, a more precise determination of a fire location can be made by the use of a single Fire Finder in conjunction with a digital elevation model (DEM). [4]
Flammagenitus cloud above the 2014 Oregon Gulch Fire in Oregon and California, 2014. Aircraft is an F-15C Eagle. Flammagenitus is often grayish to brown in color because of the ash and smoke associated with the fire. It also tends to expand because the ash involved in the cloud's formation increases the amount of condensation nuclei.
This occurs when the fire burns with a low flame and spreads slowly. [9] Typical appearance of a creeping fire. Typical appearance of a creeping fire. Many Smoldering: Smoldering is when a fire burns without much flame but with large amounts of smoke. It typically occurs after the flaming combustion phase.

ASTM D5773, Standard Test Method of Cloud Point of Petroleum Products (Constant Cooling Rate Method) is an alternative to the manual test procedure. It uses automatic apparatus and has been found to be equivalent to test method D2500. [4] The D5773 test method determines the cloud point in a shorter period of time than manual method D2500.
The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...
In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
