Abstract: A method of preparing gunpowder includes selecting a known combination of chemicals used in making gunpowder; mixing the known combination of chemicals and a measurement of liquid ammonia at a predetermined temperature; stirring the chemicals and liquid ammonia with a laboratory mechanical stirrer, causing the chemicals to blend at a molecular level; raising the temperature of the mixture, causing the liquid ammonia to evaporate from the mixture, while keeping the mixture significantly below ignition temperature; allowing the remaining mixture to warm, thereby reducing the risk of ignition; and resulting in a fine gunpowder mixture, with no water content and limited recrystallization of the chemicals.

Abstract: A microscope slide mounting system includes a slide mounting medium, with a predetermined weight of powdered gum arabic in a predetermined weight of distilled water; a predetermined weight of anhydrous chloral; a predetermined weight of anhydrous glycerin; and a predetermined percentage of ethylene glycol; the ethylene glycol acts as a denaturant in the mounting medium; and the ethylene glycol causes mild illness when ingested, thereby discouraging the use of the mounting medium as a sedative or recreational drug and prevents the crystallization of the medium.
