Pronunciation: [blˈast lˈamp] (IPA) 
The correct spelling of "blast lamp" is /blæst læmp/. The word "blast" is pronounced with a short "a" sound followed by a voiceless "s" and a voiceless "t". The vowel sound in "lamp" is a lax "a" sound followed by a voiced "m" and a voiceless "p". Together, the two words describe a lamp that is used for blasting or welding purposes. It generates a concentrated beam of light to aid in the process of metalworking.
A blast lamp is a portable lighting device that utilizes a jet of air or oxygen to intensify the combustion of fuel, thereby generating a bright and focused light source. Also known as a blowtorch or blow lamp, a blast lamp typically consists of a fuel container, a fuel valve, an air or oxygen valve, a burner assembly, and a nozzle.
The fuel container is designed to hold a combustible liquid fuel, such as kerosene or gasoline, that is mixed with air or oxygen. The fuel valve controls the flow of fuel from the container to the burner assembly, while the air or oxygen valve regulates the supply of air or oxygen required for combustion.
The burner assembly includes a wick or a burner head that is connected to the fuel and air/oxygen supply. The nozzle, located at the front of the burner assembly, directs and shapes the resulting flame into a focused beam of light. The intensity of the flame and the light can usually be adjusted using the fuel and air/oxygen valves.
Blast lamps are commonly used in various applications such as outdoor lighting, construction sites, camping, and welding. They are valued for their high-intensity light output, portability, and versatility. However, it is important to handle blast lamps with caution due to the risks associated with fuel combustion and the hot flame generated by the device.
The word "blast lamp" is a compound word made up of two individual words: "blast" and "lamp".
The word "blast" can be traced back to the Old English word "blæst", which means a gust of wind or an explosion. This word also has Germanic origins.
The word "lamp" comes from the Middle English word "lampe", which was borrowed from the Old French word "lampe". The Old French word originated from the Latin word "lampas" and the Greek word "lampas", both of which mean a torch or lamp.
Therefore, the etymology of "blast lamp" is a combination of the Old English word for a gust of wind or explosion and the Middle English borrowing of the Latin and Greek words for a torch or lamp.
