Pronunciation: [blˈə͡ʊlamp] (IPA) 
The word "blowlamp" is often spelled with an A instead of an O, as in "blowlamp." However, the correct spelling is actually with an O. The IPA phonetic transcription for this word is /ˈbləʊ.læmp/. The first syllable is pronounced with a short O sound, while the second syllable has an A sound. The word refers to a type of gas torch used for heating or soldering, and is commonly used in industries such as plumbing and welding.
A blow lamp, commonly referred to as a blowtorch, is a portable and hand-held device that generates and directs a concentrated flame for various applications. Typically fueled by gas or other combustible fuels, a blow lamp features a cylindrical body with a handle attached to one end, which houses the fuel supply and control mechanism. At the other end, a nozzle or burner delivers the ignited flame through a fine opening, allowing the user to direct the heat precisely.
Blow lamps are widely employed in a range of activities including soldering, welding, brazing, heating, and even culinary purposes. They are particularly valued in metalworking and plumbing tasks due to their high temperatures and focused flames, capable of generating intense heat suitable for melting or flowing metal alloys. The adjustable flame allows users to control the temperature output, facilitating precise and intricate work.
Blow lamps found in home use often run on butane or propane gas, allowing for easy refill and portability. In industrial settings, blow lamps may be powered by liquefied petroleum gas (LPG), acetylene, or other fuels with higher heat outputs. Safety measures such as flame control valves and protective screens are typically present to ensure safe operation and prevent accidents.
Overall, blow lamps provide a versatile and efficient means of generating high temperatures for a wide range of applications, making them valuable tools in various industries and household settings.
The word "blowlamp" derives from the combination of two separate words: "blow" and "lamp".
The term "blow" comes from the Old English word "blāwan", which means to produce or make a current of air. In this context, it refers to the act of blowing air to fuel or intensify the flame of a lamp.
The word "lamp" has its roots in the Latin word "lampas", which means a torch or a light source. Throughout history, lamps have typically been fueled by oil, gas, or electricity, providing illumination.
By combining "blow" and "lamp", the word "blowlamp" refers to a lamp or a device that is fueled by gas and produces a flame that is intensified or maintained by blowing air or oxygen into it.
