What Is a Blow Torch?
A blow torch is a handheld tool that creates a focused high-temperature flame using fuel gas such as butane or propane.
Unlike ordinary lighters or open flames, a blow torch gives users precise control over flame size, intensity, and direction.
This makes blow torches ideal for:
- Steak searing
- Crème brûlée caramelization
- BBQ charcoal ignition
- Outdoor cooking
- DIY heating projects
- Small repairs and soldering
Modern culinary torches are designed to be portable, refillable, and beginner-friendly.
How Does a Blow Torch Work?
A blow torch works by mixing fuel gas with oxygen and igniting it through a nozzle system.
Most culinary torches use butane gas because it burns cleanly and provides stable flame control.
Main Components
- Fuel tank
- Ignition system
- Flame nozzle
- Flame adjustment valve
- Safety lock
When the ignition button is pressed, gas flows through the nozzle and ignites instantly, creating a concentrated flame.
