There are five different forms of gas canister available which contain a range of gases.

Butane gas canister

Butane gas cartridge for a blow lamp Butane is an alkane, which is a type of gas made from hydrogen and carbon. It produces the lowest temperatures of all of the gas canisters, with a maximum of 1350°C (2462°F). These canisters can be used in air temperatures as low as -3°C (26°F).

Butane gas canisters can be used for soft soldering and are available for standard and swivel blow lamps.

Wonkee Donkee says "If the air temperature falls below a certain point, then the gas loses its ability to turn into a gas from its liquefied state in the gas canister. Therefore the blow lamp will cease to work"

Propane gas canister

Propane gas cylinder for a blow torch Propane is an alkane, similar to butane. However, it has fewer carbon atoms than butane. It produces a hotter flame, up to 1900°C (3452°F), than butane propane mixed gas canisters (see below), which means it is a better gas source for brazing and soldering large-diameter pipes.

It can be used at temperatures as low as -20°C (-4°F).

Heavy duty blow lamp A propane gas canister can be used by all the varieties of blow lamp and comes in either 340g (12oz) or 400g (14.1oz) sizes.

Butane propane mixed gas canister

Butane propane mixed gas cartridge for a blow lamp Butane propane mixed gas canisters are the most common variety available. They contain a 35% propane and a 65% butane combination which creates more heat than a purely butane canister, with a flame temperature up to 1750°C (3182°F).

Butane propane mixed gas canisters can come in sizes ranging from 170g (6oz) to 350g (12.3oz).

Cold temperatures, polar bear in the snow It can be used by all four varieties of blow lamp at temperatures as low as -15°C (5°F).

Mixed gas canister

Mixed gas cartridge containing propane, butane, propene and acetone for a blow lamp Mixed gas canisters contain a combination of propane, butane, propene and acetone. This combination of gases creates a very hot flame of up to 2100°C (3812°F) which is ideal for brazing.

It can only be used by heavy duty blow lamps and is only available in one size: 210g (7.4oz).

Skiing in the snow, cold temperatures Mixed gas can be used at temperatures as low as -18°C (-0.4°F).

Propane and methyl acetylene propadiene gas canister

Propane and methyl acetylene propadiene gas cannister for a blow lamp Propane and methyl acetylene propadiene gas canisters are the hottest commercially available gas canister and produce a flame of up to 2200°C (3992°F).

They can come in sizes ranging from 400g (14oz) to 450g (15.9oz).

Celsius Fahrenheit Temperature They are used for brazing, welding, and cutting metals. They are only available for use with a heavy duty blow lamp and can be used at temperatures as low as -20°C (-4°F).
