Hottest Torch Gas - What Does Borax Do When Melting Gold?

Borax when used in melting of Gold and Silver helps to dissolve Oxides and other impurities and produce a fluid borate slag that collects on the surface of the molten metal. This slag is periodically removed, by use of a carbon-graphite or clay rod.

What gas is best for heating metal?

LPG (liquefied petroleum gas) LPG is recommended for heating thicker weld metals. There is a 4:1 blend ratio of oxygen to LPG, which significantly increases oxygen consumption in addition to noise levels.

What does MAPP gas stand for?

propane	2,820 °C (oxygen), 1,980 °C (air)
propane butane mix	1,970 °C (air)
propylene	2870 °C (oxygen)

What burns hotter butane or MAPP gas?

Mapp gas burns hotter than propane or butane but not as hot as acetylene and can be used on a propane torch interchangeably.

Which is better MAPP gas or propane?

Since MAPP gas burns hotter than propane, it's a good choice for searing. It also delivers a cleaner taste, which appeals to many grillers. On the other hand, MAPP gas is pricier and more difficult to find, and it can be intimidating for amateurs. For everyday grilling, propane is the better choice.

How hot does a blue propane torch get?

Propane Torch Temperature While propane-oxygen combinations can reach a maximum temperature of 3,623 degrees F, or 1,995 degrees C, a propane-butane torch only goes up to 2237 degrees F, 1225 degrees C. A torch flame consists of two cones, an outer light blue flame and an inner dark blue flame.

How hot is bluefire MAPP gas?

BlueFire MAPP gas is used in combination with oxygen for heating, soldering, brazing and even welding due to its high flame temperature of 2925 °C (5300 °F) in oxygen.

Can u braze with MAPP gas?

Mapp gas can be hot enough for brazing if the conditions are right. First, you need to specify mapp/air or mapp/oyxgen. Mapp/air is hot enough to do silver brazing but common brass brazing is a problem because you cannot heat things hot enough quick enough.

Why don't they sell MAPP gas anymore?

It is no longer used much in any large-scale industry – for larger scale users acetylene/oxygen is more economic than MAPP/oxygen when high flame temperatures are needed, and propane/air is more economic when big overall heating is needed.
