What liquid is used in a forge?

By soaking the pieces in Kerosene before heating, you coat the surfaces in the oily liquid. When the steel is put into the forge, the Kerosene burns off, leaving a layer of carbon coating the surface, which inhibits oxidisation. The advantages is that Kerosene can get into cracks and doesn't harm the forge lining.

What is the liquid used in forging?

Blacksmiths generally use water, oil, or compressed air to quench. These substances vary in environmental impact, cost, and effects on the metal, but the best quenching medium is usually water or quenching oil.

What quench oil is used on forged in fire?

These are fast and medium speed oils, and the most widely used products on the market are Parks 50 (fast) and AAA (medium). The best oil to use depends on the steel in question. There are however some smiths who use one type for all steels.

What fuel is used in a forge?

A forge typically uses bituminous coal, industrial coke or charcoal as the fuel to heat metal. The designs of these forges have varied over time, but whether the fuel is coal, coke or charcoal the basic design has remained the same.

What liquid is used for quenching?

Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking. When hardness can be sacrificed, mineral oils are often used.

What liquid is best for quenching steel?

Mineral oil quenchants are excellent for oil-hardened steels and steels that require a fast quench rate. They tend to be on the expensive side, but they're highly efficient and have greater cooling capacities for steel alloys.

What did medieval blacksmiths quench their blades in?

The smith then heats the metal so that both the iron and steel are molten and join. The blade is tempered—transformed from soft, workable metal into a hard blade—by holding the blade over a fire and then quenching the blade in a vat of oil or brine.

What is the best fuel for a forge?

Coal and propane are the most typical fuels used in blacksmith forges. On the East Coast, coal is readily available and therefore more affordable than on the West Coast. Coal burns more efficiently and hotter than wood. Because of its efficiency, the volume of coal needed is substantially less, too.

What is forge coke?

FORGING COKE. Maximum heat, famously clean burning, and low clinker. Premium Metallurgical COKE burns much hotter and cleaner than coal. Especially processed and sized for use in blacksmith and farrier forges.

Can you use natural gas for a forge?

Hi-pressure natural gas is the right fuel for your forge ! Best of all, for equal heat performance natural gas costs a lot less than propane. If you pay $ 75 for a 100# propane tank it would cost less than $ 20 to get the same heat with natural gas!

Can you use motor oil to quench steel?

Motor oils are a common type of quenching oil used in both blacksmithing and bladesmithing applications. New and used motor oils can be used for quenching and are both widely available. New motor oil is typically cheaper to use than commercial quenching oils.

What is the difference between quenching in oil vs water?

Oil has a slower rate of cooling compared to either water or brine, but faster than air, making it an intermediate quench.

Can canola oil be used to quench steel?

Canola, Motor Oil, and the Inconel Probe Test

I found a study on 1045 steel where they found canola to quench more rapidly than motor oil so I am going to stick with canola as my “cheap” quenching option to test.

What do you dip hot metal in?

Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).

How long does quench oil last?

Oil Recovery

Quenching and martempering oils deteriorate during use, although most premium quenching oils can last more than 10 years when given reasonable use and care.

Why do blacksmiths use oil to quench?

Why Quench in Oil? Oil quenching is popular because of its severity; that is, it transfers heat more quickly compared to other quenching media like molten salt or gas.

Can you buy coal coke?

Centaur Forge offers a wide selection of bagged smithing coal and coke, including in bulk. Find blacksmith coal for sale at low prices, with shipping included in the cost.

Why is coke used instead of coal?

The single most important factor is strength ( mechanical compressive ); coal is heated to make coke, the resulting coke is stronger than the original coal. Also, coke helps to make the charge of iron oxides and limestone more porous to permit gas flow up and droplets of liquid iron and slag down.

What burns hotter coal or coke?

Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner.

Can you use wood to fuel a forge?

As you prepare the fuel for your forge, consider the amount of surface area of the wood. A large chunk of wood does not have as much exposure to oxygen as the same piece will when it is split smaller. The more surface area you have, the faster your wood will become charcoal and make a hot fire.

Why are there no titanium swords?

Titanium is not a good material for swords or any blades. Steel is far better. Titanium cannot be heat treated sufficiently to gain a good edge and will not retain edge.

Why do blacksmiths put metal in water?

Blacksmiths put metal in water because water submersion will allow the forger to control the brittleness and overall strength of the metal. This is referred to as “quenching,” and is used by many blacksmiths to decrease the risk of breakage when crafting new pieces.

Can you forge rebar?

Cons of Forging with Rebar

A first major con of using rebar for blacksmithing is its unpredictable nature. Most rebar is not made of quality metals and can even contain dangerous fumes when worked. What is this? You can never be sure what the rebar is made of, so final projects can end up brittle.
