Is propane gas buning to melt gold a physical change or a chemical change?
The process of burning propane gas to melt gold is a chemical change. When propane gas undergoes combustion, it reacts with oxygen to produce heat, light, and various byproducts such as carbon dioxide and water vapor. This chemical reaction results in the transformation of the propane gas into new substances, making it a chemical change.
Can you melt gold at home?
It is possible to melt gold at home using a torch or a kiln that reaches high temperatures. However, you should take safety precautions, such as wearing protective gear and working in a well-ventilated area, as melting gold involves working with extreme heat. It is advisable to have some experience or seek guidance from a professional before attempting to melt gold at home.
Can you Melt silver with a Bunsen burner?
No, a Bunsen burner does not produce enough heat to melt silver, which has a high melting point of 961.8 degrees Celsius. You would need a hotter heat source such as a torch specifically designed for melting metal.
If you use a blow torch what happens when you try to melt salt?
When you try to melt salt with a blow torch, the salt will initially absorb the heat and start to melt, becoming a liquid. However, if you continue to heat the molten salt with the blow torch, it will eventually evaporate and release fumes of sodium chloride.
Does wood or silver melt or burn faster?
Wood burns faster than silver because it has a lower melting point and is more flammable. Silver's high melting point makes it resistant to burning at standard temperatures, however, it can eventually melt under intense heat.
How do you melt sterling silver with a propane torch?
To melt sterling silver with a propane torch, you will first need a crucible or a heat-resistant container to hold the silver. Place the sterling silver in the crucible and heat it gradually with the propane torch, moving the flame around to evenly distribute the heat. Sterling silver has a melting point of around 1640°F (893°C), so ensure the flame is hot enough to reach this temperature for the silver to melt. Remember to take necessary safety precautions when working with high heat and molten metal.
What can melt water?
You can't melt water, as it is already melted. But if you mean ice, then take your pick. You can use fire, warm hands, your breath, sunlight, a hot lamp, an oxyacetylene torch, acetylene torch, propane torch, red hot metal, etc. Essentially anything warmer than 32 F (0 C) can melt water.
What type of torch should you use for soldering water heater fittings only?
Most use propane, but you can use acetylene also. Just as long as you don't get it too hot. Propane will not melt copper, but acetylene will.
How can I melt a wine bottle without a kiln?
To melt a wine bottle without a kiln, you can use a propane torch or a campfire to heat the bottle until it becomes malleable and starts to melt. Be sure to wear protective gear and handle the hot glass carefully.
What is a Propane torch's temperature in the blue flame?
A propane torch is a tool for burning the flammable gas propane. The maximum adiabatic flame temperature a propane torch can achieve with air (3,623 °F). Some propane torches are also used with a tank of pure oxygen.
How hot does the fire torch need to be when silver soldering?
Silver soldering typically requires a torch with a temperature range of 1300-1600°F (704-871°C) to melt the solder and create a strong bond between the metals.
How can I melt silver without using borax?
To melt silver without using borax, you can use a high-temperature torch or furnace. Heat the silver until it reaches its melting point of 1,763 degrees Fahrenheit, then carefully pour it into a mold or container to cool and solidify.

How do you torch a cooper pipe in an air conditioning system?
If installing or replacing a copper line on an AC unit you must 'braze' the line with an acetylene and air tank mixture. Use 10 psig on the O2 tank and 5 psig on the acetylene tank. You will need a need a 'neutral' flame. You can not get enough heat by using a propane torch. You will need enough heat to melt the 5% silver solder.
Can you melt gold at home?
It is possible to melt gold at home using a torch or a kiln that reaches high temperatures. However, you should take safety precautions, such as wearing protective gear and working in a well-ventilated area, as melting gold involves working with extreme heat. It is advisable to have some experience or seek guidance from a professional before attempting to melt gold at home.
What is a suitable source of heat for brazing?
A suitable source of heat for brazing is typically a torch fueled by a gas such as acetylene, propane, or natural gas. This type of torch provides a high enough temperature to melt the brazing material without melting the base metals being joined.
When soldering copper pipe and use the propane torch and how much open the vertical valve?
What valve?...on the torch? Open it up enough to play a good flame. If you are soldering on a valve, you need to take out the valve stem from the body unless you want to melt the seats. Opening the valve is not enough.
