Lead has a relatively low melting point, making it suitable for molding into the shape you want. Melted and remodeled lead can have different applications; it is ideal for creating custom fishing sinkers, or even for creating strange shapes to balance the weight of a model car or plane. Learning how to melt lead is simple, but it must be done with extreme care and awareness.
Steps
Step 1. Prepare the container and heat source
Lead should be melted in a well-ventilated, non-fire-hazardous environment as it can generate harmful fumes and, if not handled with care, can cause fires. The best choice for the heat source is a portable oxyacetylene torch. The container should be a heavy metal container; so don't use a cooking pot.
Step 2. Put the lead in the container
Add more of it than you need, as some of it will solidify on the sides of the container when you pour it.
Step 3. Heat the lead until it melts
Turn on your heat source and adjust the flame, if possible, to the highest value. Apply the lead flame as directly as possible. Lead melts at a temperature of 328 degrees Celsius, so it will take some time to melt a large amount of it.
Step 4. Pour the molten lead into the mold
When it has melted, turn off the heat source and prepare to pour it into the desired mold. You will have to hurry as the lead will cool and solidify quickly. Take the container using temperature-resistant gloves, and shake it gently to eliminate air bubbles. Pour the lead into the mold. Be careful not to touch the container directly, as hot gases escape and can burn you.
Step 5. Wait for the lead to return to a safe temperature
After pouring the lead, wait for about 10 minutes. This ensures that the metal is at a temperature that can be handled safely.
Step 6. Remove any spills
The lead released from the mold will solidify on the surface on which it fell. It will not adhere very strongly, and you can remove it using a chisel or flat screwdriver.
Advice
Remember that the lead you use may actually be an alloy, and therefore also contain other metals. This can affect the result of the final mold
Warnings
- Always wear heavy gloves when working with lead, as lead dust can transfer very easily from your hands to your mouth, and you may therefore swallow it.
- Do not try to melt lead in a pure tin container, as tin has a lower melting temperature than lead.
- Make sure the mold is dry before pouring the lead into it. Moisture can cause an explosion and can cause molten lead to splash on your body.
