Concentrate on native legal guidelines or restrictions relating to the acquisition and use of lead. Widespread sources embody outdated plumbing elements or wheel weights. At all times examine the lead supply rigorously earlier than melting it. Take away any international supplies, equivalent to plastic, rubber, or rust, as these can contaminate the lead or generate harmful fumes when heated.
Melting Furnace/Melting Pot
You will want a melting furnace or melting pot. There are a number of choices out there. An electrical furnace gives a extra managed and constant warmth supply, which might be a bonus. Propane torches used with a cast-iron pot are another choice. These will want extra consideration, however can work properly. *Observe: At all times learn and cling to the producer’s directions and all security data for any tools you utilize.* Watch out about utilizing a Crock-Pot, as these are designed for low-temperature cooking.

If they’re used, they’re usually used for very small batches of lead solely, and even then needs to be approached with nice warning and are usually not advisable for rookies.
Thermometer, Skimming Instruments, Molds, and Containers
A thermometer is crucial. A non-contact or immersion thermometer will allow you to monitor the lead’s temperature precisely, which is essential for controlling the method and minimizing the formation of dross. You will want instruments to skim dross from the floor of the molten lead. These can embody a ladle or a heat-resistant spoon. In case you plan to forged the lead into particular shapes, equivalent to fishing weights or bullets (topic to authorized restrictions), you will want acceptable molds or casting tools. Lastly, you will want containers to carry the molten lead and permit it to chill safely. Steel containers are an excellent possibility, as are containers fabricated from a heat-resistant materials.
The Step-by-Step Course of
Preparation
With the required tools and precautions in place, you’ll be able to proceed to soften the lead. It is a step-by-step course of that have to be adopted rigorously. Preparation is paramount.
