Melt lead safely and without bubbles


Lead can be melted well due to its low melting point. For weights in fishing or model making weights of lead can be poured in any shape. Since lead melting produces a toxic effect of the heavy metal in several ways, careful preparations must be made.

Hot lead splashes on water

The melting point of lead is reached at 327 degrees Celsius. This temperature can already be generated with a large candle. In order to facilitate a uniform and continuous melting, the use of a camping stove or Bunsen burner is recommended. Important is a fireproof vessel that is dry. When lead meets water, it splatters.

The heavy metal lead is poisonous and must only be melted with protective gloves. Ideally, it will be melted in the well-ventilated outdoor area. In closed rooms a respirator mask should be put on. The liquid lead must be poured immediately into the prepared molds or vessels.

How to melt lead

  • lead ingots
  • Bunsen burner or camping stove
  • Protective gloves
  • If necessary, respiratory protection
  • Tundish with handle
  • molds

1. Distribute lead

Depending on the initial shape, distribute the lead blanks in the melting vessel. This pouring vessel with handle should be filled as evenly as possible. Handle the blanks only with gloves, as even the skin contact transmits poison.

2. heating

The safest way to heat up is with a hand burner, which you hold from above over the lead blanks. The lead "floats" after a few minutes and can be poured out. Fill it in the provided molds. The surface should be level, clean, hard and non-combustible.

3. Swing out air bubbles

If air bubbles are forming in your molten lead, move the casting vessel in a slow, circling direction, sweeping out the trapped air.

4. Clean the casting vessel

Assume that you can no longer clean your tundish from all lead attachments. Therefore only use workshop containers and never cookware. Clean the tubes with acid dilutions and then with soda solution.

Tips & Tricks

When swinging trapped air, pay attention to the inertia of the molten metal. It "rocks" in too strong movements and can quickly spill over.
