    AI Overview
    Cast iron crucibles are suitable for melting zinc and its alloys, offering good thermal conductivity and durability at the relatively low melting point of zinc (~420°C). They are commonly used for zinc, lead, and aluminum due to their resistance to oxidation compared to steel, although they can become brittle at high temperatures. 
    Key Considerations for Cast Iron Zinc Crucibles: 
    • Suitability: Ideal for low-temperature metals like zinc, lead, and aluminum, as they are durable and cost-effective.
    • Operating Temperatures: While zinc melts at 419.5°C, the crucible should handle operating temperatures around 450–500°C.
    • Sizes: Available in various sizes, ranging from small DIY pots to large, 1,000 kg industrial kettles for die-casting or galvanizing.
    • Maintenance: Cast iron pots can crack if exposed to extreme, rapid thermal shock or oxidation over time.
    • Alternatives: For higher purity, some, like Ditta Musto, suggest using welded stainless steel to avoid the brittleness of cast iron. 
    Safety Note: When melting zinc, always wear appropriate safety gear (heat-resistant gloves, face shield) and work in a well-ventilated area to avoid zinc fumes.
