More accurately termed a refractory zinc pot, its core consists of a pot body constructed from special refractory materials such as silicon carbide. They boast exceptionally long lifespans exceeding 10 years, minimal zinc consumption and slag production, and high safety reliability. However, they entail high initial investment, slow heating rates, and challenging maintenance.

The Zinc Pot operates through the hot-dip galvanising process, immersing steel materials into molten zinc to form a protective zinc coating on their surfaces. This provides corrosion resistance and decorative benefits.
