Graphite Crucible Boosts Efficiency in Metal Melting Industry
January 29, 2026
For metalworking enthusiasts or small foundry operators, finding the right crucible can make all the difference in metal melting projects. Standard crucibles often fall short—either too small, lacking heat resistance, or made from subpar materials that compromise performance. The LSMIITTH 25KG graphite crucible emerges as a superior solution, designed to meet the demands of serious metalworkers.
With dimensions of 7 inches (18 cm) in diameter and 9 inches (22 cm) in height, this crucible boasts a remarkable 25KG capacity. Its substantial size allows for efficient melting of various metals in significant quantities:
- 25 kg of copper
- 46.8 kg of gold
- 7.5 kg of aluminum
- 29.5 kg of silver
Whether crafting large copper sculptures or producing gold jewelry, this crucible streamlines the melting process, enhancing productivity for both professionals and hobbyists.
High temperatures are inherent to metal melting, making heat resistance a critical feature. The LSMIITTH crucible, crafted from premium graphite, withstands temperatures up to 1800°C (3300°F). This capability makes it suitable for melting a wide range of metals, including gold, silver, copper, brass, aluminum, and even glass, without risk of structural failure.
Graphite's excellent thermal conductivity ensures rapid, even heat distribution, reducing melting times. Its chemical stability prevents reactions with molten metals, maintaining purity and preventing contamination. These qualities make the LSMIITTH crucible both reliable and safe for consistent use.
To maximize the crucible's durability and performance, preheating is recommended. Heating the empty crucible to approximately 500°C for five minutes removes internal moisture and impurities, enhancing its resistance to thermal shock.
The LSMIITTH crucible serves diverse needs, from professional foundries to artistic metalworking. Its applications include:
- Jewelry making with precious metals
- Sculpture and art casting
- Metal recycling processes
Combining robust construction with practical design, this crucible stands out as an essential tool for anyone engaged in metal melting.
