CANALHOUT Silicon Carbide Graphite Crucible 700ML - High Temp 1800C

In this review the CANALHOUT silicon carbide graphite crucible is evaluated for hobbyists and small shop users who melt nonferrous metals at home. The bottom line: it is a practical, heatresistant crucible that stands out for its ability to withstand up to 1800C, making it suitable for melting aluminum, silver, gold and copper when paired with a compatible furnace. It is best for people who need a compact 700ML vessel that fits propane melting setups and other fuel furnaces without paying for larger industrial crucibles.

Key Features

• High temperature tolerance: Rated to 1800C so it can handle most hobby and light foundry operations without early failure.
• Material and durability: Made from silicon carbide graphite for thicker walls and a longer life, quoted as 2-5 times longer than clay alternatives.
• Compatibility: Designed to fit CANALHOUT propane melting furnaces but also works in other fuel furnaces, kilns and gas setups.
• Practical capacity: The 700ML volume is a convenient size for small pours and is shown against a 330ML beverage can for scale.
• Compact dimensions: Inner diameter 102MM, outer diameter 128MM and height 145MM make it easy to handle and position in many furnaces.

Who It's For

This crucible suits hobby jewelers, small metal casters and DIYers who need a compact, reliable vessel for melting aluminum, gold, silver and copper at home. It is helpful for those using propane furnaces, natural gas, pellet burners or coal-fired setups where a robust crucible is required.

It is not targeted at high-volume industrial foundries that need very large capacity crucibles or specialized alloy processing. Buyers expecting large pours or continuous production runs should consider larger industrial-grade options.

Pros & Cons

Pros

• Good thermal performance with a 1800C rating that covers most hobby metalwork.
• Thick walls and sturdy construction which customers cite as improved durability over clay crucibles.
• Compact 700ML capacity that fits many small furnaces and makes handling easier for one person.
• Clear dimensional specs and compatibility information make it simple to match to existing equipment.

Cons

• Mixed reports on early-life deterioration mean some users may see shorter life on first uses; proper firing and handling are important.
• The 700ML size may be too small for users who need larger single pours or batch processing.
