FAQ About Smelting Tools
Why does my crucible crack or the lid fall off after a few melting cycles?
+
High-temperature cycling increases structural stress. Low-density or recycled graphite cracks within 5–10 melts. Our high-purity crucible is rated for 50–100 cycles. Early cracking usually means poor material quality, not user error.
Why does it take 60 minutes to melt copper while others only need 20 minutes?
+
Real melting speed depends on actual wattage, insulation thickness, and temperature consistency. Some products claim “1400W” but deliver far less. A true 1400W+ furnace melts 300g copper in 20–25 minutes.
Will the furnace smoke, spark, or trigger GFCI during normal use?
+
No. Smoke, sparks, and frequent GFCI trips indicate electrical or coil insulation faults. A proper furnace uses thick insulation, grounded chassis, GFCI protection, and overheat safeguards.
Will the pliers or molds break or be too small?
+
Cheap pliers deform above 500°C. Good pliers must hold 1200°C red-hot crucibles safely. Molds under 100g capacity are impractical. A proper kit includes heat-resistant pliers and molds matching the crucible size.
Why do cheap furnaces become more expensive over time?
+
Thin crucibles, weak insulation, and low-grade electronics wear out faster. Real cost includes power usage, consumables, and downtime — not just the purchase price. Durable systems lower long-term cost per kilogram.
Does “Max 1100°C” mean accurate temperature control?
+
No. Max temperature ≠ stability. Many units swing ±50°C, causing oxidation and bubbles. A PID controller holds ±5°C accuracy, reducing defects by up to 75%.
How do I reduce carbon buildup inside the furnace?
+
Carbon builds up when the inner lining is rough. A removable, smooth alumina lining allows quick wiping after each melt and prevents residue from hardening.
Are the instructions difficult for beginners?
+
Beginners often skip steps like crucible preheating or grounding checks. If unclear, contact support or follow our video tutorials. Wrong operation can cause overheating or cracking.
Can I melt aluminum, silver, or gold?
+
Yes. Use high-purity graphite crucibles and match temperatures. Avoid cross-contamination by dedicating one crucible per metal.
