1. What metals can this Mini Metal Melting Furnace melt?

It's designed for melting precious and common metals such as gold, silver and aluminum. The listing also mentions steel—because steel requires much higher temperatures, confirm the unit's maximum temperature with the seller before attempting to melt steel or high‑melting alloys.

2. What capacity options are available?

Three capacity options are listed: 1 kg, 2 kg and 3 kg. Choose based on the batch size you plan to melt.

3. What voltage does the furnace use?

The unit is available in 110V and 220V versions. Confirm the model you order matches your local mains voltage and plug type.

4. What are the physical dimensions and weight?

Unit dimensions are 210 × 235 × 380 mm and the net weight is 7.35 kg. Single package size is 49 × 35 × 48 cm and single gross weight is 12.00 kg.

5. Does the furnace come with a crucible and accessories (tongs, lid, power cord)?

Package contents are not explicitly listed in the description. Many similar units include a crucible, power cord and basic tools, but you should confirm with the seller to know exactly what is included.

6. What is the maximum temperature of the furnace?

The product description does not state a specific maximum temperature. Typical melting points: aluminum ~660°C, silver ~961°C, gold ~1064°C, steel ~1370°C. Verify the unit's rated maximum temperature with the manufacturer before melting high‑temperature metals like steel.

7. How long does it take to melt metal?

Melting time depends on the metal type, charge size and chosen capacity. Small charges of aluminum or silver often melt in minutes; larger batches and higher‑melting metals will take longer.

8. Is this furnace suitable for jewelry casting?

Yes — it's marketed for jewelry making and hobby casting. For casting finished jewelry you’ll also need appropriate crucibles, investment materials, molds and safety gear, and you should follow recommended casting techniques (e.g., fluxing, skimming dross, controlled pouring).

9. What safety precautions should I follow when using this furnace?

Use the furnace in a well‑ventilated area, wear heat‑resistant gloves, eye protection, and a face shield as needed. Keep a suitable fire extinguisher nearby, never leave the furnace unattended while hot, and avoid combustible materials near the unit. Follow local safety and fire codes.

10. What crucible material should I use?

Graphite or ceramic crucibles are commonly used for gold, silver and aluminum. For some alloys or very high temperatures (e.g., steel) you may need a specialized crucible. Check compatibility of crucible material with the metal you plan to melt.

11. How do I maintain and clean the furnace?

Allow the unit and crucible to cool completely before cleaning. Remove dross and slag from the crucible after each use, inspect and replace worn crucibles, keep ventilation passages clear, and follow any maintenance instructions provided by the manufacturer.

12. Is this unit portable?

Yes. The furnace is compact and relatively lightweight (7.35 kg), making it easy to move and store. The package gross weight is about 12 kg for transport.

13. Can I use this furnace for recycling scrap metal and repairs?

Yes — it can be used for small‑scale recycling, melting scrap for casting, and repair tasks, provided the metals are compatible with the unit's temperature capability and appropriate safety measures are followed.

14. What should I consider when choosing between the 1 kg, 2 kg and 3 kg models?

Choose based on typical batch size, available workspace, power supply capability and portability needs. Larger capacities let you melt bigger batches but require more power and produce more molten metal to manage safely.

15. Is there a warranty or customer support available?

The product description does not list warranty details. Warranty and after‑sales support vary by seller. Check the seller's listing or contact the manufacturer for warranty, returns and technical support information before purchasing.
