Introduction
EUROGRAFITE s.r.l. is an Italian manufacturer with deep specialisation in graphite-based products for industrial and precious metal processing applications. Their crucible range is built for one purpose: reliable, consistent performance under the extreme thermal conditions of metal melting — batch after batch, shift after shift.
In jewellery manufacturing and precious metal processing, the crucible is not a passive container. It is an active part of the melting process — influencing heat distribution, metal cleanliness, contamination risk, and the longevity of the melt cycle. A poor-quality crucible cracks under thermal stress, contaminates the melt, or degrades faster than expected, adding cost and downtime to the production floor. EUROGRAFITE’s graphite crucibles are engineered to avoid exactly these failures.
NJTPL has been supplying EUROGRAFITE crucibles to Indian jewellery manufacturers, casting facilities, and precious metal refiners — providing genuine product access, technical guidance, and local support from Mumbai.

Why the Right Crucible Matters in Jewellery Manufacturing
Every time precious metal is melted — for casting, alloying, or refining — the crucible it melts in directly affects the outcome. A crucible that is chemically incompatible with the metal, unable to handle the required temperature, or structurally weak under thermal cycling will cause problems that show up in the finished metal: contamination, porosity, inconsistent flow, or worse — a cracked crucible mid-melt and lost material.
EUROGRAFITE crucibles are made to eliminate these variables. High-density graphite construction gives them:
- Excellent thermal conductivity — heat distributes evenly through the melt, reducing hot spots and improving metal homogeneity
- High thermal shock resistance — they withstand rapid heating and cooling cycles without cracking
- Chemical stability — graphite does not react with gold, silver, platinum, or their common alloying additions
- Long service life — correctly used EUROGRAFITE crucibles outlast cheaper alternatives significantly, reducing per-melt cost
- Clean melts — high-purity graphite minimises contamination risk in the precious metal charge
- Consistent geometry — precision-manufactured crucibles fit standard melting equipment correctly and pour predictably
For Indian jewellery manufacturers and refiners melting gold, silver, and platinum alloys in torch furnaces, induction units, or resistance melters, the right EUROGRAFITE crucible grade makes the melting process more controlled, more repeatable, and more economical.
Product Range
Various Crucibles
EUROGRAFITE manufactures a range of graphite crucibles in multiple sizes, geometries, and grades — covering the full spectrum of precious metal melting applications from small goldsmith bench work to large-scale casting and refining operations. The range includes standard graphite crucibles, clay-graphite crucibles, and silicon carbide graphite crucibles, each suited to different furnace types, temperature requirements, and metal charges.
NJTPL can help identify the correct EUROGRAFITE crucible grade and size for your specific melting equipment and metal type.
Why Indian Jewellers & Refiners Choose EUROGRAFITE Through NJTPL
Built for precious metal melting
EUROGRAFITE crucibles are chemically stable in contact with gold, silver, and platinum alloys — no unwanted reactions, no contamination of the melt, no risk of the crucible material compromising the precious metal charge.
Thermal shock resistance that holds up in production
Indian workshops frequently run multiple melt cycles per shift. EUROGRAFITE’s graphite construction handles rapid thermal cycling without cracking — significantly reducing crucible failure and the material loss that comes with it.
Consistent geometry for predictable pouring
Precision-manufactured crucibles fit standard melting equipment correctly and pour at consistent angles — which matters when you are filling moulds under time pressure at casting temperature.
Long service life reduces per-melt cost
A crucible that lasts 30% longer is a crucible that costs 30% less per melt. EUROGRAFITE’s construction quality translates directly into a lower cost per use compared to lower-grade alternatives commonly available in the Indian market.

Frequently Asked Questions
What types of crucibles does EUROGRAFITE manufacture?
EUROGRAFITE produces graphite crucibles, clay-graphite crucibles, and silicon carbide graphite crucibles across a range of sizes and geometries. Each type is suited to different furnace types, operating temperatures, and metal charges. NJTPL can advise on the correct grade for your specific melting setup.
Are EUROGRAFITE crucibles suitable for melting gold, silver, and platinum?
Yes. EUROGRAFITE graphite crucibles are chemically stable in contact with gold, silver, platinum, and their common alloying additions. They are widely used in jewellery manufacturing and precious metal refining applications precisely because they do not react with or contaminate the metal charge.
Which EUROGRAFITE crucible is right for my induction melting furnace?
The correct crucible depends on your furnace size, operating temperature, and the metal charge weight. NJTPL can help you identify the right EUROGRAFITE grade and size for your specific induction unit — contact us before ordering to avoid a mismatch.
How do I extend the service life of a graphite crucible?
Correct preheating before first use, avoiding thermal shock from cold charging, and storing crucibles dry in a stable environment are the key practices. NJTPL can provide specific guidance for your crucible grade and furnace type.
Can I use the same crucible for different precious metals — gold and silver, for example?
It is generally advisable to dedicate crucibles to a single metal type to avoid cross-contamination. This is especially important where alloy composition and hallmark compliance are critical. NJTPL can advise on a dedicated crucible strategy for multi-metal production environments.
Where can I buy EUROGRAFITE crucibles in India?
