What This Calculator Does
Sterling silver is a silver rich alloy. It normally contains 92.5 percent silver. The remaining part is usually copper. A melt estimate helps you plan before metal enters the crucible. It also helps when scrap pieces have mixed weights, fees, and losses.
Why Melt Math Matters
A small error can change expected value. It can also change furnace time. This calculator converts your chosen weight unit into grams. It then estimates fine silver, base metal, recoverable weight, melt value, and heating energy. You can enter assay strength when the alloy is not true sterling. You can also include loss, refining fees, and electricity price.
Chemistry Behind Sterling Melting
Melting is a physical change. The alloy changes from solid to liquid. Its atoms gain energy and move more freely. The calculator separates sensible heat, fusion heat, and optional superheat. Sensible heat raises the alloy temperature. Fusion heat changes the solid alloy into liquid metal. Superheat raises liquid metal above its melting point for pouring.
Workshop Use
Use clean scrap weights. Remove stones, steel springs, solder lumps, and dirt when possible. These materials can reduce accuracy. Enter a realistic melt loss. Small bench melts may lose more than controlled refinery melts. Use a conservative loss when valuing customer scrap. Always follow local safety rules. Hot metal can burn skin and ignite nearby materials.
Value Planning
The melt value is based on fine silver weight. Fine silver is the actual silver inside the alloy. Sterling is not valued as pure silver by weight. The calculator converts recoverable silver into troy ounces. It multiplies that amount by your silver price. Then it subtracts any refining or processing fee.
Better Decisions
The result is an estimate, not a settlement statement. Assay, scale accuracy, moisture, contamination, and market price can change the final payout. Still, the calculator gives a practical planning range. It shows the chemistry, mass balance, and energy picture in one place. Use it before buying scrap, quoting a melt, or scheduling a pour.
Record each batch after weighing. Keep notes on purity, melt loss, charge size, and energy use. Good records improve future estimates. They also support fair pricing, cleaner planning, and safer production routines for repeated work.
