## Description

Precise jewelry calculations for alloys, fineness, casting and scrap. Free core tools, Bench Log, plus optional permanent Lab, Materials and Academy upgrades.

Smelter is a precise pocket workbench for jewelers, jewelry students, teachers, and makers who work with precious metals.

Prepare alloys, adjust fineness, work with scrap, estimate casting weight, compare densities, calculate fine-metal content, and solve the everyday metal calculations that happen at the bench.

BUILT AROUND THE JOB IN FRONT OF YOU

Start with what you need to do:

• Prepare an alloy
• Correct fineness
• Calculate a casting
• Work with scrap

Smelter takes you directly to the right calculation and presents the result in a clear, practical way — including the amounts to weigh and the mathematics behind them.

CALCULATE WITH CONFIDENCE

Use Smelter for:

• Alloy and fineness calculations
• Raising or lowering purity
• Fine-metal content
• Scrap and mixed-metal calculations
• Casting-weight estimates
• Density conversions
• Precious-metal conversions
• Ring and stock calculations
• Workshop planning

BENCH LOG

Save useful calculations as workshop records so you can return to previous melts, batches, notes, measured final weights, and process results.

It turns a calculation into something you can actually refer to at the bench.

PRECIOUS METALS, NOT JUST NUMBERS

Smelter is designed around jewelry metals such as gold, silver, platinum, and palladium, with familiar fineness standards and practical workshop terminology.

OPTIONAL SPECIALIST EXTENSIONS

Smelter’s essential calculation tools are included. If you need more, permanent one-time extensions add deeper specialist capabilities.

SMELTER LAB
Go further with scrap mixing, advanced formulation, recipes, planning, and multi-element alloy work.

JEWELLER’S BENCH
Add production-focused tools for stock, ring blanks, geometry, investment, and workshop preparation.

MATERIALS LAB
Explore a detailed reference library of jewelry and fabrication materials. Compare metals side by side, understand density and working characteristics, and create custom supplier or measured material profiles for use in calculations.

SMELTER ACADEMY
Learn the principles behind the numbers through structured lessons covering purity, alloys, scrap correction, casting mathematics, melting, process control, and troubleshooting.

Interactive exercises connect theory directly to Smelter’s real calculators.

The Foundations path is included so you can experience the learning system before deciding whether to unlock the complete Academy.

FOR THE BENCH, CLASSROOM, OR STUDIO

Whether you are learning jewelry making, teaching metallurgy and calculation, preparing a casting, or working professionally with precious metals, Smelter is designed to make the numbers easier to understand and faster to use.

Precise when it matters. Calm when you need it.
