A text-book of assaying : $b for the use of those connected with mines.

Designed as a compact, hands‑on reference for anyone working in a mine, this guide walks the listener through the fundamentals of assaying—the process of determining the precious metal content of ore. It begins by clearing up common misconceptions, explaining how modern assaying now embraces a broad range of metals and techniques rather than limiting itself to gold and silver alone. The author also adds concise notes on rarer elements that can throw off results, giving the listener a realistic sense of the challenges faced on the shop floor.

Packed with detailed diagrams, tables, and step‑by‑step experimental results, the book shows how variations in temperature, reagents, and timing affect accuracy, allowing listeners to picture each laboratory setup. It includes a once‑novel electrolytic copper method that was adopted by major mining operations across Europe, illustrating the text’s blend of theory and field‑tested practice. Ideal for students, seasoned assayers, or anyone curious about the science that underpins the mining industry, the narration brings a century‑old manual to life with clear explanations and practical insight.
