Meaning and Definition
A mixture of impure metallic arsenides and antimonides, produced as a byproduct in the smelting of certain ores, particularly cobalt and nickel.
In metallurgy, a dense, metallic, crystalline regulus formed during the smelting process, often containing valuable metals like cobalt, nickel, silver, or arsenic, and requiring further processing to recover them. It is analogous to matte in copper smelting but specifically associated with arsenical and antimonial ores.

FAQ
Frequently Asked Questions
No, it is an extremely rare and specialized technical term from metallurgy, mostly of historical interest.
It is pronounced /spaɪs/, rhyming with 'ice' or 'dice'.
Almost certainly not. It would be incomprehensible to nearly all listeners unless they are historians of metallurgy or industrial archaeologists.
In smelting: Slag is the waste silicate layer. Matte is a sulphide intermediate (e.g., copper matte). Speiss is an arsenide/antimonide intermediate, denser than slag and associated with different ores.
A mixture of impure metallic arsenides and antimonides, produced as a byproduct in the smelting of certain ores, particularly cobalt and nickel.
Speiss is usually technical / historical in register.

Mnemonic
Think: 'SPEcial mIXture of metals' or 'SPEISS = Smelting Product, Essentially Impure, Solid Substance'.
Conceptual Metaphor
A speiss is a 'treasure chest' of valuable metals locked in a toxic, impure matrix that requires a key (further refining) to open.
