Sorry, no etymologies found.
In the high furnace, _peat-coal_, when compact and firm (not crumbly) may replace charcoal perfectly, but its cost is usually too great.
In hearth puddling, it is important not only that the peat or peat-coal contain little ash, but especially that the ash be as free as possible from sulphates and phosphates, which act so deleteriously on the metal.
When peat or peat-coal is employed in smelting, it must be as free as possible from ash, because the ash usually consists largely of silica, and this must be worked off by flux.
