Domestic Encyclopædia (1802)/Firing-iron

FIRING-IRON, in farriery, is an instrument resembling the blade of a knife; which, being made red-hot, is applied to the hams, or to such other parts of a horse as may require it, for the purpose of cauterizing and discussing preternatural swellings, such as farcy, knots, &c.—This operation is called firing.
