Loam-moulding
Loam-moulding differs from sand-moulding in that the moulds proper are not contained in flasks, or bedded in the floor, but are constructed in sections composed of rings, plates, and brickwork. Another chief difference is that sand-moulds are simply impressions of a model that is furnished by the pattern-maker, whilst loam-moulds are in some measure the handiwork of the moulder himself, unaided by the pattern-maker in many instances.
There are instances where of necessity the operations necessary for the successful construction of a high-class loam-mould must include the three chief systems combined, viz., pattern, strickle, and spindle, with ample opportunity throughout the task for supplementing these systems by a nicety of touch which may be acquired only by constant practice and close application by the most intelligent moulders.
