The art of giving form to metals by fusion casting, forging, drawing, hammering, stamping, boring filing, chizzling grinding, bending, soldering.
paragraph
Sciences from which the operations in all the branches of this art may be improved.
Natural philosophy as it relates to the laws of motion.
Chemistry
In perfecting the preparation of metals so as to give them the qualities of:
1. Malleability 2. Hardness 3. Uniformity of texture 4. Elasticity 5. Power of bearing sudden expansion or contraction by heat without breaking
And in pointing out the means by which the above qualities may be given or removed avoided the giving during the various operations in their manufacture.
paragraph
Information caution dexterity necessary for the practice of all the branches of this art.
paragraph
Casting by pouring where the intended form is already made in the mould.

Dexterity in pouring the fluid metal into the mould so as not to disarrange its parts.
Iron founder Plumber
paragraph
Information cautions dexterity necessary for the practice of casting metals by pouring. As also in the art of giving form by casting to
glass compositions uniform substances the fluid at the heart of boiling water powders united mixed with fluids
A knowledge of natural philosophy in as far as relates to expansion and contraction by change of heart, or degree of moisture, deleted text with a view to accuracy of form, or strength & uniformity of texture.
Relative powers of different bodies to conduct heat.
Effect of the presence or exclusion of air.
Difference of the specific gravity of mixtures with a view to uniformity of texture.
Effect of sudden expansion or contraction fropm sudden & unequal change of temperature.
Dexterity in pouring the fluid metal into the mould.
paragraph
Sciences from which an improvement of the art of casting may be derived
natural philosophy
with respect to the means of excluding permanently elastic or other elastic fluids 7 non-elastic fluids.
Chemistry
With respect to the prevention of the generation of elastic fluids. With respect to the degree of heat at which particular metals or mixtures of metals can be cast so as to receive the desired form most perfectly & at which the metal will retain an homogeneous unchanged form in cooling.
