Greensand Casting

This is a picture of my first casting, just out of the sand.

Here is the flask ( cope and drag) that will hold the sand which forms the cavity mould.

This is the pattern in the cope, ready to be extracted.

The pattern has been removed, and cavities made for the sprue and riser. ( Where the metal is poured in.)
The white powder is talc (Baby powder ) used as a mould release.

Here is the drag, packed with sand and the patters for sprue and riser still to come out.

This is the flask assembled, with lead weights on top to keep the drag from floating on the liquid aluminium. The small pellet on top is a foil packet of pool chlorine powder that will be used to degas the molten metal before the pour.

This is the assembly after the pour, with a big lump of metal in the sprue, and some peeking out of the riser. This latter indicates that the pour filled the mould. The muffin tin holds the surplus that we do not want to leave in the pot to solidify.
