The evil eye, known as μάτι (mati), "eye", as an apotropaic visual device, is known to have been a fixture in Greece dating back to at least the 6th century BC, when it commonly appeared on drinking vessels. In Greece, the evil eye is cast away through the process of xematiasma (ξεμάτιασμα), whereby the "healer" silently recites a secret prayer passed over from an older relative of the opposite sex, usually a grandparent. Such prayers are revealed only under specific circumstances, as according to their customs those who reveal them indiscriminately lose their ability to cast off the evil eye. There are several regional versions of the prayer in question, a common one being: "Holy Virgin, Our Lady, if [insert name of the victim] is suffering of the evil eye, release him/her of it." Evil repeated three times. According to custom, if one is indeed afflicted with the evil eye, both victim and "healer" then start yawning profusely. The "healer" then performs the sign of the cross three times, and emits spitting-like sounds in the air three times. Another "test" used to check if the evil eye was cast is that of the oil: under normal conditions, olive oil floats in water, as it is less dense than water. The test of the oil is performed by placing one drop of olive oil in a glass of water, typically holy water.
The moulding sand becomes incorporated into the casting metal and decreases the ductility, fatigue strength, and fracture toughness of the casting. This can be caused by a sand with too little strength or a pouring velocity that is too fast. The pouring velocity can be reduced by redesigning the gating system to use larger runners or multiple gates. A related source of defects are drops, in which part of the moulding sand from the cope drops into the casting while it is still a liquid. This also occurs when the mould is not properly rammed.The second type of defect is metal penetration, which occurs when the liquid metal penetrates into the moulding sand. This causes a rough surface finish. This is caused by sand particles which are too coarse, lack of mould wash, or pouring temperatures that are too high. An alternative form of metal penetration into the mould known as veining is caused by cracking of the sand. If the pouring temperature is too high or a sand of low melting point is used then the sand can fuse to the casting. When this happens the surface of the casting produced has a brittle, glassy appearance.A run out occurs when the liquid metal leaks out of the mould because of a faulty mould or flask.Scabs are a thin layer of metal that sits proud of the casting. They are easy to remove and always reveal a buckle underneath, which is an indentation in the casting surface.
