Here, the costs are not as low as with pure quartz sands. Other minerals, for example chrome ore or zircon sands, are common when a high density of the molds or cores is required (see ). Artificial sands, although substantially more expensive, are also common. Here, mostly Al 2 O 3 or SiO 2 are used as the base.
