The present disclosure relates to casting cores. The teachings thereof may be embodied in methods for producing a slip and components produced using such methods. For example, a method for producing a slip may include: mixing at least one inorganic constituent with at least one binder, wherein the binder comprises at least one epoxy resin and at least one silicone copolymer.

An apparatus for supplying a material to be formed to a plant for producing slabs. The apparatus comprises supplying means for supplying the material, a first means for collecting and moving, a conveyor cassette and second means for collecting and moving. The supplying means take the material from reservoirs and deposit it on the first means to form a semi-finished mat. The first means provide a stable base for the material and move the semi-finished mat towards the conveyor cassette, which receives the semi-finished mat and deposits a uniform pad on the second moving means. The second means provide a stable base for the uniform pad and move it towards successive stations in the plant. The walls of the conveyor cassette, in use, at least partly support the materials weight and comprise active surfaces The conveyor cassette has, an angled shape, comprising a first rectilinear portion and a curved one.
