Abstract
A method of forming simulated marble articles from materials polymerizable within a cell or mould characterized in that the mould is filled under conditions in which the polymerizable materials are introduced as streams following the flow path into the cell or mould and the contents are polymerized with the cell or mould disposed so that the flow lines are on a height gradient relative to each other. Limited intermixing of the compositions during the initial stages of the curing process produce an attractive simulated marble effect. The mould may be filled so that the flow lines are disposed in a near vertical position and then rotated so that they are in a near horizontal position with adjacent flow lines on a near vertical height gradient.
