Abstract
Disclosed is a resin-aggregate mixture comprising polyurethane resin, aggregate (sand), silane compounds, iron oxide and powdered thermoplastic resins. Flower pots from this composition are cured either with a tertiary amine, base, or metallic ion. The cured pots subsequently are baked at a temperature sufficient to fuse the thermoplastic resin to provide a pot having air permeability but resistance to the permeation of water.
