LARGE PRODUCTS ARE FEASIBLE. A MULTI-LAYERED PRODUCT WALL IS CONSTRUCTED USING FOR EXAMPLE AN OPTIONALLY DYED EXTERIOR AND FOAMING GRANULES IN A MIDDLE LAYER. A BELL-SHAPED PRODUCT CAPABLE OF CONVERSION INTO A DWELLING IS MADE IN THIS MANNER INSIDE A METAL MOULD, OPEN AT ONE END AND SLOWLY ROTATING ABOUT A HORIZONTAL AXIS IN AN OVEN.</p> |
