';SHRINKAGE: Latex Foam shrinks about 10% and is more pronounced in large, thick pieces. Scaling up your sculpture is the answer. Foam from molds that have been ‘Cored Out’ will shrink less and more evenly than solid foam castings. Foam made with high solids latex shrinks the least.';





';LIGHT: Exposure to strong light will rapidly degrade latex. Ultra violet (UV) rays cause the deterioration. Performing outdoors in full sunlight or in environments lit with black (UV) light will shorten the life span of latex puppets.';
