Natural Aging Characteristics of Gelatin Sizing Traditional Korean Paper Used Replicating of the Annals of the Joseon Dynasty

Type: article
Abstract: This study examines the changes in color and physical properties of non-sized and gelatin-sized samples of traditional Korean paper, produced in 2011 for replicating the Annals of the Joseon Dynasty, under two aging conditions: accelerated aging and natural indoor aging until 2022.Analysis showed that during natural aging, yellowing was less pronounced in gelatin-sized samples than in non-sized ones.In contrast, under accelerated aging, both types of paper exhibited excellent color fastness regardless of sizing.Air permeability increased during accelerated aging for gelatin-sized and non-sized samples, but it decreased significantly for gelatinsized samples during natural aging.Gelatin-sized paper displayed higher tensile strength, elongation, tensile energy absorption (TEA), burst strength, and folding endurance compared to non-sized samples.Following natural aging, both paper types showed increased tensile strength, elongation, TEA, burst strength, tear strength, and folding endurance compared to their original states before aging.Conversely, after accelerated aging, tensile strength, elongation, TEA, burst strength, and tear strength decreased for both types, though folding endurance showed minimal decline.Regardless of the aging method, tensile strength, elongation, TEA, and folding endurance were higher consistently higher in the laid direction, whereas tear strength was greater in the chain direction.
