Krypton adsorption studies demonstrated an easily accessible system of pores in enamel, measuring between 10 and 300 A, volume 0.26%, with a surface area of about 0.4 sq m/gm (BET analysis). These figures are much lower than is suggested by figures for water content, possibly resulting from nonpenetration of the organic matrix by krypton. Some measurements on demineralized enamel were also made.
