Surface crystallization of a Au$sup +$-ion-implanted lithia-alumina- silica glass was realized. Annealing of a glass sample implanted with 285-keV Au$sup +$ ions at 550$sup 0$C results in the growth of colloidal Au particles of 18 to 35-A radius. The Au particles constitute sites for the precipitation of lithium metasilicate crystals at 550$sup 0$C. Further annealing at 750$sup 0$C allows the growth of quartz and $beta$-spodumene crystals. The crystallized surface obtained after the high-temperature anneal was characterized by a Knoop microhardness number of 626, which is of the order of that obtained for commercial volume-crystallized glass-ceramics of similar composition.
