Abstract: CARAIG, MARY GRACE P.; CUEVAS, JULIE R.; FEDERICO, RYAN P.; and JIMENO, MA. IRENE T., Applied Research 111 (General Science Curriculum), Cavite State University, Indang, Cavite, February 2000, "UTILIZATION OF VOLCANIC ASH IN THE MANUFACTURE OF GLAZED-CERAMICS." Advisers: Engr. Ruel Mojica, Prof. Dulce Ramos The study entitled "Utilization of Volcanic Ash in the Manufacture of Glazed-Ceramics" was undertaken to utilize volcanic ash in the manufacture of glazed-ceramics. It also aims to (a) evaluate the quality of the produced ceramics in terms of hardness and dryness; (b) determine the appropriate proportion of volcanic ash and clay that will produce good quality ceramics; and (c) estimate the cost and return of pr00ducing ceramics out of volcanic ash. The study was conducted at MSD-ITDI, Department of Science and Technology, Bicutan, Taguig, M.M. from August to December 1999. The proportions used in the study were Treatment 0. 100 g. 110-110 Black Ball Clay, 50 g. Feldspar and 350 g. Red Clay; Treatment 1.100 g. 110-110 Black Ball Clay, 100 g. volcanic ash, 50 g. Feldspar and 250 g. Red Clay; Treatment 2. 100 g. 110-110 Black Ball Clay, 175 g. volcanic ash, 50 g. Feldspar and 175 g. Red Clay; Treatment 3. 100 g. 110-110 Black Ball Clay, 250 g. volcanic ash, 50 g. Feldspar and 100 g. Red Clay; and Treatment 4. 100 g. 110-110 Black Ball Clay, 350 g. volcanic ash and 50g. Feldspar. Highly significant results were obtained in the parameters such as mass of unfired, fired, freshly glazed and finished products; volume change of unfired and fired ceramics; moisture content; and production cost of the produced products. However, non-significant results were obtained from volume and densities of unfired, fired, freshly glazed, and finished ceramic products; volume changes and density changes of unfired and fired ceramics. The lowest firing shrinkage was observed in Treatment 3 composed of 20% 110-110 Black Ball Clay, 50% volcanic ash, 10% Feldspar and 20% Red Clay with a firing shrinkage of 6.387 cm. Meanwhile, the highest firing shrinkage was observed in Treatment 0 composed of 20% 110-110 Black Ball Clay, 10% Feldspar and 70% red Clay with a firing shrinkage of 36.923 cm 3. It was proven that pure clay is still the most advisable material for glazed ceramic production, although the proportion 20% 110-110 Black Ball Clay, 50% volcanic ash, 10% Feldspar and 20% Red Clay can also be utilized. In terms of economic feasibility, Treatment 4 composed of 20% 110-110 Black Ball Clay, 70% volcanic ash and 10% Feldspar obtained the lowest cost of production of only P8.30 per piece.
