This study investigated the effect of particle size variation of (150 µm, 125
µm & 100 µm) waste soda lime glass on the physical and mechanical properties of
unglazed stoneware tile. The linear shrinkage result reveals that the smaller particles
lead to higher shrinkage, in contrast to the tile body incorporation of larger particle
sizes WSLG.The water absorption and apparent porosity was observed during the
experiment and gives a high percentage due to low firing temperature. This failure did
not reach the standard WA (Water Absorption) emphasizes the critical importance of
firing temperature in achieving full vitrification. Optimal bulk density is observed
with a 125 µm particle size (1.78/cmᶾ), while 100 µm and 150 µm sizes result in
slightly lower bulk densities. In terms of mechanical properties, particle size of 125
µm and 150 µm shows lower modulus of rupture, while 100 µm exhibiting the
highest value (3.35 Mpa). These findings collectively emphasize complex interplay of
particle size, offers insight into the material science field implication for maximizing
the use of waste materials in ceramic manufacturing.
