Table 5. Density profile of ceramics according to the rate of mandarin peels addition

Rate of mandarin peels addition (%)	Dave (kg/m3)	Dmin (kg/m3)	Dmax (kg/m3)	Dmin/Dave (%)
5	858	770	1,106	89.7
10	755	639	1,006	84.7
15	794	661	1,067	83.2
20	821	657	1,081	80.0
25	754	622	964	82.5

D_ave: average of density, D_min: minimum of density, D_max: maximum of density, D_min/D_ave: minimum of density to average of density ratio.
