Abstract: This research explored the possibility of oyster shell powder mixed with mica pearl powder, and beeswax. The study aimed to determine the physical properties of the Pearl Crayons in terms of visual appearance, firmness, vibrancy, texture, finished product and its fusibility, acceptability when applied to coupon bond, vellum board, and illustration board as well as the significant difference in three (3) treatments: Treatment A (5g oyster shell powder, 5g mica pearl powder, and 20g beeswax), Treatment B (10g oyster shell powder, 5g mica pearl powder, and 20g beeswax), and Treatment C (15g oyster shell powder, 5g mica pearl powder, and 20g beeswax). The instrument used in gathering the data is a sensory evaluation score sheet. The acceptability of the crayons will be evaluated among a limited sample of fifty (50) participants, likely to include thirty (30) learners, ten (10) teachers, and ten (10) artists. The data was tabulated and statistically analyzed by SPSS software using the Arithmetic Mean and the Analysis of Variance (ANOVA).

The physical properties of pearl crayons showed that statistically treatment A (5g oyster shell powder, 5g mica pearl powder, and 20g beeswax) got the highest mean. The fusibility of pearl crayons, statistically treatment A (5g oyster shell powder, 5g mica pearl powder, and 20g beeswax) got the highest mean. The level of acceptability of pearl crayons statistically showed that Treatment A (5g oyster shell powder, 5g mica pearl powder, and 20g beeswax) got the highest mean. Additionally, the level of acceptability results of pearl crayons when applied to coupon bond, vellum board, and illustration board, statistically showed that Treatment A (5g oyster shell powder, 5g mica pearl powder, and 20g beeswax) got the highest mean. The significant differences found in the pearl crayons sensory qualities were visual appearance, vibrancy, texture, and finished product. But, for firmness it clearly showed no significant difference between treatments. Further research could look at different changes or treatments to improve their visual appearance, firmness, and texture. Educational institutions and art organizations should incorporate information about pearl crayons into their curricula and workshops, raising awareness about their environmental benefits and artistic potential. This fosters greater adoption of sustainable, non-toxic, and eco-friendly crayons practices among emerging and established artists alike.
