I believe you are looking at mica ( The mica group of sheet silicate minerals includes several closely related materials having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudo-hexagonal crystals and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. The word "mica" is thought to be derived from the Latin word micare, to glitter, in reference to the brilliant appearance of this mineral (especially when in small scales). Mica has a lamellar form with a shiny luster.), not formica (Formica is a brand of composite materials manufactured by the Formica Corporation based in Cincinnati, Ohio, United States. In common use, the term refers to the company's classic product, a heat-resistant, wipe-clean, plastic laminate of paper or fabric with melamine resin.)
I wasn't expecting to learn so much more about cleavage; if I were younger, I just might be confused!!
