Calcium black outline icon

About the Calcium black outline icon

This icon shows a rounded square tile from the periodic table: a large capital C with a lowercase a forming the element symbol Ca, and the atomic number 20 placed in the upper right corner. It communicates the mineral calcium, bone health, dietary nutrients and chemistry teaching. Use it on supplement labels, nutrition facts panels, dairy product pages, health apps and school science materials.

The frame is a square with softly rounded corners and an even inner margin; the symbol dominates the lower left while the number sits small and high, mirroring real element card layouts. It pairs with vitamin, iron, magnesium and molecule icons. Because the 20 is fine detail, use it at 40 px or larger.

This is the black outline version of the calcium icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
