Yes, calcium does sink in water
Marbles are denser than water, so they will sink when placed in water.
Potatoes are denser than water, so they sink when placed in water.
Glycerin is denser than water, so it will sink when placed in water.
Mercury is a heavy metal, it will sink in sea water.
it will sink of it will float.
Granite rock is denser than water, so it will sink when placed in water.
Lung tissue is denser than water and will sink when placed in it.
Eggs sink in water because they are denser than water. The density of an object determines whether it will float or sink in a liquid. Since eggs are denser than water, they sink when placed in it.
Flint typically sinks in water because it is denser than water. The density of flint is greater than the density of water, causing it to sink when placed in water.

Pushpins sink because they are denser than water. The pushpin's material, usually metal or plastic, is heavier than water, causing it to sink when placed in water.
A block sinks when placed in water because its density is higher than the density of water. Since objects sink in water if they are denser than water, the force of gravity acting on the block is greater than the buoyant force pushing it up, causing it to sink.
