What Would You Do With A Limestone Rock?
Limestone is a fine-grained sedimentary
rock that forms when calcium carbonate precipitates in a quiet ocean environment
such as deep, calm water. You cannot see individual grains with the naked eye in
a fine-grained rock. Limestone is often white, pink, red, gray or black.
Fossils are common in limestone because the calm ocean allows the calcium
carbonate to precipitate around a dead plant or animal part without significantly
disturbing the specimen. There are many varieties of limestone. Coquina consists
of mostly animals parts, such as shells, that are glued together by calcium 
Limestone is useful in your home as attractive tiles and building stones. The variety of colors and types of limestone along with fossil rocks give these building materials a unique look. You can use limestone blocks and gravels to construct buildings, walls and garden paths. Crushed limestone mulch is beneficial for some plants in the garden because it helps to raise the soil pH before you install shrubs. Limestone’s biggest limitation is that it will dissolve in acid over time so it may pit from rain.
We have a great selection of limestones including fine-grained, coquina, oolitis and fossiliferous for your projects and collections.
