Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). Like most other sedimentary rocks, limestones are composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. i.e. travertine. The solubility of limestone in water and weak acid solutions leads to karst landscapes. Regions overlying limestone bedrock tend to have fewer visible groundwater sources (ponds and streams), as surface water easily drains downward through joints in the limestone. While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks; dissolving the calcium-carbonate and carrying it away in solution. Most cave systems are through limestone bedrock. From Wikipedia under the

We had really expensive limestone tiles fitted a few months ago in our kitchen, and one has now got a small dent/hole in it from having something heavy dropped on it. Apart from grout which will show too much, does anyone have any good ideas on how to repair it without replacing the tile? Asked by Netty - Tue Sep 25 04:31:05 2007 - - 5 Answers - 0 Comments A. if you have any of the original tiles left over you could grind a small corner of one up and mix the dust with clear setting araldite. Apply it to the spare tile to see how it looks when it sets. If it looks good then make some more paste and fill in the dent/hole.

VINEGAR... if constantly mixed or agitated, vinegar will effectively dissolve limestone with no problem however, if the limestone is left in the vinegar for a period of a few days to a week the result will be crystals of lime instead of the solid rock... experiment, place a golf ball size limestone in a beaker with vinegar in it, only up to half the height of the stone... let the vinegar soak in then evaporate and you will have a pretty despisee... add a copper penny or Even magnesium or iron and change the color of the limestone crystals... but in your case leave the limestone submerged 90% in the vinegar with only the highest point of the stone peaking out... this crystal is very brittle and is easily breakable by the human hand so if… [cont.] Answered by Wolff - Tue Oct 28 12:50:21 2008 From Yahoo Answer Search: "Limestone" |
