Acid Vs Marble

Finish options for marble and quartzite.

Acid vs marble. An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. The hardness of marble vs. Stone surface material may be lost all over or only in spots that are more reactive. It is one of the most effective acid neutralization materials.

Comparing costs the price of marble and limestone can vary dramatically based on the color source and treatment of the stone. Quartzite is quite different. However sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled peeled off in some places revealing crumbling stone beneath. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.

However concrete acid stain possesses the unique property of creating a marble like effect without any additional staining techniques. Being composed of calcium carbonate marble will react in contact with many acids neutralizing the acid. It is used for acid neutralization in the chemical industry as well. Applications choose a commercial cleaner containing phosphoric acid and dilute it with water if instructed by the manufacturer.

Marble and quartzite can be finished in a variety of ways. For example while you can use phosphoric acid on ceramic porcelain and composite surfaces you should never attempt to use it on natural marble onyx granite or limestone. This acid etching can only be removed by professionally resurfacing and rehoning the stone. Marble has a moh s hardness rating of about 3 while quartzite has a rating of approximately 7.

This means that marble is much softer and will scratch easier than quartzite. This black crust is primarily composed of gypsum a mineral that forms from the reaction between calcite water and sulfuric acid.
