Limestone Worktops

Limestone Worktops Introduction:

The limestone countertop is derived from a sedimentary rock, generally light in colour. It primarily comprises minerals like aragonite and calcite, which are different crystal forms of calcium carbonate (CaCO3). Their origin can be traced back to biological and chemical processes that occurred in the marine lifeforms hundreds of millions of years back, formed either from the build-up of organic debris like coral reefs, algae, faecal materials, shells, etc or the process of chemical sedimentation like calcium carbonate precipitation from marine water-bodies.

Limestone countertops are used for kitchen hoods, bathrooms, and flooring.

Uses Of Limestone:

It is commonly used in architecture to build walls, decorative items, indoor-outdoor floors, and cabinet surfaces.

As a raw material for cement production, mortar, slaked lime (calcium hydroxide) and quicklime (calcium oxide).

Historical Significance Of Limestone:

Limestone countertops can be admired and used by ancient sculptors for their work simplicity and excellent carving properties. There is evidence of redefined sculptures made of Limestone by the Mayan people from the preclassic period, which dates back to almost 200-100 BCE. These sculptures were carved with social and political messages the king wanted to convey to his people. The Maya would also decorate the ceilings and cover walls of sacred buildings with Limestones.

Limestone regained popularity in the late 19th and early 20th centuries when limestones were used for building banks and train stations, exteriors of skyscrapers, etc. Many mediaeval castles and churches in Europe also show traces of Limestone.

Characteristics Of Limestone:

Colour

Limestone is a natural stone, and every slab is unique.

White, beige, and cream; Limestone countertops in lighter shades like Fine White, Rhine White, Yulan Beige, and Ivory Cream make the kitchen airy and spacious.

• Grey and Blue

These are comparatively darker shades like Azul Monica and Sino Blue, plus our Ruoms Adouci and Vert Giverny and are suited for kitchen flooring.

• Brown and Red

A Limestone countertop embedded with impurities results in shades like Poiseul, Fontenary Dore, and Chassagne Violine. With the increase in the level of impurities, they even appear rose-coloured, Hauteville C Flamme or Rose De Bourgogne B5. These earthy tones make kitchen and bathroom worktops look very elegant.

Crumbling

Limestone Countertops show some amount of brittleness. Causes could be a breakdown of the binder, the effect of external factors, or the innate fragility of the Limestone itself.

Durability

Limestone countertops and chimneys are extremely durable, but they seem to deteriorate when exposed to extreme natural effects of wind, rain, and thermal instability. It happens because Limestone, a carbonate rock, reacts highly to contact with even mildly acidic rainwater. However, kitchen worktops will be more manageable since they are indoor surfaces.

Staining

The most common types of staining agents in Limestone are rustic stains of metals, Bronze and copper stains from unattended copper salts, dyes and inks, and organic stains from tea, coffee, etc.

Chipping

Limestone countertop can be used as chopping boards must be used permanently to avoid cuts, knocks and scratches.

Heat Tolerance

Limestone countertops show great heat tolerance, which means your countertop will not be damaged upon placing a hot pan or dish directly on the countertop. However, it is advised not to leave hot and heavy objects for longer and to avoid dragging them over laminate worktops. Proper sealing of Limestone before installation as kitchen worktops and at regular intervals after being so can ensure its longevity. Upon spillage, a clean sponge or paper towel can be used to blot, followed by rinsing with hot water.

Feasibility

The benefit of limestone countertops is that they're cheaper than other natural stones like Granite or Marble.

Composition Of Limestone:

Limestone is a calcium carbonate crystal form, prevalent as aragonite or calcite. Every Limestone comprises 50% calcium carbonate at the least, by weight, significant amounts of magnesium carbonate (MgCO3), which is also known as dolomite, and negligible portions of clay, iron carbonate, siderite, sulfate, feldspar, pyrite, and quartz. Pure Limestone is exclusively white or almost it. Upon getting mixed with impurities, they exhibit a range of colours from pale to beige, yellow, grey or blue.

Finishes Of Limestone Worktops:

Polished Finish

This type of finish makes a limestone surface shiny, enhancing its quality of reflection. It is achieved by rubbing the stone's surface with increasingly fine diamond grit pads. They are best kept with a sharp edge.

Honed Finish

A honed finish is created similarly to the polished finish but with a coarser grade of grit, which makes the limestone worktop appear matte, less glossy and reflective but still smooth. For example, they are honed to a lesser grit if used in an area where it should not be slippery, like bathroom floors.

Tumbled Finish

This finish gives the Limestone countertop an aged, weathered, bleached look. This type comes with round edges. Tumbled tiles are best known to suit old, traditional looks. However, it can make modern furniture like kitchen and bathroom worktops look exquisite if handled professionally.

Brushed Finish

Brushing the stone with hard nylon or steel brushes brings this finish to life. This increases the capability of the surface to withstand scratches and marks. This brings about a slightly textured surface.

Flamed Finish

Flamed finish: to create this finish, an oxy-acetylene torch is passed over the stone surface, quickly followed by pouring cold water under pressure that leaves the top of the stone fractured. Only some quarries have this specialised technique, creating an anti-slippery surface ideal for public areas and terraces.

Bush-hammered

Bush-hammered: this look is achieved by hammering the stone with a sequence of steel points that break up the surface and create a scarred look. This is quite similar to a flamed finish and is also used in creating slip-resistant surfaces. It can be done to a greater or lesser degree based on the requirement.
