NIKI Kibuye CYIZA CYANE KANDI BASHOBORA GUKORESHWA? ibuye

Kuki bamwe amabuye asanzwe considered to be soft when they all appear to be hard? The answer lies within ‘relative’ hardness. Mohs scale of hardness was invented in 1812 and compares the relative hardness of ten minerals. Diamond is the hardest and rates a 10, while granite is the toughest natural stone at 6. Limestone comes in at 3 as does its metamorphic counterpart, marble. Softer stone is easier to dress or carve but does not wear or weather quite as well as harder stone. Here we discuss some of the more popular soft stones along with suitable applications.

Amabuye adasanzwe

Urutare

Amabuye, amabuye yumucanga na shale nubwoko bukunze kwibutare bwimitsi. Ibi byakozwe binyuze mu muvuduko mwinshi, mu myaka miriyoni, bitwaje imyanda yaguye hasi yinyanja.

The layers in slate are described as being “foliated” and they are easily split apart to create whatever thickness is required. UK slate is considered to be hard and was traditionally used as roofing, while soft slate is found in China, Spain, Italy and the USA. With a broad range of natural slate colours, a multiple array of designs can be achieved, from contemporary to classic, rustic to refined. Slate is often recommended for high traffic areas, thanks to its remarkably durable composition. It is also non-porous and does not easily react with acid liquids. It is fire proof, weather resistant and achieves good slip resistance dues to its riven finish.

Limestone is a very common building material and is formed mainly from the mineral calcite, derived from the calcium in bones and seashells deposited over the millennia and forced together through pressure. While it also contains magnesium, it is harder and more weather resistant, and can also be polished. Portland stone from the eponymous island in Dorset is probably the single most famous type of limestone and was used to build many of London’s great buildings. It is used for external cladding as well as paving, fireplaces and other internal and external decorative features. Its soft colours are its trademark visual attributes.

Umusenyi

Sandstone birashoboka ko aribwo bwakoreshwaga cyane mu kubaka mbere ya 1800, kubintu byose kuva ibiraro kugeza ku nyubako nziza. Nkuko bishobora kugereranywa nizina ryayo, ikorwa mugihe umucanga, ibintu kama, calcite nandi mabuye y'agaciro atandukanye byahujwe hamwe nigitutu kidasanzwe mumyaka igihumbi. Kuboneka hamwe nuburyo bubi cyangwa bwiza kandi busanzwe butangwa mumatiku. Ahanini cream, umutuku cyangwa imvi mubwongereza, ibara ryayo riterwa namabuye yinyongera arimo. Silica itanga umweru, mugihe icyuma kizatanga ibara ry'umutuku-umukara. Ahantu h'ingenzi ho gukoreshwa ni inkuta hasi, cyangwa pave yo hanze.

Marble

Marble ni inkomoko ya hekeste, ikorwa binyuze muri metamorphose yubushyuhe bukabije nigitutu mumyaka miriyoni. Nubwo byoroshye ugereranije nandi mabuye, marble ikunda guhanagura neza bidasanzwe. Ubusanzwe marble ikoreshwa mumiryango kandi ifasha kurema urwego rwohejuru.
