1.Granite thiab Marble: Cov yam ntxwv tsom xam ntawm ob hom Tombstone pob zeb
Granite yog lub pob zeb uas tsis muaj zog uas tsim los ntawm quartz, feldspar, thiab mica nyob rau hauv qhov kub thiab txias. Its quality is extremely dense and hard (Mohs hardness 6-7), with extremely low water absorption and excellent acid rain and frost resistance. Qhov no tso cai rau granite tombstones tuaj yeem tiv taus ntau pua xyoo ntawm cua thiab te nyob rau hauv qhov chaw sab nraum zoov uas yuav luag tsis muaj huab cua, thiab cov ntawv thiab cov qauv carved los ntawm sandblasting tuaj yeem ua kom pom tseeb thiab ntse txawm tias tsis muaj kev saib xyuas. Nyob rau tib lub sijhawm, granite muaj ntau yam xim, xws li classic dub thiab grey rau cov suab tshwj xeeb xws li liab, ntsuab, thiab xiav.

Marble yog lub pob zeb metamorphic tsim los ntawm recrystallization ntawm limestone nyob rau hauv qhov kub thiab txias, nrog calcium carbonate ua lub ntsiab tivthaiv. Nws qhov kev ntxhib los mos yog mos (Mohs hardness 3-5), tab sis nws muaj huab cua ntws zoo li kev ntxhib los mos thiab cov pob tshab zoo nkauj, uas tuaj yeem nthuav tawm cov duab zoo nkauj heev, tshwj xeeb tshaj yog tsim rau carving tiag tiag portraits lossis complex toj roob hauv pes. Txawm li cas los xij, qhov tsis muaj zog ntawm marble yog nws cov huab cua tsis zoo - nws yooj yim eroded los ntawm acid nag, muaj kuab paug, thiab txawm acidic tshuaj nyob rau hauv cov noog poob, ua rau nto hmoov, tev, thiab qhov muag plooj. Qhov no tshwj xeeb tshaj yog tshwm sim nyob rau hauv cov av noo, los nag, los yog ib puag ncig muaj kuab heev, thiab yuav tsum muaj kev saib xyuas tsis tu ncua kom ncua nws txoj sia.

Cias muab, granite paub txog nws "lub zog nyob mus ib txhis" thiab yog qhov kev xaiv ua tau zoo rau qhov ntev -ntev tso rau sab nraum zoov; Marble paub txog nws "kev kos duab zoo nkauj" thiab tsim nyog rau kev ua koob tsheej nco txog uas yuav tsum muaj kev tiv thaiv ib puag ncig lossis saib xyuas cov ntsiab lus carving.
2.Cemetery kev tso kawm: Yuav ua li cas xaiv qhov zoo ntawm granite thiab marble?
Thaum xaiv cov ntaub ntawv tombstone rau cov neeg hlub, qhov tseem ceeb ntawm kev txiav txim siab tsis yog "qhov twg zoo nkauj dua", tab sis "qhov twg tuaj yeem ua tau zoo dua qhov kev ntsuam xyuas ib puag ncig ntawm lub toj ntxas".
Feem ntau ntawm cov toj ntxas nyob sab nraum zoov - raug tshav ntuj, nag, Frost, kua qaub los nag, plua plav, noog poob... Cov ntsiab lus no txiav txim siab tias granite yog qhov ruaj ntseg thiab ntev ntev - xaiv. Nws ultra- tus nqi nqus dej tsawg thiab cov kua qaub tiv thaiv kom ntseeg tau tias cov ntawv tseem nyob ruaj khov thiab cov monument tseem nyob tom qab ib puas xyoo, yuav luag tsis tas yuav tsum muaj kev saib xyuas ntxiv. Tshwj xeeb tshaj yog nyob rau sab hnub tuaj thiab yav qab teb Tuam Tshoj, nrog rau nyob ib ncig ntawm lub nroog muaj kev lag luam, cov kua qaub los nag thiab cov av noo ib puag ncig tuaj yeem ua kom lub zog degradation ntawm marble, thaum granite yuav luag tsis cuam tshuam.
Yog hais tias lub toj ntxas koj xaiv nyob rau hauv ib lub tsev crematorium, lub qhov ntxa tsev, los yog nyob rau hauv ib tug qhuav thiab rainless cheeb tsam txhua xyoo puag ncig (xws li cov arid qaum teb sab hnub poob cheeb tsam), thiab koj muaj nuj nqis rau lub cim ntuj zoo nkauj ntawm marble thiab cov artistic nyhuv ntawm carving tiag tiag portraits, ces marble yuav siv tau los ua lwm txoj. Tab sis nws yog ib qho tsim nyog yuav tsum tau npaj siab ua ntej: marble yuav xav tau kev sib khi, polishing, thiab lwm yam kev tu txhua txhua 1-3 xyoos nyob rau hauv ib puag ncig sab nraum zoov, txwv tsis pub cov nto yuav ua rau hmoov, yellowing, los yog qhov muag tsis pom kev.
