Gawo la njerwa zowala, mattenjerwa ndi njerwa zofewa zowonetsedwa m'masitolo amtundu wina ndizofanana, pomwemasitolo ena amtundu amasonyeza njerwa zowalakwenikweni, zomwe njerwa zowala mu sitolo ya mtunduwu zimawerengera pafupifupi 90%. Woyang'anira zogula adanena kuti panali mitundu itatu yokha ya njerwa zofewa zofewa m'sitolo yake posachedwa, ndipo chiwonetsero chachikulu chinali njerwa zowala.njerwa kapena njerwa zofewa.
Ndi kuchuluka kwa mattematailosi ndi matailosi ofewa, mabizinesi ambiri a ceramic asungabe malingaliro awo,chifukwa amamvetsetsa kuti kulimbikitsa mwamphamvu mitundu iwiriyi ya zinthu zosalala malinga ndi kusowa kwawo kwa chinthu china ndi maziko a tchanelo kudzakhala ndi zotsatira zoyipa pa mbiri yamtundu. Akatswiri enaadanena kuti kapangidwe kazinthu zamabizinesi zimakhudzana kwambiri ndi kayimidwe kake komanso kayimidwe kamagulu ogula. Ngati chizindikirocho chikuyang'ana pa msika wotsika kwambiri ndi njira zamakono, omvera angakonde njerwa zowala; Ngati mtunduwo umayang'ana kwambiri ogula achichepere ndi njira zopangira, omvera angakonde mattenjerwa ndi njerwa zofewa.
Ndizofunikira kudziwa kuti ngakhale njerwa zamitundu yowoneka bwino ndizodziwika bwino pamsika, matailosi amtundu wa marble akadali ofala kwambirimasitolo ogulitsa.
