Kabini fɔlɔ, kabakurun dabɔlenw bɛ kɛ kosɛbɛ so nɔgɔmanw ni masasobaw, batosow ani fɛn wɛrɛw jɔli kama, minnu kun ye ka mɔgɔ kabakoya n’u bonya, u ka nɛɛma ani u cɛɲi ye. A ka ca a la, a bɛ fɔ ko minnu tɔgɔ bɔra kosɛbɛ u cɛma i n’a fɔ Misira piramidiw, Taj Mahal walima Köln ka katedrali. Nka hali bi, kabakurun nafama ma bɔnɛ a nafa la cogo si la jɔli la, k’a sababu kɛ a sɔrɔli ye, ka fara cɛɲi ni farikolo cogoya kɛrɛnkɛrɛnnenw kan, kabakurun nafama suguya caman bɛ minnu na.
So jɔli waati la, fɔlɔ, jateminɛ bɛ kɛ fɛn dilannen fanga kan. O farikolo-yɔrɔ in de kan, fɛn in sɛgɛnbaliya ani, o hukumu kɔnɔ, a kɛli baarakɛcogo suguya caman na, o bɛ bɔ. Fanga siratigɛ la, a ka c’a la, kabakurun nafamaw bɛ tila kuluba saba ye:
- faraw fanga ka bon (granite, quartzite ani dɔ wɛrɛw);
- fara minnu fanga ka dɔgɔn (marbre, travertine, ani dɔ wɛrɛw);
- faraw fanga dɔgɔyalen don (kalan, kuransi ani fɛn wɛrɛw grade lafiyalen).
Taamaʃyɛn wɛrɛ min bɛ nɔba bila kabakurun nafamaw ka fɛɛrɛbɔ la (misali la, a bɛ se ka polisi, a ka nɔgɔ ani a tɛ se ka asidi kɛlɛ) o ye a ka poroze ye, o kɔrɔ ye ko a kɔnɔna hakɛ ye santimɛtɛrɛ kubik kelen na. Fɛn suguya bɛɛ girinya min dilannen don ni kabakurun nafama ye, ani a bɛnnen don baarakɛcogo la ani a ka funteni-taama na, o bɛ bɔ a de la k’a ɲɛsin a ma (o cogo kelen na, ni kabakurun nafama ka porosity ka bon, taamasiyɛn minnu tɔgɔ fɔra, olu ka fisa). O nafa ka bon ka jateminɛ kɛ ni aw bɛ kɔnɔna yɔrɔw ban (misali la, ni aw bɛ duguma tasuma don ani o ɲɔgɔnnaw).
Nka poroze jiralan fana nafa ka bon ka jateminɛ kɛ ni kabakurun bɛ baara kɛ kɛnɛma baara kama, ka fara fɛn nafama suguya caman dilanni kan, i n’a fɔ jɔlanw, ɛrɛzɛnsunw, ani a ɲɔgɔnnaw. Tiɲɛ ye ko ni kabakurun in ji minɛni ka ca, a ka se ka nɛnɛ kunbɛn, o bɛ dɔgɔya, bawo ji min sumana, i n’a fɔ aw b’a dɔn cogo min na, o bɛ teli ka bonya, ka kabakurun jɔcogo tiɲɛ o cogo la.
Taamaʃyɛn nafama dɔ ye kabakurun nafamaw ka sɛgɛnbaliya ye, o nafa ka bon kɛrɛnkɛrɛnnenya la yɔrɔw la minnu bɛ to ka ɲɔgɔnkanuba sɔrɔ walima ka degun wɛrɛw sɔrɔ (misali la, ɛrɛzɛnsunw, dugumalanw, a ɲɔgɔnnaw). O taamasiyɛn kelen bɛ se ka kɛ kabakurun in ka se ka sigida fɛn suguya caman kɛlɛ, i n’a fɔ kɔgɔ walima asidi. O ka kan ka jateminɛ kɛrɛnkɛrɛnnenya la ni sow jɔli ye minnu dilannen don ni kabakurun nafamaw ye duguw kɔnɔ minnu fiɲɛ falen don u la tiɲɛ na.
Nka ka fara farikolo ta kan, kabakurun nafama fana nafa ka bon, minnu bɛ sow jɔlenw cogoya jira walima minnu bɛ lamini n’a ye. Olu dɔw ye, fɔlɔ, kabakurun dabɔcogo bɛnnen ye ka ɲɛsin sɔgɔli ma, ka fara a masirili nɔ kan, n’o ye taamasiyɛn ye min bɛ mɔgɔ yɛrɛ kɔnɔ dɔɔnin, i n’a fɔ kabakurun nafama suguya caman, a kɛcogo ani a jogo wɛrɛw. Ka bɔ polishability (polishability) la, o bɛ bɔ tigitigi ni kabakurun bɛna a ka yeelen ni a cogoya min bɛ mɔgɔ ɲɛnajɛ, o mara.
