Wood petrification ndi mwala wapadera wamtengo wapatali, womwe umadziwikanso kuti petrification, womwe umatanthawuza kusinthika kwapang'onopang'ono kwa nkhuni kukhala miyala yamwala panthawi ya geological process. Mwala wamtunduwu nthawi zambiri umakhala ndi mawonekedwe ndi mawonekedwe amitengo, ndipo umakhalabe ndi matabwa, koma minofu yake yasinthidwa kwathunthu kapena pang'ono ndi mchere. Mitengo yamtengo wapatali imatha kudulidwa, kupukutidwa ndi kulemekezedwa kuti ipange zokongoletsera zosiyanasiyana ndi zodzikongoletsera monga zolembera, mphete ndi zibangili. Mtundu ndi kapangidwe kake zimasiyanasiyana malinga ndi mchere womwe uli nawo, koma mitundu yodziwika bwino imakhala yofiirira, yachikasu, yofiira, ndi yakuda.
Mitengo yamatabwa yamatabwa imatanthawuza chitsulo chachikulu cha agate chomwe chimapangidwa pambuyo pa ndondomeko ya lignification. Zimaphatikizapo makhalidwe a nkhuni ndi mwala wa agate, ndi mawonekedwe apadera ndi mtundu. Ma agate opangidwa ndi matabwa nthawi zambiri amagwiritsidwa ntchito pokongoletsa mkati ndi zida zomangira, ndipo amatha kugwiritsidwa ntchito popanga ma countertops, makoma, pansi, ndi zina zambiri.
Posankha slab yamatabwa, muyenera kulabadira mfundo zotsatirazi:
1. Sankhani wogulitsa mwala nthawi zonse kapena msika wogulitsa zinthu zokongoletsera kuti muwonetsetse kuti katunduyo ndi woona.
2. Samalani kuti muwone ngati mawonekedwe ndi mtundu wa matabwa a agate slabs ndi ofanana ndi achilengedwe, ndipo pewani ming'alu yoonekera, zipsera kapena kusiyana kwa mitundu.
3. Ganizirani ngati kukula ndi makulidwe a lignified agate slab ndi oyenera pulojekiti yokongoletsera yomwe mukufuna.
4. Mukayika ndikugwiritsa ntchito ma slabs a agate, m'pofunika kutsatira zomangamanga ndi kukonza zofunikira kuti zitsimikizire kuti kukongola kwake kwa nthawi yaitali ndikugwira ntchito.
Mwachidule, matabwa opangidwa ndi matabwa ndi chinthu chodziwika bwino komanso chokongola chokongoletsera, chomwe chili choyenera zokongoletsera zosiyanasiyana zamkati ndi zosowa zamapangidwe.
