Guusha ama guuldarada saamaynta dhammayn dildilaaca waxay si aad ah ugu xidhan tahay isuduwidda isuduwidda cabbirrada codsiga. Goobaha dayactirka guryaha, fiiro gaar ah waa in la siiyaa saddexda dhibcood ee soo socda: Substrate-ka-daawaynta ka hor waa lama huraan: Dabaqyada birta ah waa inay maraan hoos-u-dhigid, ciid, iyo bakhti, oo ay ku xigto codsiga birta khaaska ah. Tijaabooyinku waxay muujiyeen in habkani uu kor u qaadayo xabagta in ka badan 300%, taasoo lagu gaadhay qiimaynta ugu saraysa—ASTM 5B — ee imtixaanada xabagta iskutallaabta ah. Xakamaynta saxda ah ee Dhumucda lakabka Rinjiga ee dillaacsan: Marka uu dhumuc weyn yahay filimka rinjiga, ayaa sii ballaaranaya dildilaaca ka dhasha. Codsiyada deegaanka, dhumucda filimka qalalan ee 30-50 μm ayaa lagula talinayaa. Midabka Koowaad wuxuu go'aamiyaa bilicda kama dambaysta ah: dildilaacadu waxay daaha ka qaadi doonaan midabka lakabka hore ee hoose. Waxaa lagu talinayaa in la doorto muraayad sare oo iftiin-sare ah, oo aan huruud lahayn oo biyo ku salaysan (sida taxanaha "Wuqiongua") si loo gaaro saamaynta caadiga ah ee isbarbardhigga ee "dillaacyada cadaanka ah ee ka sarreeya Primer mugdi madow." Gabagabo/Talo soo jeedin biraha rinji rinji leh ee jeexjeexan ayaa u bislaaday qaab dhismeed gudaha ah oo heer sare ah, oo inta badan loo isticmaalo darbiyada sifaha leh, albaabbada qurxinta, iyo qaybiyayaasha qolka farshaxanka. Qiimahooda udub-dhexaadku wuxuu ku jiraa bixinta xal "laba-saamayn" ah: waxay bixiyaan farshaxan farshaxan oo gaar ah, oo aan la soo koobi karin iyagoo isla mar ahaantaana ka faa'iideysanaya substrate-ka birta si ay u bixiyaan sifooyin jireed oo heer sare ah - gaar ahaan caabbinta dabka, iska caabinta qoyaanka,
