Izvi zvichaita nechokwadi yakakwirira kunaka batira.

mamwe zvinoriumba

Kana uri kufunga sei kusanganisa kongiri ari kongiri chisanganiso, kukura makaisa pamusoro anogona kushandiswa nemi. Zvinokosha kufunga kwete chete ukama asiwo kudiwa okuwedzera zvinoriumba. Lime zvinogona kupatsanurwa pakati pavo. Pairi ichakurukurwa pazasi. Rinoshandiswa apo vaiitawo zvakanaka yepamusoro mvura mhinduro. Inofanira kuva akachena, hazvifaniri kuva inclusions muchimiro acids uye alkalis. Hazvina kunaka kushandisa musoro kana rwizi, gungwa mvura. Mvura yakakodzera yokunwa, inogona kushandiswa kugadzira kongiri.

yokuvirisa

Kana pane vanoda kuti kongiri nyore kuisira, rinogona kushandiswa kwacho kusanganiswa murwiyo kwesuko. Akariyanika chinopedza agadzirira pamwe kushandiswa kwayo, zvichava nyore kuti chechetere pemvura. Asi zvinokosha kuyeuka kuti aita madota anokwanisa kudzivirira samende pamwe filler, riri huri nziyo, izvo zvinogona yekudyidzana kukanganisa simba.
