Volcanic rock Pumice (inowanzozivikanwa se pumice kana porous basalt) imhando yezvinhu zvinoshanda zvekuchengetedza nharaunda. Iri ibwe rakakosha kwazvo rinogadzirwa negirazi rinoputika, zvicherwa nemabhuru mushure mekuputika kwegomo. Ibwe rinoputika rine akawanda emamineral uye anoteedzera zvinhu, senge sodium, magnesium, aluminium, silicon, calcium, titanium, manganese, iron, nickel, cobalt uye molybdenum. Iyo ine infrared magnetic wave isina radiation, Mushure mezviuru zvemakore, vanhu vakawana kukosha kwayo zvakanyanya. Ikozvino yakawedzerwa kuminda yekuvaka, kuchengetedza mvura, kukuya, firita zvinhu, barbeque marasha, gadheni kugadzirisa, kurima kusina ivhu, zvigadzirwa zvekushongedza nezvimwewo. Iyo inotamba isingadzoreke basa mune ese mafambiro ehupenyu! Hot dombo kubheka kumashure imhando yekurapa kwematombo, iyo inoshandisa kupisa kwemakomo anoputika kutora simba rakaipa remuviri wemunhu, kubatsira muviri wemunhu kubvisa chepfu nekusimudzira metabolism yemunhu.
