Lithupa tsa makenete li sebelisoa haholo ho sefa lithakhisa tsa tšepe ka thepa e tala;Sefa mefuta eohle ea phofo e ntle le mokelikeli, litšila tsa tšepe ka har'a metsi le lintho tse ling tsa makenete.Hona joale, e sebelisoa haholo indastering ea lik'hemik'hale, lijo, ho tsosolosa litšila, carbon black le masimo a mang.
