Abstract
Telah dilakukan kajian pengaruh penambahan kobalt dan titanium oksida terhadap warna glasir porselen ZnO yang bertujuan untuk menentukan pengaruh jenis dan konsentrasi oksida logam terhadap warna glasir keramik porselen dengan prinsip pergantian atom pada sisi kristal sehingga menghasilkan warna. Metode yang digunakan dalam percobaan ini adalah pembakaran dan spray. Sampel yang diuji adalah glasir kobalt oksida dan titanium dioksida. Berdasarkan percobaan diketahui bahwa oksida logam yang berbeda akan menghasilkan warna glasir yang berbeda pula. Semakin besar konsentrasi oksida logam yang ditambahkan maka warna glasir yang diperoleh juga semakin gelap atau jelas.
Keywords
