Karakteristik Kromatik Bone Ash Sintetik Berdasarkan Suhu Kalsinasi

Herlina Damayanti, Ayu Ratnasari, Kristanto Wahyudi

Abstract


Pada penelitian ini sifat kromatik bone ash sintetik telah dipelajari berdasarkan sistem CIELAB. Bone ash sintetik dikalsinasi dengan variasi suhu 600oC – 1250oC. Masing-masing hasil kalsinasi dijadikan aplikasi glasir ubin pada suhu 1170oC. Panjang gelombang bone ash sintetik kalsinasi 492-574nm dan glasir bone ash 477-542nm, berarti termasuk material putih. Derajat whiteness dan brightness mengalami penurunan dengan nilai terbesar pada bone ash kalsinasi 1250oC, Dwhiteness = -59,90% dan Dbrightness = -61,42%. Berdasarkan nilai L*, a* dan b* ruang warna bone ash sintetik bergeser dari Hijau Kuning menjadi Hijau Biru dan indeks whiteness bergeser menuju hitam. Pergeseran warna terkecil adalah bone ash kalsinasi 1000oC, ΔE  = 13,37 dan terbesar adalah bone ash kalsinasi 1250oC , ΔE  = 37,75. Pergeseran indeks whiteness terkecil adalah bone ash B10, ΔW* = 13,20 dan terbesar adalah bone ash B125  ΔW* = 36,29.
