1: INFRASTRUCTURE
To facilitate of holding and malleability of the powder of quartz which is 78-85 % of the mixture, fusing/melting glass is added. The tile slabs which is shaped by hand in wooden moulds is left to natural drying for 20-25 days, then they are retouched and undercoated/underglazed. |
EMERING
The tiles plaque which are dry
subjected to process of emering
for measuring. |

2: UNDERCOAT/UNDERGLAZE (ANGOP)
It is a mixture whose composition is near the composition of the clay it covers, only it is tiny and fired as white.
The fluid underglaze is poured over and covers the dry slabs. After leaving to dry for seven days, slabs are carefully fired (bisque firing). |

3: ORNAMENTATION (DESIGN AND PAINTING)
After transferring the prepared designs as templates on the bisque slabs, these designs is drawn and painted on with metal oxide and other pigments which can be applied on the underglaze and keep the colours under the glaze; composition of the paints used for tiles reflex the colours of precious stones on being formulated as the closest to the original one to preserve its vividness. |
