Process & Production
According to the recipe instructions, the vitreous binder (lead-silica glass) was prepared first and consisted of (Pb3O4·SiO2 5:2 wt) following the recipe of Fondant 2 by Bontemps (1868) (Pb3O4·SiO2, 5:2 by wt).Then natural haematite (Fe2O3) and the lead-silica glass were mixed in the proportion of 2:7 by wt and ground together. Finally, the powder was painted on a glass with turpentine as specified in the recipe, and the paint was fired at 620ºC for 30 minutes (ramp 3ºC/minute).
