| Translucency of unglazed bone-china pieces of thickness 1-2 mm,
fired at different temperatures, was measured. It was found that
samples fired at temperatures less than 1150°C showed hardly any
translucency for a reasonable soaking time. Thickness of samples
was less critical than the firing temperatures. A firing temperature
of 1200° to 1250°C with one and half hours to two and half hours
soaking time resulted in translucency of unglazed bone-china samples
which compared favourably with commercial samples. |
