Batch No.7
Rock Description= Upon collection the rocks are red-brown, with entirely warm undertones. Undetermined impurities colour the rocks, presenting with iron-rich qualities. Sedimentary rock with an undetermined rock sub-category.
Preliminary Fire Temperature= 955 C
Mill Time= 6 hours
Water Weight= 750.00g
Particulate Weight= 235.00g
Post-mill Protocol= 100 mesh, after sieve removed a significant amount of water leaving the slip thicker.
Material Behaviours= Following the ^06 preliminary firing, the particulate’s moderate iron content surfaced into warm dust on the surface and appears to have altered the rock to the core. The impurities at this stage, are presenting uniformly as iron-rich. The slip is a brown colour, and the particulate settles quickly, sticking slightly to the bottom of the container, and so, requiring agitation to maintain consistency in application and regain workability.
^5 Fire Results= From the results, an estimation of the silica proportion is low and undetermined. There is no evidence of vitrification at this temperature.
^5 Surface Description= At this temperature, the surface is carrying a consistent colour of faded pink. The particulate is integrated into the tile and it remains dry.
ID 12:
[The surface remains unstable. Presenting as underdeveloped, a light pink particulate dusts the surface of the tile. Uneven with irregularities in both distribution and consistency, the surface is presented with its two imbricated facets, one ceramic, and the other material ready to leave the picture plane. The particulate is pulled back around the edges of the square tile and more so in the upper lefthand corner, this exposes the raw ceramic.]
