Batch No.4
Rock Description= Upon collection the rocks are a shale-like, grey, with a green undertone. Undetermined impurities colour the rocks, presenting with iron-like qualities. Sedimentary rock with an undetermined rock sub-category.
Preliminary Fire Temperature= 999 C
Mill Time= 3 hours
Water Weight= 750.00g
Particulate Weight= 341.00g
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 turned to powder without much force—becoming, turning into, rubble shortly and quickly—and presented moderate iron content surfaced into warm dust on surface. The impurities at this stage, are presenting uniformly as iron-rich. The slip is a dark grey, and the particulate settles rapidly, sticking to the bottom of the container, and so, requiring agitation to maintain consistency in application and regain workability.
^5 Fire Results= There is a minor development of the colour to the particulate, changing during the preliminary fire, into a more warm-hued brown colour with a deeper saturation.
^10 Fire Results= From the results, an estimation of the silica proportion is moderate-to-high.
^5 Surface Description= At this temperature, despite seeing the particulates integration into the ceramic surface, the particulate remains without any signs of vitrification or significant change
^10 Surface Description= At this high temperature, the role of silica’s proportion is evident—playing the role of glass in the high gloss finish to the pooled areas on the surface.
ID 6:
[The surface remains unstable. Subject to anything that graces its surface, this particulate is resting on the ceramic tile’s surface. Preserved from the drying process, the fine-line-cracks in the surface, around the perimeter of the tile, occurred during the particulate application separating from itself. The colour throughout is a deep brown that blocks the ceramic surface from appearing on the square tile apart from small fragments lifting from the outermost edge of the tile.]
ID 7:
[The vitrified particulate pools gesturally across the square brown tile’s surface. Where the particulate is thin, the granularity is gray, brown, and sand, and where the particulate is thick it is a burnt-butter brown. Like a coagulation, the glassy surface leads itself around the place of the tile and meets and leaves itself across in varying ways.]
