Rock Description= Upon collection the rocks are a warm 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= 8 hours
Water Weight= 1250.00g
Particulate Weight= 231.00g
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 red-brown, and the particulate settles rapidly, and so, requiring agitation to maintain consistency in application and regain workability. The water that settles on the surface takes on a significant amount of the impurities, meaning, the water is yellowed by the specific impurities in the particulate.
^5 Fire Results= The particulate is a darkly muted pink colour. Evidence of the way the particulate pooled upon absorption is retained.
^10 Fire Results= The colour shifted, and paled, to a yellow-brown hue leaving the muted pink entirely. From the results, an estimation of the silica proportion high is which also caused the purge to the raised surfaces.
^5 Surface Description= At this temperature, despite seeing the particulates integration into the ceramic surface, the particulate remains without signs of vitrification and pools only slightly.
^10 Surface Description= At this high temperature the particulate is vitrified, and the former pools have fired out into black grains/distinct particulates from the remainder of the glossy surface.
[The surface is stable but its porosity is intact. On the surface, the particulate is hazed over the entirety of the ceramic tile. Throughout the square tile, the dulled mauve colour presents itself, remaining chalky and penetrable; the particulate is irregular in a manner that is pictorially atmospheric.]
[The vitrified surface is high-shine. On the lower hemisphere, there are two twinned circles where air pocketed during the particulate’s application onto the surface. In a muted tone, the particulate is yellow. The semi-transparency of the particulate reveals select details of the below ceramic tile surface. Although the particulate is glossy, the granular aspects remain present.]
