I revisited for her my impatience, learning to wait for the slab-rolled clay to be in the perfect zone of hardness so as to prevent the intended geometrical shapes from deforming as I cut through the clay with a knife; learning to glaze the top surface of all those rows and rows of micro-tiles three times each with a tiny brush without them tipping over and fusing together in the glaze kiln; hand-mixing many 60 pound bags of mortar; mortar burning my finger-tips as I delicately placed each micro-tile into its precise place in the mortar bed

Pointing is the outer face of the mortar bed
