Black rakuware tea bowl (late sixteenth century), Kyoto, Japan. Freer Sackler Museum of Asian Art.
For Irwin, the lesson of [the raku tea cups] was twofold: first, their presentation was important, insofar as the ceremony involved a gradual preparation of the audience’s aesthetic attention. Then, when the time came to handle the cups, the intimacy of the experience fused visual and tactile sensations into a single continuum. As he also noted:
he would set on the table this box with a beautiful little tie on it – very Japanese – and you untied it, you opened up the box, he let you do that. And then inside of it was a cloth sack. You took the sack out, and it had a drawstring, and you opened up the drawstring and you reached inside and took out the bowl. By that time, the bowl had you at a level where the most incidental detail – maybe even just a thumb mark – registered as a powerful statement.
Most Japanese bells when hung still have on them one or more rough lines obviously arising in horizontal mold joints. These lines are not removed in fettling the bell, and they seem to be regarded not as defects but rather as a reminder of the reality of the founder’s interaction with his materials. One is reminded of the ceramics that are most treasured in Japan which usually have some unexpected tool marks or irregularity resulting from a kiln mishap.
Roughness is the odd shape, the quick brush stroke, the irregular column size or spacing, the change in pattern at the corner – it is adjusting to conditions as they present themselves with meaning, but without ego or contrived deliberation.
Though it may look superficially flawed, especially with human perception accustomed to mass-produced regularity and perfection as a goal, an object with roughness is often more precise because it comes about from paying attention to what matters most, and letting go of what matters less.
A façade of some 6,000 pure-glass blocks (50mm x 235mm x 50mm) was employed. The pure-glass blocks, with their large mass-per-unit area, effectively shut out sound and enable the creation of an open, clearly articulated garden that admits the city scenery. To realize such a façade, glass casting was employed to produce glass of extremely high transparency from borosilicate, the raw material for optical glass. The casting process was exceedingly difficult, for it required both slow cooling to remove residual stress from within the glass, and high dimensional accuracy. Even then, however, the glass retained micro-level surface asperities, but we actively welcomed this effect, for it would produce unexpected optical illusions in the interior space.
We love to see the process, not just the result. The imperfections in your work can be beautiful if they show your struggle for perfection, not a lack of care.
