THE MOULD IN THE BOWL

The occupant set the box down under the porch, in the stretch where the shade had already retreated a hand's width. Renan knelt in front of it and took from his pocket a folding measuring blade, linked to the workshop for eleven shifts. The instrument recognised his fingerprint, opened three segments and projected onto the pale alloy the accepted limit for the rib. Twenty-six minutes remained. Don't touch the part, said Renan. Are you going to take it on, asked the man. I'm going to measure the error without accepting their measurement. The lid followed his hands with two tracking cameras. Renan turned the box until one of them caught the sun. The image lost contrast, corrected the exposure and found his fingers again. He fitted the blade into the side groove. The tip went in four millimetres and stopped. The workshop accepted a difference of less than one. The shaft exceeded the tolerance by three, but the panel showed adjustment possible by means of technical pressure. Technical pressure meant pushing the alloy until the rotor gave first. Then the damage would have a human name. Ilva brought a strip taken from the packaging of the plates delivered to the bar. The flexible compound had been made to immobilise cargo during transport and kept parallel creases. Renan refused with a shake of his head. He needed a material that would take the shape without springing back. There's dough in the kitchen, said Luzia. The girl appeared with a small portion of cold porridge on a spoon. Renan squeezed the paste between two pieces of the compound, forming a plate the width of his hand. The heat softened the mixture. Farinha and water, already charged to the house, became a workshop instrument. He covered the rib with a film used for keeping food and pressed the plate against the shaft. The porridge gave at the edges, rose into the groove and reproduced the excess. Renan held the pressure for forty seconds. His purple forearm began to tremble at twenty-three. At thirty, sweat fell from his chin onto the earth. He kept on until Luzia finished a count of fifty-two. You can take it off, she said. Not yet. When he drew the plate away, the mould brought out one deep line and another almost erased. The second revealed that the rib had been machined off centre. Renan measured three times. The first reading gave two millimetres and eight tenths. The second, three and one. On the third, he shifted the blade's support, held his breath and found exactly three. The panel rejected the mould for being of food origin. Ilva put her bandaged hand near the box, without touching. Do the reading by the shadow. Renan held the plate up against the sodium light still lit under the porch. The blade projected lines over the relief. Where the paste thickened, the shadow advanced. He marked the two limits with small cuts in the transport compound, without harming the mould. The camera recognised the cuts, compared the distance and opened a classification the workshop had not offered before. Reproducible dimensional divergence. Eleven minutes were left. The supply manager appeared on the panel only as a voice. The mould is not part of a certified tool, she said. The refusal maintains the residential audit. Renan ran his tongue over his dry lips. Since he was a boy, before the mine covered the field behind the bar, he had trued cart wheels with blades cut from cans and wet clay. At the workshop, he had learned to hide that knowledge under names bought by the consortium. Now the word certified was trying to take from his hand a measurement the hand had just produced. He split the compound into two halves. One kept the negative of the rib. Into the other he pressed the blade to the authorised depth. He placed the two side by side before the camera. The difference raised a thin edge, visible even when the projection was removed. Classify it as a fit comparison, he said. Your profile does not hold metrological authorisation. My profile received the shipment. The answer kept the manager silent for six seconds. Each second consumed the deadline without altering the part. The occupant opened the household panel. The second audio appeared as a provenance alternative. He covered the offer with his palm, but did not authorise the playback. Renan selected provisional custody. The lid asked for bodily confirmation. He touched two fingers to the light strip and accepted the part for one hour, linked only to the dimensional verification. The workshop withdrew the immediate audit of the house, kept the pay suspended and added a condition. The mould had to reach the booth intact before the end of the custody. If it dried out or broke, the refusal would be converted into handling damage. The paste was already paling at the edges. Ilva fetched the nearly empty metal bowl. Renan put in no water. He lined the bottom with dry pequi leaves, rested the mould on them and closed the bowl with the rest of the flexible compound. The trapped air would slow the loss of moisture for less than an hour. The tool remained linked to his body. The box stayed under the house's responsibility until the proof was delivered. Renan stood up slowly, his legs numb and his shirt heavy with sweat. He handed the box to the occupant, took the bowl between both hands and went down the porch steps alone.
