Alloy

Bronze was not a metal but a marriage.

It was an alloy, a union of copper and tin in proportions that varied depending on the purpose — bell bronze was roughly eighty percent copper and twenty percent tin, which gave it the resonance that made bells ring; gun bronze was eighty-eight percent copper and eight percent tin with four percent zinc, which gave it the hardness that made it suitable for things designed to destroy; and art bronze, the bronze that Oren worked with, the bronze that sculptors had been casting since the Benin bronzes and the Greek bronzes and the Chinese ritual vessels of the Shang dynasty, was silicon bronze, which was ninety-six percent copper and four percent silicon with trace amounts of manganese and iron, and this particular marriage of elements produced a metal that was strong and corrosion-resistant and that accepted patina with a willingness that other alloys did not, the silicon in the mix creating a surface chemistry that was, from a patinator's perspective, ideal — reactive enough to take the chemicals, stable enough to hold them.

Oren had been thinking about alloys since Tuesday.

The thought had started at the quarry, when Giuseppe had talked about raw materials and surfaces and the things that things were made of, and it had continued through the evening and into the morning and now, on Wednesday, the day of the pour, it was the thought that occupied him as he drove the Fiat Panda to Fonderia Mariani with Lina in the passenger seat and the morning sun turning the marble mountains from grey to gold.

The thought was this: that every durable thing was an alloy, a combination of unlike elements that together produced something none of them could produce alone, and that a marriage was an alloy, specifically his marriage, the union of an Icelandic man and a Norwegian woman in an Italian town, the combination of his patience and her directness, his surfaces and her interiors, his way of saying things through objects and her way of saying things through actions, and that this alloy had been formulated over twenty-six years of adjustments — more of this, less of that, a trace element of compromise here, a percentage of stubbornness there — and that the alloy was strong, was tested, was proven, and that the question now was whether the alloy could withstand the heat that was being applied to it, the two thousand degrees of the disease that was melting the wax of their previous life and that would either fill the void with something durable or crack the shell.

He did not say any of this to Lina.

He drove and she sat beside him and the road unwound and the morning was clear and warm and the autostrada traffic was light because it was early, not yet seven-thirty, and the trucks that would later fill the road were still being loaded at the quarries and the ports and the factories, and the Fiat Panda had the road nearly to itself, the little blue car carrying two people toward a foundry where a hollow ceramic shell waited to be filled with metal that was already being heated in a crucible, the copper and the silicon meeting in the fire, combining, becoming something that neither of them had been alone.

Lina had not slept well.

She had not said this but Oren knew because he had been awake too, lying beside her in the dark, listening to the new hoarseness in her breathing and to the other new thing, the restlessness, the small movements in the bed that were not the movements of a person dreaming but the movements of a person fighting, wrestling with something in the dark that had no name and no form but that was there, in the bed with them, a third presence that had entered the marriage with the diagnosis and that would not leave.

In the morning she had risen at six and taken a long shower and dressed carefully — not in the blue dress this time but in practical clothes, trousers and a cotton shirt and flat shoes, the clothes of a woman who was going to a foundry and who understood that a foundry was a place of dirt and heat and metal and that the appropriate surface was not elegance but readiness.

She had eaten only toast.

This was another change. Lina's breakfasts had always been substantial — yogurt and fruit and bread and cheese and coffee, the Norwegian breakfast adapted to Italian ingredients — and the reduction to toast was a reduction that the chemotherapy had effected, the drugs altering her appetite the way a chemical altered the color of bronze, gradually, from the inside out, and Oren had watched her eat the toast and had not commented because commenting would have been drawing attention to the change and drawing attention to the change would have been acknowledging the disease and acknowledging the disease before seven in the morning was more than either of them could bear.

They arrived at Fonderia Mariani at seven-forty.

The foundry was already active. Roberto was at the furnace, checking the temperature of the crucible, and Marco was laying out the pouring shanks — the long steel handles that attached to the crucible and that four men would use to lift and pour the molten bronze — and Giuseppe was at the shell, which had been taken from the kiln and placed upright on a bed of sand in the pouring pit, the pouring cup at the top, the shell still warm from the kiln's residual heat, and the shell looked, in the dim light of the foundry, like a small white pillar, a column of ceramic that held inside it the void that had been, ten days ago, the wax that had been, before that, the idea that had been, before that, nothing, a potential, a commission from a woman in Rome whose mother had died in a garden.

Lina stood at the edge of the pouring pit and looked at the shell.

She said, It is smaller than I expected.

Oren said, It will look larger when the shell is removed. The shell adds thickness.

She said, What is inside it now.

He said, Nothing. Air. The shape of the wax.

She said, The shape but not the wax.

He said, The shape but not the wax.

She considered this and then she nodded, once, the single nod that was her way of acknowledging a fact that she found both interesting and important, and Oren thought that this exchange — the shape but not the wax — was the most concise description of what the lost-wax process was and what it meant and that Lina had understood it instantly in the way that she understood most things, not by studying them but by apprehending them, by grasping the essence through the surface.

Roberto came over and said the crucible would be ready in thirty minutes.

The crucible was a cylinder of silicon carbide, a material that could withstand the temperatures required to melt bronze — twenty-one hundred degrees Fahrenheit, slightly higher than the pouring temperature to account for heat loss during the pour — and it sat in the furnace like a glowing orange tooth, the bronze inside it already liquid, already molten, already the alloy, the copper and the silicon having merged in the fire into a substance that was, at this temperature, as fluid as water and as bright as the sun and as dangerous as anything that the controlled environment of a foundry could contain.

Oren put on his protective gear.

The gear consisted of a face shield, leather gauntlets that reached his elbows, a leather apron, and steel-toed boots, and this was the armor of the bronze caster, the surface that protected the body from the metal, and every piece of it was scarred and stained and worn in the way that all working gear was scarred and stained and worn, the leather darkened by heat and splattered with bronze, the face shield scratched and clouded, the boots pocked with tiny burn marks where droplets of metal had landed, and this wear was the gear's own patina, the record of the pours it had survived.

Giuseppe and Marco and a fourth man — Tomasso, a young apprentice who had been at the foundry for two years and who still flinched at the heat of the pour, which was normal, which was the body's correct response to two thousand degrees — took their positions at the shanks.

Roberto gave the signal.

The crucible was lifted from the furnace with the overhead crane, a slow vertical ascent that brought the glowing cylinder up through the smoke and the heat shimmer and into the open air of the foundry, and the light from the molten bronze inside the crucible was so intense that it cast shadows, the orange glow falling on the walls and the floor and the faces of the men like a second sun, a sun that had been pulled from the ground rather than the sky, and Oren looked at Lina and the orange light was on her face and she was watching the crucible with an expression he had not seen before, an expression of attention so complete that it was indistinguishable from reverence.

The crucible was lowered onto the pouring shanks.

The four men took the weight — it was not heavy, perhaps fifty pounds of metal plus the weight of the crucible itself, but the heat radiated from it in waves that made the air above it ripple and distort, and the men held the shanks at arm's length and walked the crucible to the pouring pit in the careful synchronized shuffle of foundry workers who know that the distance between them and catastrophe is measured in inches.

Oren positioned himself beside the shell.

He would guide the pour, watching the bronze as it entered the pouring cup and flowed down through the sprue system and into the void, and his job was to keep the flow steady and to watch for problems — a blockage in a sprue, an overflow of the pouring cup, a crack in the shell that would allow the bronze to escape — and to call corrections to the men on the shanks.

Roberto said, Pour.

The crucible tipped.

The bronze came out in a stream the color of liquid light, a bright orange-white ribbon that flowed from the lip of the crucible into the pouring cup of the shell with a sound that was nothing like what people expected — not a splash or a hiss but a low continuous roar, like the sound of a fire in a fireplace amplified a hundred times, the sound of extreme heat meeting air, and the bronze filled the pouring cup and descended into the sprue system and the shell began to glow from within, the heat of the bronze radiating through the ceramic walls like light through a lampshade, and Oren watched the cup and called, Steady, steady, keep it coming, and the men on the shanks tilted the crucible further and the stream of bronze continued, a controlled river of metal flowing from the vessel of the crucible into the vessel of the shell, from one container to another, from the temporary to the permanent.

The pour took forty seconds.

In forty seconds the void that had been the memorial sculpture — the void that the wax had defined and the burnout had created and that had existed for three days as an empty space inside a ceramic shell — was filled with two thousand degrees of molten bronze, and the bronze began immediately to cool, the bright orange dimming to a darker orange and then to red and then to a dull red-black as the metal surrendered its heat to the shell and the shell surrendered its heat to the sand and the sand surrendered its heat to the air and the air carried it up and out through the ventilation hood and into the sky above Pietrasanta where it dissipated and was gone.

Lina was still watching.

The glow faded and the shell sat in the sand and the bronze inside it was cooling and contracting and solidifying, the liquid becoming solid, the potential becoming actual, and the process was irreversible, the bronze could not be uncast, could not be returned to the crucible, could not be separated back into its component elements of copper and silicon, any more than a marriage could be separated back into the two people who had entered it, because the alloy was the alloy, the combination had been made, the heat had done its work.

Oren removed his face shield and walked to Lina.

She said, It was beautiful.

He said, Yes.

She said, It looked like the inside of something. Like seeing the inside of the sun.

He said, The temperature is about a third of the sun's surface.

She said, Don't be a scientist. It looked like the inside of the sun.

And he accepted this correction, this insistence on the poetic over the technical, because Lina was right, it did look like the inside of the sun, it looked like something that should not be seen by human eyes, something from the interior of the earth or the interior of a star, something that was normally hidden and that the foundry process made temporarily visible before the cooling and the solidifying and the chasing and the patina covered it over and turned it into something that could be looked at without awe, and this covering-over was necessary because awe was not sustainable, awe was the response to the raw and the raw could not be maintained, the surface had to come, the patina had to be applied, the bronze had to become something other than what it was in the moment of the pour.

They waited for the shell to cool.

This took hours. The bronze inside the shell needed to reach room temperature before the shell could be broken away, because thermal shock — the rapid cooling that occurred when hot bronze met cold air — could cause the metal to crack, and cracking was the thing Oren feared most, more than porosity, more than misruns, more than any of the other defects that could ruin a casting, because cracking was structural, was fatal, was the failure of the alloy itself, and if the alloy cracked the casting was lost and the weeks of work that had gone into it — the armature, the wax, the hollowing, the sprues, the shell, the burnout — were lost with it.

They left the foundry and drove to the bar in the industrial zone and drank coffee and ate cornetti and waited.

Lina said, Tell me about the alloy.

Oren said, Silicon bronze. Ninety-six percent copper, four percent silicon. Traces of manganese and iron.

She said, Why silicon.

He said, It makes the bronze flow better when it is molten. It fills the mold more completely. And it creates a surface that takes patina well.

She said, So the four percent changes everything.

He said, The four percent changes everything.

She said, Four percent, and she was not talking about silicon anymore, or not only about silicon, and Oren knew she was thinking about the percentage of cells in her pancreas that were cancerous, the small fraction of her body that had gone wrong and that was changing everything, the four percent that was not supposed to be there but that was there and that had, like the silicon in the bronze, altered the fundamental properties of the whole.

He reached across the table and took her hand.

Her hand was warm from the coffee cup and he held it and she let him hold it and they sat in the bar in the industrial zone of Pietrasanta, surrounded by truck drivers and factory workers and foundry men, and they held hands across the table like two people on a first date, two people who did not yet know what the other was made of, what alloy, what proportion of elements, and the holding of hands was the oldest and simplest gesture of connection and it meant, in this context, in this bar, on this morning after the pour, what it had always meant, which was: I am here. Which was: You are not alone. Which was: The alloy holds.

They returned to the foundry in the early afternoon.

Roberto said the shell was cool enough. Oren put on his safety glasses and picked up the hammer and the chisel and began to break the ceramic shell away from the bronze.

The shell cracked and fell in pieces, white fragments dropping onto the sand like broken eggshell, and beneath the fragments the bronze appeared, dark and rough and covered with the residue of the ceramic — a thin layer of white that clung to the surface like ash — and the form emerged piece by piece, the vessel, the boat, the hand, the memorial, and it was bronze, it was real, it was no longer wax, no longer void, no longer potential, it was actual, it was here, and Lina watched from the edge of the pouring pit as her husband uncovered the thing he had made and the thing was raw and imperfect and covered in the evidence of its own creation — the sprue stubs protruding from its surface, the seam where the two halves of the wax had been joined, the slight roughness of the ceramic shell's texture transferred to the bronze — and it was not beautiful, not yet, not by any standard that a viewer would recognize, but it was complete, in the way that raw materials were complete, in the way that the quarry face was complete before the sculptor touched it, in the way that a person was complete before the world began to apply its patina.

Lina said, There it is.

Oren said, There it is.

She said, Before you make it beautiful.

He said, Before I make it beautiful.

She looked at the raw bronze for a long time and he did not interrupt her looking because he understood that she was seeing something that he could not see, or that she was seeing the same thing he saw but from a different angle, the way a bronze looked different from every angle because the light caught different facets and the shadows fell differently and the surface, even a raw surface, was never the same surface twice.

She said, It is already beautiful.

And Oren looked at the raw bronze with its sprue stubs and its ceramic residue and its roughness and its imperfection and he tried to see what she saw, the beauty in the raw, the sufficiency of the unfinished, and he could not see it because he was a patinator and a patinator's eye was trained to see the surface that was not yet there, the patina that the bronze was waiting for, the green that would come, the age that would be applied, the beauty that would be made rather than found, and he thought that this was the difference between him and Lina, that he saw what things would become and she saw what they already were, and that both ways of seeing were necessary, were in fact the two elements of an alloy, and that the alloy was their marriage, and that the alloy held.
