The questions came one at a time.
Gerald did not plan them. They surfaced from the work — each one arriving after a chore or a conversation or a long stretch of watching, specific and waiting. He finished the stable work, crossed the yard, stood at the Hot House doorway — and the question was there, in his chest, ready.
The first one was about colour.
He had been thinking about it since the sand day with Lil Bill, since Pim had walked him through the three zones on the beach and Gerald had scooped the reddish sand from the middle stretch and been told it would make glass green or amber. He had thought about it again at the Rainbow Wall, crouching beside his blue fragment in the mortar. He had thought about it at Grandfather’s store, holding the red piece to the high window and watching the light come through it thick and slow.
He stood at the workshop doorway and asked Tomis what made the blue.
Tomis was banking frit at the back shelf. He finished the jar he was working on, capped it, set it in line with the others. Then he turned and looked at Gerald in the doorway — directly, without the deliberation Da brought to the looking, without the reading Pim brought to it. Tomis looked at things once and was done.
“Cobalt,” he said.
He crossed to the sample rack on the wall nearest the door. Gerald had seen the rack before, from the doorway — a wooden frame with narrow shelves holding short rods of coloured glass, each one about the length of Gerald’s hand. The colours graded from one end to the other. Blues at the left, purples beside them, then greens, then the ambers and browns, then a cluster of colours Gerald did not have names for — a smoky grey, a deep red, a pale yellow that caught the furnace light and kept it.
Tomis took a blue rod from the rack and brought it to the doorway.
“Hold it up.”
Gerald took the rod. It was cool — long since finished, the glass smooth and dense between his fingers. He raised it to the afternoon light. The blue came through deep and even, without the warmth of the amber rods on the shelf or the green’s tendency to shift where the glass was thinner.
“Cobalt oxide,” Tomis said. He was leaning against the door frame, arms crossed, watching Gerald hold the rod to the sky. “A small amount. Less than you would think. Too much and the blue goes black.”
“How much?”
“Depends on the batch.” Tomis reached behind him and took a jar from the frit shelf nearest the door. The jar was small, heavy, and the powder inside was dark — so dark it looked black until Tomis tilted it and the light caught the surface and the blue appeared, faint and vivid at once, like a bruise underneath the dark. “You measure by weight. Same sand, same temperature, same time in the furnace — change the cobalt by a grain and the blue changes.”
Gerald looked at the powder. Tomis offered the jar and Gerald dipped two fingers in. The frit was fine, dry, cooler than he expected, and the colour left a faint residue on his fingertips that was nearly invisible against the mineral stain already in his skin.
“Purple?”
“Manganese.” Tomis recapped the cobalt and took another rod from the rack — deeper, darker, the colour of the late plums Mam grew on the south wall of the greenhouse. “Same principle. Different mineral, different colour.”
Gerald looked at the rod. He had shovelled that grey sand into sacks on a morning when his arms burned and the tide was coming in. It had been colourless in his hands. He had not seen the purple in it.
“Green?”
“Copper.” A third rod, this one the colour of the deep pool below the cliff. “Copper gives you green. Iron gives you amber. Iron is in everything — the sand, the tools, the furnace lining. You have to work to keep iron out.”
A sound from the yard cut through the conversation. Aaron had come around the corner of the workshop carrying a crate of sand from the sifting shed. The crate caught the edge of the rain barrel and the bottom corner split and sand poured through the gap in a pale stream across the gravel. Aaron dropped to his knees, trying to hold the crate together, but the slats were pulling apart and the sand kept coming. He said something under his breath that Gerald could not hear.
Tomis straightened from the door frame.
“Set those down,” he said to Gerald, meaning the rods.
Gerald put them on the shelf. By the time he turned back, Tomis was already in the yard, taking the broken crate from Aaron’s hands and tilting what remained of the sand into the intact half. Aaron’s face was tight. His hands were covered in sand and there was a scrape across his palm from the split slat.
“How much was in it?” Tomis asked.
“Full.” Aaron looked at the sand on the ground. A morning’s sifting work, or most of it, scattered across the gravel in a fan that was already mixing with the dirt.
Tomis studied the mess. “Sweep what you can into the bucket. The rest is gone.”
Aaron went for the broom. Gerald stood in the doorway. The colour rods sat on the shelf behind him, cobalt and manganese and copper, still holding their blues and purples and greens. The sand on the gravel was grey and formless and had no colour in it at all.
Tomis came back to the doorway. He picked up the copper rod and turned it once, checking that the fracture edge near the base had not been chipped when Gerald set it down. It had not.
“Iron is the most common,” he said, picking up where he had left off as if nothing had interrupted. “Most glass has some amber in it whether you wanted it there or not.”
He said this with the mild expression of a man describing weather he had long since stopped arguing with.
Gerald watched the green rod in the light. He tilted it. The colour shifted — darker where the rod was thick, paler where it thinned. He tilted it back. The colour returned.
“Did your father teach you this?”
The question came from the same place all the questions came from. Gerald did not plan it. It was there and then it was out.
Tomis’s hands stopped.
He had been reaching for the frit shelf to put the rods back. His hand stayed in the air for a moment, fingers extended, the way a hand stays when the body forgets what the hand was doing. Then it came down to his side.
“No,” Tomis said. “Your grandfather did.”
Gerald looked at him. Tomis was not leaning against the door frame anymore. He was standing straight, his arms at his sides, and something had gone out of the ease that Gerald saw in him every morning at the community table. His face was the same face — lean, patient, the scars on his hands from years at the furnace visible in the light from the yard. But it was not wearing the same expression. Gerald had never seen Tomis look like he was remembering something that hurt.
Tomis turned away. He put the rods back on the shelf, one at a time, slotting each into its place in the colour sequence. His back was to Gerald. His shoulders were set in a way Gerald recognized from watching Da at the bench after a piece went wrong — the posture of someone putting themselves back into order.
When he turned around, he was Tomis again. The ease was back. Or something close enough to it that Gerald would not have known the difference if he had not seen the moment before.
“Clarence Glass,” Tomis said. “He taught me cobalt, manganese, copper. He taught me what too much iron looked like and how to read the flux. I was twelve.”
Gerald held very still. Tomis was not answering a question anymore. He was saying something he had decided to say, and Gerald did not want to break the deciding.
“He was patient with me.” Tomis looked at the colour rack. “I was not always patient with the learning.”
Then he reached past Gerald for the broom leaning against the outside wall and went to help Aaron with the sand.
The questions kept coming.
Not every day. Some mornings the stable work went long, or the greenhouse needed attention past the midday, or the yard was busy with deliveries and the Hot House doorway was not a place to stand. But two or three times a week, Gerald finished his chores and crossed the yard and the next question was there.
He asked about the furnace temperature. Tomis explained the rune channels and how they held their heat — not burning, not consuming anything, the aether flowing through the carved lines in the refractory lining and becoming heat as steadily as the river became motion at the waterwheel. He asked about the annealing oven. Tomis described the cooling cycle — how glass could not be rushed from hot to cold without cracking, how the difference between a sound piece and a cracked one was often nothing more than patience.
Gerald thought about Mam’s rosemary. He did not say so.
He asked about the blowpipe — what it was made of, how heavy it was, why Da’s pipe was different from the one Edric used. Tomis answered without lecture. Each answer was complete, with edges. Gerald took each one and set it beside the other things he knew — lined up, touching, each one distinct.
Tomis brought pieces to the doorway. Not finished work. A rod that had gone wrong in the colour mix, streaked rather than even, the blue bleeding into the clear in a pattern that was accidental and interesting and unsellable. A flat disc of amber glass that had cracked in the annealing, the fracture running through it in a line so clean it looked intentional. A handful of frit from three different jars, poured into Gerald’s cupped palms so he could feel the grain of each — the fine powder of the cobalt, the coarser granules of the manganese, the copper’s grit that sat between the two.
Gerald turned the streaked rod and watched the blue-into-clear boundary move as the angle changed. He ran his thumb along the fracture line of the cracked disc — not jagged, the two faces of the break fitting together as precisely as pieces of a puzzle that had chosen its own shape. He let the frit run through his fingers back into Tomis’s jars and watched the colours fall — black-dark cobalt, grey-dark manganese, green-dark copper, each one carrying its eventual colour hidden inside the dark.
Through the greenhouse panels, a crack had appeared in a pane near the far corner — a line running from the bottom edge to about knee height, webbed fine enough to catch the sun. Gerald had asked Mam about it that morning. “The cold snap last week,” she had said, already writing something in the ledger she carried to the greenhouse on inspection mornings. She had not looked up. The crack was on a list Gerald could not see, and the list was longer than the crack.
He began to carry a piece of glass in his pocket.
It was not one of Tomis’s samples. It was a piece he found in the discard pile behind the workshop — a flat, irregular chunk, greenish, about the size of his palm, rough on the fracture edges where it had broken from a larger piece. The green was not the green of the copper rod. It was paler, less certain of itself, a green with yellow in it at the thick centre and a faint blue tinge at the edges where the glass thinned.
He put it in his pocket.
It sat there — present, private, a weight against his leg when he walked. He took it out on the workshop step in the afternoons and turned it in the light. In full sun the yellow showed through, warm and bright, and the edges went almost clear. In the shade the blue came forward and the yellow retreated. In the last light of the afternoon, when the workshop step sat in the building’s shadow, the green went deep and even and the piece looked like something that had made up its mind.
He did not show it to Tomis. He kept it in his pocket during the doorway conversations and felt its edges with his thumb while Tomis talked about flux ratios and gather consistency. The rough fracture edges softened with handling, the sharpest points worn down by his thumb in the same creases where the mineral stain, the stable grime, the forge warmth had all settled in their separate layers.
On a Tuesday, Tomis took a piece from the sample shelf. Not a rod. A chunk of raw glass, larger than Gerald’s piece, greenish-grey, rough and unfinished. He extended it toward Gerald.
“What do you see?”
Gerald took it. Heavier than his own piece. Warmer — it had been sitting on the shelf near the furnace wall. He turned it in both hands.
The green was not a single green. Where the glass was thickest, it carried yellow — warm, dense, the light entering and slowing down inside. Where it thinned toward the edges, the green shifted toward blue, cooler, and the light came through carrying the colour with it onto Gerald’s palm in a pale stain that moved when he tilted the glass. Two tiny bubbles sat trapped near the centre, bending the light around them.
He stayed with it long enough that the warmth from the shelf faded and the piece cooled to the temperature of his hands, and Gerald could no longer tell which warmth was which.
Tomis watched him from the door frame. He had not spoken.
“It is green,” Gerald said. “But the green has yellow in it at the centre and blue at the edges. The yellow is where the glass is thickest. The blue is where it gets thin.” He turned the piece. “The light goes into it. Not off it. Through it. It comes out different.”
He stopped. The bubbles near the centre caught the late light.
“It is warm,” he said. “From the shelf. But the warmth is going.”
Tomis nodded. A single dip.
“What do you think it wants to be?”
Gerald looked at him. Glass did not want things. Glass was a material. It sat on shelves and filled Grandfather’s store and kept gooseberry preserves and caught the sun in the greenhouse panels and did not want anything because it was glass.
But Tomis had asked it directly, as a question that expected an answer because the question was real.
Gerald looked at the piece. The green with yellow in it. The blue at the thinning edges. The two bubbles. The warmth that had been the shelf’s and was now his.
He did not have an answer.
“I do not know,” he said.
Tomis took the piece from Gerald’s hands and set it on the shelf. Then he picked it up again and offered it.
“Take it home,” he said. “Think about it.”
Gerald put the piece in his pocket. It sat beside his other piece, the discard-pile green, and the two shapes pressed against his leg. He crossed the yard. The greenhouse panels caught the late afternoon light and threw a brief brightness across the gravel. From the kitchen doorway, Nessa’s voice reached him, broken by laughter. The furnace hummed. The waterwheel creaked.
He ate supper. He swept the front hall. He sat with Sable in the corridor while she read and the evening cooled around them. Tom’s footsteps crossed the dining room. Mary closed the kitchen. The stairs creaked under Edric’s boots taking them two at a time.
He went to bed.
The piece of glass sat on the table beside his bed, next to the lamp. The green was dark without the sun. The yellow in the centre was gone, or hidden. The bubbles were invisible. The edges were just glass.
Gerald lay on his side and looked at it.
What did it want to be?
He did not know. The question was not like the other questions. Those had answers Tomis could give — cobalt, manganese, copper. This one did not. This one belonged to the glass, or to Gerald, or to the space between them.
He closed his eyes. The furnace hum came through the walls, low and steady. The glass sat on the table in the dark.
When he opened his eyes in the morning, the first thing he did was pick it up.
