Next morning, they made a start on true vermilion.
Framain had brought the book in from the house. He carried it in both hands, as if it'd shatter if he dropped it. He swept a patch clear of dust and ash with his sleeve and laid it down, like someone carrying an injured child.
'We tried it before,' she told Miel, as they waited for Framain to find the right place, 'about five years ago, with the bog sulfur. Didn't work. But Father thinks that sulfur you brought us might be different. No reason to think it'll work where the other stuff didn't, but I suppose it's worth trying. Of course,' she added, 'it was useless for making sweet spirits of vitriol with, so it'll probably be useless for this too. But you never know.'
'There are actually three kinds of sulfur,' Framain said, not looking up from the book. 'As well as the yellow variety, there's the black and the white. Unfortunately,' he lifted his head and looked at them, 'the wretched book doesn't say how you tell them apart, or which one's suitable for the job. Presumably you're just meant to know, by light of nature. I'll need the scales.'
Miel knew where they lived; he darted forward to fetch them, a bit too eagerly. He heard her tutting as he took the rosewood box out of the drawer under the bench. She was bashing something in the big stone mortar; a vicious chipping noise, like a thrush pounding a snail against a stone.
'Quicksilver,' Framain said, with distaste. 'Have we got any left?'
'Yes,' she replied, not stopping her onslaught. 'Wear your gloves, it's filthy stuff.'
Framain didn't put his gloves on, but he handled the thick-walled glass bottle as though it was a live snake or a huge poisonous spider. 'Hold the scales,' she told Miel, as she scooped a spoonful of yellow dust out of the mortar into the left-hand scale pan.
'Two parts of quicksilver, by weight.' Framain said. 'Hold the spoon, would you?'
She held the spoon steady while he tilted the bottle. The stuff that came out was a silvery-gray liquid, the color of polished and burnished steel. Both of them winced a little at the sight of it. He trickled it from the spoon into the right scale pan, a shining silver droplet at a time, until the beam stopped swaying and the little needle above the pivot was dead center. Very carefully, he lifted the right-hand pan, as she hurried to put a clay saucer underneath it; he tipped the pan out, and she put the saucer down on the bench.
'Fine,' Framain said. 'And the same again.'
They repeated the procedure, and Framain emptied the saucer into a different thick-sided glass bottle. 'Get that stuff tidied away before we spill it,' he said, to nobody in particular. Before Miel could move, she'd stoppered the quicksilver bottle and put it back on the long shelf. 'Now we need fresh clay. I dug some this morning, you'll find it in the bucket by the door.'
Like a sculptor with an important commission, Framain scooped and molded the wet brown clay all round the bottle-trickles of brown water squeezed back over the webs between his fingers, and down the back of his hands to his wrists-until it was completely covered. 'Mustn't let any of the vapor get out,' he explained. 'The book doesn't say why, but for all I know it could be deadly poison. It's wise to assume that anything with quicksilver in it is out to get you. Blow the fire, would you?'
Miel worked the bellows until Framain said, 'Fine, that's enough'; then he put the clay-covered mess down on the steel grille over the fire. 'Once the clay's dry, we've got to blow up a good heat. Apparently we've got to listen out for a cracking noise, which means the sulfur's combining with the quicksilver. When the noise stops, it should be ready.' He pulled a face. 'Let's hope so, anyway.'
'The last time we did this, it came out a disgusting brown sludge,' she said. 'And the bottle cracked.'
'We let it get too hot,' Framain said mildly.
(Outside, it had started to rain, a tapping on the thatch, blending with the hiss of the fire; every few seconds a soft plink, as a drip from the roof hit a tin plate on the bench. Miel had to make an effort not to wait for the next one.)
'It was the wrong sulfur,' she replied. 'It says in the book there're three kinds, doesn't it?'
'The book isn't always reliable,' Framain said with a sigh. 'But it's the only one we've got, so we just soldier on.' He bent down to peer at the clay mess. 'Open the vent a touch, will you? The fire's starting to run away a bit.'
Nothing much could be done while the clay was drying. Framain went back to the bench, leafed through the book, fetched a couple of jars but didn't open them, went back and checked the fire, put one of the jars back and got out two more, looked something else up in the book, scraped rust off a spoon with the back of a chisel. 'He's always nervous,' she said, as though he wasn't standing only a few yards away, 'ever since he let a crucible get too hot and it shattered. Burning pitch everywhere. I got burned-look, you can still see, on the back of my arm here-and some embers got in the underside of the thatch, we nearly lost the roof and-'
'Accidents happen,' Framain said to a sealed jar. 'Only to be expected, since we don't really have a clue what we're doing. Because, of course, if anybody'd done it before, there'd be no point doing it again. That's what discovery means.'
Miel took a step back out of instinct. He had a feeling this conversation, or others just like it, had been going on for many, many years. Two people talking at each other with intent to wound, like overcautious fencers probing each other's flawless guards. Just another manifestation of love, he decided. He'd seen the same sort of thing with married couples. For something to do, he went and looked at the fire.
'If we can produce a true vermilion,' Framain told the jar, as if explaining his scheme to a crowd of skeptical investors, 'we stand a chance of being able to make the soft white for backgrounds; it's a mix of the white lead tarnish cooked yellow, vermilion and ordinary flake-white, with green-earth to balance out impurities. We need to get the background right before we can start on the colors themselves, of course, because otherwise we won't know how the colors will react with the background. For example, viridian-'
'It's ready,' she interrupted.
'Are you sure? If we give it the full heat before it's thoroughly dried-'
'Look for yourself.'
And yet, what closer bond of love could there be than between a father and his daughter? Miel had been watching closely for some time now; everything one of them did seemed to irritate the other beyond measure. There'd been days when both of them had talked to him, as if to an interpreter, rather than acknowledge the other one was actually there in the room. He wondered about the mysterious business partner, the one who'd absconded or been thrown out. Had they talked through him this way? If so, no wonder the poor man left.
'Ready.' Framain's voice was unusually tense. 'Blow up the fire a bit, will you? More coal.'
A drip hit the tin plate, making Miel jump. Was it his imagination, or was something about to happen? Probably just the atmosphere between Framain and his daughter, making him nervous. He dug the scoop into the charcoal scuttle.
'We're running low on fuel,' she said. 'And when that's gone, with the war and everything…'
Framain didn't bother to reply; he shushed her. They were supposed to be listening out for a cracking noise, Miel remembered. He could smell damp, a hint of moldy straw. I'm just in the way here, he thought, they don't need me for anything. For no real reason, he drifted over to the bench and glanced down at the book, remembering the first time he'd seen it.
…To make flake-white, place sheets of lead beaten thin in a wooden box, cover with vinegar mixed equally with urine, leave for a month. To convert flake-white to red lead, grind fine and heat in a new pot. To make Mezentine green, place thin copper foil…
'The book,' he heard himself say. 'Where did you get it from?'
'It belonged to my former partner,' Framain said, not looking round. 'He had quite a library.'
'Half the things in that book simply don't work,' she put in. 'Whoever wrote it must've made them up and stuck them in just to fill it out.'
'It's the only book we've got,' Framain said wearily. 'And some of it-'
'There's a perfectly ridiculous thing in there,' she went on, ignoring him, 'about hardening chisels by quenching them in the urine of a red-headed boy; or, if you don't happen to have one handy, goats' wee filtered through dry bracken will do almost as well. For all we know, the whole book could be a spoof; you know, a parody, in-jokes for colormen and engineers. And here we are, following it religiously as if it's gospel.'
'Quiet.' Miel had heard it too, a sharp click, like twigs snapping.
'In fact…' She'd raised her voice, and it was higher, too. 'In fact, whoever wrote it seems to have had a thing about urine, because he tells you to use it in practically everything, the way the Vadani use parsley in cooking. Makes you wonder what-'
