Mineral and Pigment Dyestuffs. These colours are insoluble in water and alcohol. They are either fixed on the fibre by mechanical means or by precipitation. For example, you use blacklead or plumbago to colour or darken your hats, and you work on this pigment colour by mechanical means. I will show you by experiment how to fix a coloured insoluble pigment in the fibre.
I'll write to her, and we'll put it in the big letter-box at the gate as we go out. Has anyone got a bit of pencil and a scrap of paper?" Gerald had a note-book, with leaves of the shiny kind which you have to write on, not with a blacklead pencil, but with an ivory thing with a point of real lead.
Miss Pillby, who never opened a book for her own pleasure, who cared nothing for music, and whose highest notion of art was all blacklead pencil and bread-crumbs, had plenty of vacant space in her mind for other people's business. She was a sharp observer of the fiddle-faddle of daily life; she had a keen scent for evil motives underlying simple actions.
He taught a very famous chemist, Lavoisier, about ninety years ago, how to burn a diamond in oxygen and a very difficult trick that is; and Lavoisier found that the diamond when burnt turned almost entirely into carbonic acid and water, as blacklead and charcoal do; and more, that each of them turned into the same quantity of carbonic acid, And so he knew, as surely as man can know anything, that all these things, however different to our eyes and fingers, are really made of the same thing, pure carbon.
She considered a moment, and then declared impishly, "Because it doesn't seem possible that a man like you should never say 'Damn." He laughed outright. "Well, I'm not going to tell tales out of school; but if you'd only got one pair of brown boots in the world and one pair of brown gaiters, and the boy tried to clean them with blacklead and paraffin oil!..."
If she had any kindness left for him she would suffer to watch him eating well-nigh uneatable food, grooming a horse, sweeping a stable, polishing trestle-legs with blacklead, scrubbing floors, sleeping on damp straw, carrying coals, doing scullion-work for uneducated roughs, being brow-beaten, bullied, and cursed by them in tight-lipped silence not that these things troubled him personally the less idle leisure for thought the better, and no real man minds physical hardship there is no indignity in labour per se any more than there is dignity....
On the last trip made to the wreck of the Red Eric, just before the great storm that completed the destruction of that ship, the captain had brought away in his pocket a couple of note-books. One of these he kept to himself to jot down the chief incidents of the intended voyage; the other he gave to Ailie, along with a blacklead pencil.
Bill Bates concurred, so they borrowed a piece of blacklead pencil from the 'coddy' and made out their time sheets, took off their aprons, put them into their tool bags, and went to the office for their money, which Misery passed out to them through the trap-door.
And surely that is worth knowing, that you may be helping to make chalk, or to make wood, every time you breathe. Well; that is very curious. But now, ask him, What is carbon? And he will tell you, that many things are carbon. A diamond is carbon; and so is blacklead; and so is charcoal and coke, and coal in part, and wood in part. What?
On leaving the circus, very naturally we went to the cafe where the first part of the little dinner comedy had been enacted. We encountered both artists, professional or amateur, of blacklead and bristol board, but we met a waiter there who was an artist in his line. I ordered a cigar of him, specifying that the cigar should be of a brand made in Havana and popular in the States.
