How deep do we go? : I want to know what you're thinking. But I remember moments in years passed when I pushed too hard, invaded depths and sought out answers like stolen treasures. Before you, I was with wooden statues, men who couldn't tell me what they were feeling, even when it was written in devastating ink all over their faces. How dare I give away their secrets to themselves? Now, I hold out my palm and without asking, you finger a little word, a sign; you travel along a canal to meet me. #writing #writersofinstagram #mindfulness #handwriting #writingnotes #art #passionate #torontoartists #torontowriters #likeforfollowers #likeforlikes #the6ix #poetry #poetrygram #postitpoetry #writingcommunity #writer #writers #writerscommunity #words #wordstoliveby #notes #artwork #torontoart #instawrite #paper #paperart #lifestyleblogger

I drew a quick sketch in

I drew a quick sketch in plan for my next art project, I have to choose a artist that inspires and draw in their style so I decided to do @happydartist her work motivates me so much and I love it, it's so pretty and it always gives a sense of supernatural which seems so cool. I will try to post the final copy when I can. #art #artistsoninstagram #artist #teenageartist #teenartist #teenart #draw #drawing #sketch #sketchbook #semirealistic #pencil #roughdraft #paper #artwork #artistic #artgram #happydartist

Rumbo a casa y con la cla

Rumbo a casa y con la clara intencin de que Catica Jimena sea mi prxima lectura! Despus de acabar La chica que dejaste atrs, claro... he fracasado estrepitosamente con mis propuestas de verano, espero arreglarlo un poco con la vuelta a la rutina. Lo conseguir ? . . . #books #book #read #caticajimena #reading #reader #page #pages #paper #instagood #kindle #nook #library #neira #bestoftheday #bookworm #readinglist #love #photooftheday #imagine #plot #bookstagram #story #literature #literate #stories #words #text #nordichome #nordicdeco

An extract on #paper

The pulp papermaking process is said to have been developed in China during the early 2nd century CE, possibly as early as the year 105 CE, by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BCE in China. The modern pulp and paper industry is global, with China leading its production and the United States right behind it.

The oldest known archaeological fragments of the immediate precursor to modern paper, date to the 2nd century BCE in China. The pulp papermaking process is ascribed to Cai Lun, a 2nd-century CE Han court eunuch. Its knowledge and uses spread from China through the Middle East to medieval Europe in the 13th century, where the first water powered paper mills were built. Because of paper's introduction to the West through the city of Baghdad, it was first called bagdatikos. In the 19th century, industrialization greatly reduced the cost of manufacturing paper. In 1844, the Canadian inventor Charles Fenerty and the German F. G. Keller independently developed processes for pulping wood fibres.

Before the industrialisation of the paper production the most common fibre source was recycled fibres from used textiles, called rags. The rags were from hemp, linen and cotton. A process for removing printing inks from recycled paper was invented by German jurist Justus Claproth in 1774. Today this method is called deinking. It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials from ragpickers.

The word "paper" is etymologically derived from Latin papyrus, which comes from the Greek (papuros), the word for the Cyperus papyrus plant. Papyrus is a thick, paper-like material produced from the pith of the Cyperus papyrus plant, which was used in ancient Egypt and other Mediterranean cultures for writing before the introduction of paper into the Middle East and Europe. Although the word paper is etymologically derived from papyrus, the two are produced very differently and the development of the first is distinct from the development of the second. Papyrus is a lamination of natural plant fibres, while paper is manufactured from fibres whose properties have been changed by maceration.

To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papersnot to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose. There are three main chemical pulping processes: the sulfite process dates back to the 1840s and it was the dominant method extent before the second world war. The kraft process, invented in the 1870s and first used in the 1890s, is now the most commonly practiced strategy, one of its advantages is the chemical reaction with lignin, that produces heat, which can be used to run a generator. Most pulping operations using the kraft process are net contributors to the electricity grid or use the electricity to run an adjacent paper mill. Another advantage is that this process recovers and reuses all inorganic chemical reagents. Soda pulping is another specialty process used to pulp straws, bagasse and hardwoods with high silicate content.
