Sculptures were not finished just with hammer and chisel—they were also smoothed with rags of varying roughness. Or sandpaper or emery. Finally sculptures could be given a protective layer of wax that could be buffed to a high finish. Chisels also come in many different sizes, shapes and weights. There are ones used for simply removing large areas of stone, ones for defining details like curls of hair, blades of grass and other textures.

- make fermented indigo dye

  • slice indigo to put into a jar, replace indigo with lime backed with oyster shells. When lime is added, the pigment deposits settle downward. The top liquid can be discarded, leaving sediments at the bottom to solidify. When lyebis added to the indigo sediment and fermented for 7 to 10 days, tge pigment and lime separate and form bubbles. Also called flower liquidization, this process shows color shifts at various points. Dyeing in the liquid initially yields light green hues, which switch to turquoise-tinted blue after being left to dry. After at least 8 repetitions, the deepest shade of navy is produced.
Glue
- 製作黃魚肚膠水也是一件很費心思的事情，首先要花上好幾個小時慢慢把魚肚煮爛，一點點地搗碎成膠質狀，然後趁熱把它繞成絲線冷卻凝固，每次用的時候再取一小段下來煮水化開。」這也是倦勤齋修繕時間長達三年之久的原因之一，因為北京的冬天太冷，膠水一離開加熱的鍋子就馬上會凝固，所以幾乎一進入冬季修繕工作就無法進行了。除了黏合的作用之外，在修復乾隆寶座和屏風時，這種特製膠水也起到了巨大的作用。何福禮介紹，清洗是修繕工作的第一步，但當時寶座和屏風上的竹絲一沾水就掉落下來。一天早上，他一邊思考着解決辦法，一邊從電飯煲裏盛稀飯，突然有了靈感，先用電飯鍋對專用膠水進行加熱稀釋，再用稀釋後的膠水進行清洗。果然，寶座不僅露出了廬山真面目，保留了原先的色彩，連輕觸即落的竹絲和竹簧也得到了有效固定。http://pdf.wenweipo.com/2021/02/01/a14-0201.pdf

tallow - a hard fatty substance made from rendered animal fat, used (especially formerly) in making candles and soap.Tallow is a rendered form of beef or mutton fat, and is primarily made up of triglycerides. It is solid at room temperature. Unlike suet, tallow can be stored for extended periods without the need for refrigeration to prevent decomposition, provided it is kept in an airtight container to prevent oxidation.


soap
- The stem word for “soap” in all European languages is Latin sapo, and soap really isn’t nothing but natron salt of fatty acids. Soap is easy to manufacture from any fats, and usually the offal of any slaughtered animals were cooked into soap with the presence of lye. What happens is transesterification; the triglycerides react with lye, forming sodium salts of fatty acids and glycerol.

Lye is sodium hydroxide, and by using potash instead you get soft soap (liquid soap). Any fats or vegetable oils not suitable for human or animal consumption could be turned into soap with soda, lye, caustic soda or potash. So soap was used as soap in the Middle Ages. https://www.quora.com/What-was-used-as-soap-in-the-medieval-times

Michel Eugène Chevreul (31 August 1786 – 9 April 1889) was a French chemist whose work influenced several areas in science, medicine, and art. His early work with animal fats revolutionized the manufacture of soap and of candles and led to his isolation of the heptadecanoic (margaric), stearic, and oleic fatty acids. 

Gall soap, however, uses the bile of an animal—from it’s gall bladder, just under and behind the liver. Bile is what the body uses to break up fats into fatty acids during digestion in the first lengths of the small intestines. Bile/gall acts as a surfactant in the soap much like sodium dodecyl sulfate does in Dawn dishwashing liquid. The bulk of the soap,is composed of lye (another interesting story for another day). The gall improves the lye’s ability to break up grease and oils, thus better cleaning whatever it is you are washing. It also “tones down” the caustic effect of the lye in the soap a little.The only way to get this gall is to harvest the gall bladder from the dead animal. How this harvest is done is what will determine whether the methodology qualifies as “abuse” or not.https://www.quora.com/What-is-gall-soap-and-how-is-it-sourced-Are-any-animals-harmed

Turpentine (also called spirit of turpentine, oil of turpentine, wood turpentine and colloquially turps) is a fluid obtained by the distillation of resin from live trees, mainly pines. It is mainly used as a solvent and as a source of materials for organic synthesis.The word turpentine derives (via French and Latin) from the Greek word τερεβινθίνη terebinthine, the feminine form (to go with the feminine Greek word for resin) of an adjective τερεβίνθινος derived from the Greek noun τερέβινθος, the name for a species of tree, the terebinth tree.[5] Mineral turpentine or other petroleum distillates are used to replace turpentine, but they are very different chemically.The two primary uses of turpentine in industry are as a solvent and as a source of materials for organic synthesis. As a solvent, turpentine is used for thinning oil-based paints, for producing varnishes, and as a raw material for the chemical industry. Its industrial use as a solvent in industrialized nations has largely been replaced by the much cheaper turpentine substitutes distilled from crude oil. Turpentine has long been used as a solvent, mixed with beeswax or with carnauba wax, to make fine furniture wax for use as a protective coating over oiled wood finishes (e.g., tung oil).

- 突板（つきいた、突き板、ツキ板ともIn woodworking, veneer refers to thin slices of wood and sometimes bark, usually thinner than 3 mm (1/8 inch),[1] that typically are glued onto core panels (typically, wood, particle board or medium-density fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet floors and parts of furniture. They are also used in marquetry. Plywoodconsists of three or more layers of veneer. Normally, each is glued with its grain at right angles to adjacent layers for strength. Veneer beading is a thin layer of decorative edging placed around objects, such as jewelry boxes. Veneer is also used to replace decorative papers in Wood Veneer HPL. Veneer is also a type of manufactured board.Veneer is obtained either by "peeling" the trunk of a tree or by slicing large rectangular blocks of wood known as flitches. The appearance of the grain and figure in wood comes from slicing through the growth rings of a tree and depends upon the angle at which the wood is sliced.

  • Historically veneers were also sawn, but this is more wasteful of wood. Veneering is an ancient art, dating back to at least the ancient Egyptians who used expensive and rare wood veneers over cheaper timbers to produce their furniture and sarcophagi.[2] During the Roman Empire, Romans also used veneered work in mass quantities.
  • In dentistry, a veneer is a layer of material placed over a tooth. There are two main types of material used to fabricate a veneer: composite and dental porcelain. 
- 桐油是取自大戟科油桐屬樹木油桐種子的油，在空氣中氧化經聚合反應生成緻密的漆膜；和其他乾性油比較，有乾燥快、比重小、附着力強、耐熱、酸、鹼等優點。桐油原產中國，傳統上用來塗抹保護木器、製造油布、油紙等防水材料，調製油泥鑲嵌縫隙，中醫用來調和膏藥等外用藥。桐油在現代用於做木器油漆、油墨、製造合成樹脂等。「桐油灰」過去用來鑲在玻璃邊防止漏水；現在多改用玻璃膠。中國傳統的桐油來自三年桐（Aleurites fordii Hemsi.）和木油桐（Vernicia montana，又名千年桐）。日本油桐（Aleurites cordata Thunb.）所產的油稱為日本桐油。 油桐種子含油率一般在35％以上，其中種仁含油率60％左右。成熟的種子採收後，去除果皮和種皮，用壓榨的方法榨油，剩餘的麩餅還可以進一步用溶劑萃取。這樣製得的生桐油外觀淡黃、暗紅或暗黑色，分別稱為白／紅／黑桐油。生桐油乾燥速度較慢，而且漆膜的透明性和粘性較差。生桐油加一氧化鉛等進一步熬製成為熟桐油，又稱光油，更加適合做塗料。The tung oil tree originates in southern China and was cultivated there for tung oil, but the date of cultivation remains unknown.[3] During the Song Dynasty, tung oil was used for waterproofing on ships.[4]The word "tung" is etymologically derived from the Chinese 桐 tóng.[5] The earliest references for Chinese use of tung oil is in the writings of Confucius around 500 to 400 BC

coating
- Epoxy is either any of the basic components or the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, use in electronics/electrical components/LEDs, high tension electrical insulators, paint brush manufacturing, fiber-reinforced plastic materials and structural adhesives. Epoxy is sometimes used as a glue (see image at right).Epoxy is either any of the basic components or the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans).

Soda ash is most commonly used in:
  • Manufacture of glass, where it reduces the melting temperature of the sand used in glass formation and helps in the 'workability' or shaping of glass articles such as tableware and float glass,     
  • Making soaps and detergents, where it is employed as a builder, or filler, to give a smoother surface,      
  • Production of chemicals such as sodium silicate, sodium bicarbonate and percarbonate, and sodium chromate and dichromate,    
  • Pulp and paper manufacture, water treatment, effluent treatment, metallurgy and drugs.     
sharpening tool
- 砥石 磨刀石，又稱砥礪、礪石  Sharpening stones, water stones or whetstones are used to sharpen the edges of steel tools and implements through grinding and honing.Examples of items that can be sharpened with a sharpening stone include scissors, scythes, knives, razors, and tools such as chisels, hand scrapers, and plane blades.Sharpening stones come in a wide range of shapes, sizes, and material compositions. Stones may be flat, for working flat edges, or shaped for more complex edges, such as those associated with some wood carving or woodturning tools. They may be composed of natural quarried material, or from man-made material.Stones are usually available in various grades, which refer to the grit size of the abrasive particles in the stone. Grit size is given as a number, which indicates the spatial density of the particles. A higher number denotes a higher density and therefore smaller particles, which leads to a finer finish of the surface of the polished object.The Roman historian Pliny described use of several naturally occurring stones for sharpening in his Natural History. He describes the use of both oil and water stones and gives the locations of several ancient sources for these stones.The use of natural stone for sharpening has diminished with the widespread availability of high-quality, consistent particle size artificial stones.As a result, the legendary Honyama mines in Kyoto, Japan, have been closed since 1967. Belgium currently has only a single mine that is still quarrying Coticules and their Belgian Blue Whetstone (BBW) counterparts.Modern synthetic stones are generally of equal quality to natural stones, and are often considered superior in sharpening performance due to consistency of particle size and control over the properties of the stones. For example, the proportional content of abrasive particles as opposed to base or "binder" materials can be controlled to make the stone cut faster or slower, as desired.[7] Natural stones are often prized for their natural beauty as stones and their rarity, adding value as collectors' items. Furthermore, each natural stone is different, and there are rare natural stones that contain abrasive particles in grit sizes finer than are currently available in artificial stones.[citation needed]One of the most well-regarded natural whetstones is the yellow-gray "Belgian Coticule", which has been legendary for the edge it can give to blades since Roman times, and has been quarried for centuries from the Ardennes. 《山海经·西山经》已經有磨刀石的記載了[1]。磨刀石，舊稱砥礪，細者为砥，粗者为砺。磨刀石又可分為页岩、粉砂岩、砂岩等。松花石是一種磨刀石，滿清八旗入關前常以松花石製成磨刀石。

water from air
- Earlier this year Zero Mass Water launched the residential version of its Source Hydropanel at the Consumer Electronics Show (CES) in Las Vegas.It’s estimated there are 71 companies to date, with 32 companies actively selling in a market currently worth between $2m-$10m per year, according to the ‘Atmospheric Water Capture’ BlueTech Horizon Scan report.Companies operating in this space include Majik Water, Watergen, SkySource, SunToWater, Drupps, Genaq and new market entrant, Kara Water. In 2018, the Skysource/Skywater Alliance won the $1.75m Water Abundance XPRIZE as a solution to harvest “fresh water from thin air”. Technology sophistication varies greatly in the AWG market, from fog harvesting nets to smartphone monitored, digitally enabled rooftop panels.According to the BlueTech report, the three most commercially relevant AWC processes include: Cooling condensation (or mechanical refrigeration): air is then passed over a cooled surface or coil, that contains a refrigerant, which cools the water vapour below its dew point, causing condensation. Desiccants (i.e. hygroscopic materials): air is pulled in by a fan, but not cooled below the dew point of water vapor. Instead, water molecules adsorb to the surface of the sorbent until saturation (i.e. maximum adsorption capacity) is reached. To release the water, the desiccant is then heated or boiled (50-160°C depending on sorbent).Fog harvesting: large meshed nets made of a polymer are set up vertically and placed in areas where water droplets are captured and are collected in a reservoir through gravity.https://www.aquatechtrade.com/news/water-treatment/zero-mass-water-why-all-the-hate/

Un hydrolat (ou eau de distillation) est un extrait de plante, aromatique ou non, obtenu par entraînement à la vapeur. Font partie des hydrolats, les eaux florales, obtenues à partir des fleurs1.Herbal distillates, also known as floral waters, hydrosols, hydrolates, herbal waters, and essential waters, are aqueous products of hydrodistillation. They are colloidal suspensions of essential oils as well as water-soluble components obtained by steam distillation or hydrodistillation (a variant of steam distillation) from plants/herbs. These herbal distillates have uses as flavorings and cosmetics (skin care). Popular herbal distillates for skincare include rose water, orange flower water, and witch hazel. Rosemary, oregano and thyme are very popular hydrosols for food production.Herbal distillates are produced in the same or similar manner as essential oils. However, essential oils will float to the top of the distillate where it is removed, leaving behind the watery distillate. For this reason the term essential water is an apt description. In the past, these essential waters were often considered a byproduct of distillation, but are now considered an important co-product.[1] The produced herbal waters are essentially diluted essential oils at less than 1% concentration (typically 0.01% to 0.04%).[2] Several factors, such as temperature and an herb's growth cycle, impact the characteristics of a distillate, and therefore influence the timing of the distillation. Rosemary, for example, should be distilled in the peak of summer before it flowers.

Ordinary glass panels can act as solar panels when a layer of nanoparticles is sandwiched between two panes. This could help us take advantage of solar energy in cities where space for solar panels may be limited.“If we’ve done our job, no one will even know that they’re there,” says Hunter McDaniel at UbiQD, a materials manufacturing firm in the US. He and his colleagues have developed transparent solar panels that are indistinguishable from regular glass.Read more: https://www.newscientist.com/article/2253816-windows-become-transparent-solar-panels-with-added-nanoparticles/#ixzz6XseW9GV8

*****法國設計的新型鹽水電池燈HYDRACELL將會大派用場。該燈利用基本化學電解原理發電，用家只需在內注滿7.5%濃度的鹽水，就可直接亮燈或插上手機充電。每換一次鹽水，HYDRACELL可亮燈一百小時，或輸出能充滿十部手機的電力，比任何一款充電寶更強。更值得一提的是，發電產生的廢水不會污染環境，即使戶外露營都可安心使用。https://orientaldaily.on.cc/cnt/china_world/20200618/00180_043.html

中文大學的研究團隊利用一種護膚霜常用成分，研發了一款水系鋰離子電池電解液，令材料成本可降低最多達95%，加上不易燃、毒性低，相對環保，更能提供穩定的電壓。有關研究結果已刊登於國際期刊《自然材料》。盧怡君的研究團隊在先前對水系鋰離子電池的研究基礎上，利用生物界「分子擁擠」（molecular crowding）現象，希望以毒性低的材料作為水系電解液的穩定劑，以大幅減少電解液有毒鋰鹽或離子化合物的濃度。研究人員利用護膚霜和潤滑劑常用的原料「聚乙二醇」取代高濃度鋰鹽或離子化合物，在電解液擬造出「分子擁擠」現象，以抑制水分子活性，並成功研發新一款的鋰離子電池電解液。在低鋰鹽濃度下，新款電解液的穩定電壓視窗達到3.2伏特，能充放電300次，效能與傳統鋰電池及水系電解液鋰電池接近，但新款電解液不易燃燒，更為安全。盧怡君指出，以往的水系電解液鋰電池中有80%至85%重量都是鋰鹽，成本約為每公斤7美元至20美元，新款電解液將鋰鹽重量佔比降至30%至35%，成本可減至每公斤約1美元，即便宜八成半至九成半，而且棄置時更為環保。http://pdf.wenweipo.com/2020/05/15/a13-0515.pdf

Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K). Kapton is used in, among other things, flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments.The thermal conductivity of Kapton at temperatures from 0.5 to 5 kelvin is rather high for such low temperatures, κ = 4.638×10−3 T0.5678 W·m−1·K−1.[3] This, together with its good dielectric qualities and its availability as thin sheets have made it a favorite material in cryogenics, as it provides electrical insulation at low thermal gradients. Kapton is regularly used as an insulator in ultra-high vacuum environments due to its low outgassing rate.

物質貧乏時期，鄉下人冬季取暖很簡單：每晚弄些乾柴或莊稼的秸稈，在與土炕相連的土灶裏點燃了，煙火氣在土炕裏循環一周遭後從煙囪冒出，土炕便一陣比一陣溫熱。http://pdf.wenweipo.com/2020/12/05/b04-1205.pdf

糊火柴盒過去在很多地方，是沒有一技之長的人一項謀生的工作。很多家庭婦女每天做完家務，就到火柴廠把原材料領回家，熬一鍋漿糊即可操作，按工取酬。雖然收入微薄，但多少可以幫補一下家庭開銷。凡是糊過火柴盒的人，對火柴都會非常愛惜，因為深諳其中的艱辛，知道掙來的每一分錢都屬不易。有一陣子，街頭小青年扮酷的方式，是模仿電影《英雄本色》裏的「小馬哥」在嘴邊叼一根火柴棍。夏日夜晚，還有人把火柴直立抵在火柴盒的黑磷皮上，另一隻手猛力一彈，比賽誰彈得更遠。火柴在被彈飛出去的同時也被擦燃了，劃出一道火光，拖曳着一縷淡淡的青煙，或呈弧形，或直線形，一閃而過，飛快地消失在夜色之中。

死了或殺了樹，把土裏埋的那個整個兒根扒出來，這個「整個兒」就是我們通常說的木頭疙瘩。以前，鄉親們冬天圍在一起烤火，捨不得拿乾柴，就把一個半乾不乾的大木頭疙瘩放在中間，邊燒邊乾邊烤，一個木頭疙瘩能熏烤大半天。大個的木頭疙瘩塞不進鍋灶底，只有露天升起大鍋灶和烤火時才能用。秋冬不忙時，鄉親們就上山扒此前沒空扒的木頭疙瘩。扒木頭疙瘩相當費勁。一個半人高的鮮木頭疙瘩少說得一二百斤，木頭疙瘩上的粗根細根四處亂扎，像很多有力的觸角深鑽進周邊的泥土裏。從粗細的樹根間掏淨土石，截斷追不到盡頭的根，挖了刨晃了撬，扒出這樣一個木頭疙瘩至少得一兩天，一兩個星期扒不出來的情況也有。那次回家，父親正在劈柴禾。剛化淨雪，地上還很潮濕。我建議父親等幾天再劈，那梨樹枝約碗口粗，劈裂兩三半，用鋸截成二十厘米左右的小段並不算太難。父親說閒着沒啥事，多劈些柴禾攢起來，陰天下雨時用。http://pdf.wenweipo.com/2021/01/13/a20-0113.pdf

由墨西哥一間設計公司發明的Agrodome（圖），是一種透明溫室模塊。農民只要在播種後把它依序插在田間，就可為芽苗提供保護。Agrodome大小為一平方米，頂部是個漏斗，可以收集灌溉得來的水分和雨水，再導入土壤深處，方形的頂部另留有氣孔，有助通風。隨着幼苗長大，農民可以逐步拉高Agrodome，直至農作物成長到不需保護為止。https://orientaldaily.on.cc/cnt/china_world/20201215/00180_034.html


南韓科學技術研究院的高級複合材料研究所，早前研發出一種採用亞麻籽油微膠囊技術的手機屏幕，最快能在20分鐘內自動修補95%的屏幕裂痕。團隊將亞麻籽油微膠囊與含硅膠化學成分的聚二甲基硅氧烷混合，再將混合溶液放到手機用的透明聚醯亞胺（CPI）薄膜上及讓其乾燥。當薄膜被壓到開裂點時，微膠囊的表層也會裂開並釋出亞麻籽油，暴露在空氣中的亞麻籽油會硬化成透明固體，從而填充和修復裂縫。實驗發現，硬化過程在攝氏25度的室溫條件下，需時數小時修補裂痕，惟將其加熱到攝氏70度或暴露在紫外線下，可加快修補進程，研究人員相信該材料有望廣泛應用於其他電子器材。研究已發表在《複合材料B部分工程》期刊。https://orientaldaily.on.cc/cnt/china_world/20201230/00180_041.html

豬頭豬蹄到處是毛，且不少匿於耳孔、趾縫等難以下手地帶。怎麼辦呢？但見父親不慌不忙地找來幾顆柏油塊，放在廢棄的臉盆裏架火燒煮成液狀，再用廢棄的勺子舀上一勺，灌到有毛的部位，待滾燙轉溫，用右手拇指和食指鉗住柏油邊緣，隨着「哧啦」一聲響，柏油像膏藥貼一樣被迅捷地揭掉，原先覆蓋在柏油下面的一大片密匝匝的鬃毛不翼而飛了！看着我們姐弟驚異的神情，父親一邊繼續先前的動作，一邊講解道：「柏油具有很強的吸附性，將它灌到有毛的地方，它會像吸鐵石一樣把毛牢牢地吸附住。但是，揭柏油必須掌握火候，如果下手早了，沒有將液化轉換成固化，毛髮無法獲得完全吸附；如果下手晚了，柏油凝固到豬的皮膚上，無法揭掉，只能用鐮刀刃一點點往下割，不僅費時費力，而且效果不好。」http://pdf.wenweipo.com/2021/01/22/a23-0122.pdf
