+# GLYCERINE 
+
+(glycerin, glycerol)
+
+**What is it and how is it produced or sourced?**
+
+Glycerin is a sugar alcohol derived from animal products, plants or petroleum (as a by-product of biofuel). It can also be obtained from microalgae oils, and it can be recovered from used cooking oil. Not all of these are equally common however.
+
+Vegetable glycerin is made by heating triglyceride-rich vegetable fats — such as palm, soy and coconut oils — under pressure, using heat, and/or together with a strong alkali, such as lye, which causes the glycerin to split away from the fatty acids and mix together with water, forming an odorless, sweet-tasting, syrup-like liquid. During WWI and WWII, glycerine was produced by fermentation as well, but there routes have not been under-utilized by industry because it could not compete with chemical synthesis from petrochemical compounds. 
+
+With necessary precaution you can make glycerine yourself.
+
+**What are its possible functions in biofabricating?**
+
+*e.g. plasticizer, filler, colorant, PH modifier, mordant, solvent, release agent, curing agent, softener, and so on*
+
+Vegetable glycerin softens and hydrates human skin, increasing smoothness and suppleness. It is often used in skincare and also works as a laxative. It has antimicrobial and antiviral properties. It has many possible functions (as many as 1583 uses have been listed by the Glycerine Producers Association in 1945), but here are a few that are particularly useful in biofabication:
+
+- plasticizer for more flexible bioplastics
+- moisturizer or softener in fish leather tanning (e.g. fish leather)
+- additive for soap bubble mixes
+- solvent for	 pigment extraction (not documented here)
+
+**Processing information**
+
+Dissolves in:	cold and hot water, and alcohol
+PH value:		5
+
+**Selecting the right type**
+
+*How do you know if you are getting the right type (in nature/at the shop)? Or can you use any? For example, carbonate and bicarbonate soda are significantly different, but you may find it is referred to as "soda"*
+
+Look for glycerin(e) or glycerol. In the U.S., glycerin(e) is a brand name for a purified variety of 95%, with glycerol being the principal component. In Europe, glycerol is more widely applied interchangeably. Smaller bottles are often more expensive. You might need to contact the supplier about the origins of the product if you want to know before. Choose a plant-based glycerine, it should state on the label what it is made of.
+
+## Local abundance
+
+**Where are you located?**
+
+Rotterdam, the Netherlands
+
+**Can this ingredient be found in nature there?**
+
+No, it is a processed ingredient. But it can be produced almost anywhere. Try to find a vegetable-based glycerine that is produced regionally or locally. 
+
+**If not, please describe or list local suppliers and price**
+
+In the Netherlands, Orphi is an affordable vegetable-based glycerin brand. This ingredient is best purchased online, in 1 litre bottles. 
+
+and costs about 6 Euros per 1000 ml (1L). 
+
+**If store-bought, find out where the ingredient was produced. How far is the production source from where you are?**
+
+In Portugal: less than 2000 km from site of use
+
+##Eco-compatibility
+
+*Type and amount of energy used to produce this ingredient, e.g. does it require a lot of water, heat, chemicals?*
+
+The production of glycerine requires heat and pressure, and sometimes strong alkali, like lye. It it also a product of fermentation processes but this is less efficient and cannot yet compete with synthetic methods. 
+
+**Toxicity**
+
+*Is this ingredient toxic to humans/animals?*
+
+No. But some people have an allergic skin reaction to vegetable glycerine. 
+
+**Distance from origin to site of use** 
+
+*In which region(s) of the world is this produced? Is it related to specific natural contexts or industries (e.g. near sea or rivers, in hot humid climates).*
+
+Depends on the way it is produced, but there are many methods. Needs further research.
+
+**Shelf life** 
+
+*Look up shelf life & expiry date, but also use of senses to check: can you see when it’s off, can you smell it?*
+
+Shelf life: years if unopened, check smell
+
+**Vegan**
+
+*Is it made without the use of any animal products?*
+
+Yes/No, depends on the method of production
+
+
+**Is this a by-product is it found in a waste stream?**
+
+*Is this ingredient a by-product or does it come from waste streams*	
+Yes, it *can* be a by-product of biofuel production and/or soap production, but this is not always the case. 
+
+**Renewable**
+
+*Can this resource be naturally replenished on a human timescale?*
+
+Yes
+
+*What do you know about how long it takes for this ingredient regrow?Which plants/micro organisms grow this ingredient? How long does it take them to regenerate? Under which conditions?*
+
+- Glycerine from soy: byproduct of soybean biodiesel industry
+- Glycerine from palm oil: kernels of palm fruits are harvested all year round. But is also connected to deforestation issues.
+- Glycerine may be a byproduct from soap manufacturing 
+
+Needs more research
+
+
+## Cultural & historical information
+
+*Historically, what were the uses of this ingredient? In which contexts were these uses discovered? When? By whom? How did it travel to other places?*
+
+Glycerine is closely linked to the life processes themselves, and is a component of all living cells. It occurs naturally in wine, beer, bread and other fermentation products of sugar and grains. It is found in nature as triglycerides (a combination of glycerine and fatty acids that make up almost any vegetable and animal fat or oil). 
+
+Glycerine was discovered by accident in 1779 by K.W.Scheele. The Swedish chemist was heating olive oil and a lead monoxide, and he published his findings in 1783 in the Transactions of the Royal Academy of Sweden. His method which he called "the sweet principle of fat" was renamed into glycerine (from the Greek γλυκύς or glukus which means sweet) by M.E. Chevreul, who patented a new production method in 1823. Glycerine was of no economic significance until Alfred Nobel found the first worldwide technical application for it: for his invention of dynamite in 1866. It is said to have fueled industrial development of chemicals. 
+
+##Concerns 
+
+**Describe how this ingredient has been or might be contested. What are the concerns and dilemmas? Which arguments are put forward?**
+
+*may be cultural, health-wise, ecological, social, cultural, political, economical arguments*
+
+The purity of glycerine is essential for some applications (e.g. in chemistry, cosmetics, and food grade glycerine). With the increase in biofuel production, the production of glycerine grew as well. Purifying glycerine however is a particularly energy intentive part of the production process. Perhaps further research could be done on the required purity of glycerine for use in bioplastics.

+Wikipedia
+
+The first use of gelatin in foods is documented in the 15th century in medieval Britain, where cattle hooves were boiled for extended periods of time to produce a gel. This process was laborious and time-consuming, confined mainly to wealthier households.[43] The first recorded English patent for gelatin production was granted in 1754.[43] By the late 17th century, French inventor Denis Papin had discovered another method of gelatin extraction via boiling of bones.[44] In 1812, the chemist Jean-Pierre-Joseph d'Arcet(fr) further experimented with the use of hydrochloric acid to extract gelatin from bones, and later with steam extraction, which was much more efficient. The French government viewed gelatin as a potential source of cheap, accessible protein for the poor, particularly in Paris.[45] Food applications in France and the United States during 19th century appear to have established the versatility of gelatin, including the origin of its popularity in the US as Jell-O.[46] From the mid 1800s, Charles and Rose Knox of New York manufactured and marketed gelatin powder, diversifying the appeal and applications of gelatin.[47]
+
+Culinary uses
+Eggs in aspic
+
+Probably best known as a gelling agent in cooking, different types and grades of gelatin are used in a wide range of food and nonfood products. Common examples of foods that contain gelatin are gelatin desserts, trifles, aspic, marshmallows, candy corn, and confections such as Peeps, gummy bears, fruit snacks, and jelly babies. Gelatin may be used as a stabilizer, thickener, or texturizer in foods such as yogurt, cream cheese, and margarine; it is used, as well, in fat-reduced foods to simulate the mouthfeel of fat and to create volume. It also is used in the production of several types of Chinese soup dumplings, specifically Shanghainese soup dumplings, or xiaolongbao, as well as Shengjian mantou, a type of fried and steamed dumpling. The fillings of both are made by combining ground pork with gelatin cubes, and in the process of cooking, the gelatin melts, creating a soupy interior with a characteristic gelatinous stickiness.
+
+Gelatin is used for the clarification of juices, such as apple juice, and of vinegar.

+#LINSEED OIL
+
+Raw Linseed Oil dries very slowly, taking weeks to fully cure. You should limit its use to the insides of wood gutters, chopping blocks, sawhorses, and other items exposed to the elements where drying time is not a consideration. Slow drying is a mixed blessing. For oil-based paints slow drying is a benefit since this allows the paint to “level” itself, giving a smoother finish with fewer brush marks. The best looking paint jobs are invariably oil paint jobs. However, when used as a wood preservative for items that are handled or walked on, such as tool handles, furniture, or wood decks, long drying times are undesirable, so Boiled Linseed Oil should be used.
+
+So: raw = longer drying time but less additives
+

+
+
+
+Linseed oil and related oils are important components of useful products used in oil paints and related coatings. Linseed oil is rich in di- and tri-unsaturated fatty acid components, which tend to harden in the presence of oxygen. This heat-producing hardening process is peculiar to these so-called drying oils. It is caused by a polymerization process that begins with oxygen molecules attacking the carbon backbone
+
+https://en.wikipedia.org/wiki/Triglyceride#Industrial_uses
+
+
+A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air. The oil hardens through a chemical reaction in which the components crosslink (and hence, polymerize) by the action of oxygen (not through the evaporation of water or other solvents). Drying oils are a key component of oil paint and some varnishes. Some commonly used drying oils include linseed oil, tung oil, poppy seed oil, perilla oil, and walnut oil. Their use has declined over the past several decades, as they have been replaced by alkyd resins and other binders.
+
+Since oxidation is the key to curing in these oils, those that are susceptible to chemical drying are often unsuitable for cooking, and are also highly susceptible to becoming rancid through autoxidation, the process by which fatty foods develop off-flavors.[1] Rags, cloth, and paper saturated with drying oils may combust spontaneously (ignite) after a few hours as heat is released during the oxidation process.

+#INGREDIENTS & CONSUMABLES
+
+![](../images/ingredients-2.jpg)*Some ingredients you'll need, Loes Bogers, 2020*
+
+The recipes listed on this website can be used as a starting point for material makers in the Netherlands and around. Consider per ingredient if this is something that is locally abundant in your area. If not, try finding something that could substitute that ingredient to make it your own, and follow the local natural resources around *you*.
+
+With these 40 ingredients you can list all the 25 recipes suggested as a material archive starter, with a suggestion for a local supplier and approximation of the cost per unit. Check out the tools section as well, this list contains disposables only. For under € 500 you can purchase all the ingredients listed below, and most will last many rounds of experiments. The prices listed per material sample in the recipe section are based on the prices below. Of course it is possible to buy smaller packages of most ingredients, this will be *relatively* expensive, but wise if you are planning to just try it out.  
+
+
+##Locally abundant ingredients to collect 
+
+Selecting the 24 recipes to start with in the Netherlands were mostly motivated by what is abundant here locally. So the ingredients listed here involve food waste and byproducts that ideally should not be purchased, but sourced by accessing waste streams or collecting leftovers. If you start out doing this from home, it really helps to collect nice glass jars, pots and bowls for collecting and drying food waste. Remove the labels and give them a nice place e.g. in a window where you are reminded and where you can keep an eye on them as they dry.
