+**Jessica Stanley's Stitch Synth**
+I saw [Jessica's work](https://class.textile-academy.org/2019/jessica.stanley/projects/00final-project/) at the last Fabricademy expo in Amsterdam. Super nicely done. 
+
+I also really liked her experiments with tesselation in the Textile as Scaffold week. The slow movements the textile creates are really nice to watch. 
+
+And also her voronoi for [computational couture](https://class.textile-academy.org/2019/jessica.stanley/assignments/week07/) are so cool. She printed these shapes on stretchy fabric, making the textile pull itself into a 3D shape. 
+
+And the pleat switch and this sensor below. OMG Jessica  stop it nowwww I'm totally fangirling your fabricademy page. This makes me think I will really enjoy the electronics work in the next few months.

+### Go big or go home: drag performers and other style queens
+This is something I've been obsessed with for a long time. I think the innovative ways of thinking about the malleability and unstable nature of the body and gender is super interesting and made me fall in love with this art form. I do it myself sometimes too :) No RuPaul quote is lost on me (we're all born naked and the rest is...you know the rest). I'd love to take as many assignments as possible closer toward something that might be applicable in the context of the art of drag to develop into a larger project later. I imagine eco-aware drag could be a very interesting avenue to explore. In the meantime, I'll summarize as: go big, or go home.

One reason why I like this is because I imagine picking cleverly from waste materials will allow for a lot of cool designs. They can also be combined with electronics perhaps?

 ## Assembling
 
-In the end I tinkered a lot with the modules to see how I could combine them to create various shapes. I made big sheets combining different modules, by going bigger or smaller per row to understand what kind of shapes it would create. I didn't quite realize how long it was going to take me to create a big surface, and I ran out of material so I settled on a garment I could make with the amount of modules I'd cut. I thought that the curvy shape it was making could work really nicely as a sort of necklace/choker/harness that follows the curves of my neck and shoulders.

 Our first explorations involved very simple ingredients: thermovinyl, parchment/baking paper and heat. By cutting out airchannels by hand from baking paper, and creating little pockets by welding together two parts of vinyl with heat (using a heat press or iron), we were able to explore some movements and dynamics. Two layers of vinyl are welded together unless there's baking paper between the layers. Where there's baking paper, air can circulate (the baking paper are the air channels). It's not very straightforward to guesstimate what these shapes will do though! So it was good to explore a little first. These are the basics as described by Adriana in the lecture:

docs/files/example_glycerine.md

+*Note: the ingredients section is still under development, this is an example of what the entries here will look like.* 
+
+# 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.

+
+# 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

+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.
