If the paper becomes red/pink the PH is 2-4, purple is 5-7, blue is 8-9 and green/yellow is PH 10-12 approximately. See also [link](https://www.thoughtco.com/make-red-cabbage-ph-paper-605993)

Ink has even been made of cigarette butts!
### Cultural origins of this recipe
##ORIGINS & REFERENCES
**Cultural origins of this recipe**
The anthocyanin in red cabbage is what makes it PH sensitive, and is why it changes color as you modify it with acidic or alkaline solutions.
Dyeing fibres with vegetables is an ancient craft: the earliest dyed flax fibers have been found in a prehistoric cave in the Republic of Georgia and date back to 34,000 BC. Before the invention of synthetic dyes starting in the mid-19th century, all fibres and textiles were dyed using organic and inorganic materials as *dyestuff:*like clay, plants, metals, bark, funghi, flowers, insects, seeds, and fruit and vegetables (and even the blood of animals). The development of new, strongly colored synthetic dyes followed quickly, and by the 1870s commercial dyeing with natural dyestuffs was disappearing: synthetic dyes were more stable, more colorfast and in many cases could be done at lower cost than the overal costs of natural dyeing processes.
**Natural dye revival(s)**: there have been revivals in plant dyeing as a crafts technique in the 1970s, with enthusiasts publishing books in layman's terms that became popular again today. These recipes might be natural, but may still use heavy metals as mordants. More recently, in tandem with the growing concern for pollutions caused by textile dyeing at industrial scale, which involves lots of chemicals, heavy metals that end up in drinking water, on worker's bodies and in the environment. It also requires a lot of water due to the rinsing needed to wash all the chemicals out, and to achieve colorfastness. Next to bacterial (and fungal) dyes, plant-based dyes are investigated as non-toxic, renewable alternatives to synthetic dyeing processes. Some natural dyes, like madder (for red hues) has been developed into a powder recently in such a way that it is fit for textile dyeing at an industrial scale.
It's somewhat unconventional to use more ephemeral dyes such as this one as textile dye. It's not very lightfast and extremely chemically unstable (the PH sensitivity). But some are worth exploring by designers who are able to celebrate these dyes' vividness and ability to change, fade and surprise. It is unlikely that natural dyes will provide the color fastness and ability to dye synthetic textiles like synthetic dyes can, but perhaps what we need much more urgently is an attitude change to color in textiles and clothing?

### Known concerns and contestations
###Copyright information
Cabbage can be found in abundance in many countries (including the Netherlands). It is not a hugely popular vegetable but still very common. Try to get red cabbage as food waste instead of buying it fresh. Dye materials should not compete with food.
This recipe may be considered to be part of the public domain.
The color purple this dye or ink creates is quite contested. Historically, purple (and especially the socalled Tyrian purple, made of the secretions of sea snails) was considered to be the color of power, reserved for kings and queens and the like. It is also one of the colors that has historically ben rather expensive to produce as it required significant amounts of (often expensive) resources to generate intense and colorfast dyes using natural resources. Due to it's changing nature, red cabbage dye would not be considered an option worth considering for current textile dyeing practice. But perhaps its humble background and volatility make it the perfect everywoman's purple. Could it be instrumental in conveying the temporary luxury of purple textiles? Perhaps it is sufficient to be queen for a day?

## Variations on this recipe
###Variations
- Add natural *alcohol-based* colorants to dye the fish skins (e.g. turmeric, hibiscus, or grated beetroot/red cabbage: submerge in alcohol and shake every hour for a day).
- Other softeners to try: leather balm, coconut oil, other oils
- Putting a fish skin in the oven for 5-10 minutes at low heat (70 degrees Celcius), it turns highly flexible.
- Make a suede-like soft leather by tanning the fish skins in boiled linseed oil. Add a rock or something heavy to create a lot of friction when shaking the container. Take the fish out to dry, repeat if it is not soft enough. There are several linseed oils out there. Raw is often used for outdoors use and contains less chemicals and petrol-based drying agents but dries a lot slower and can stay sticky. The technique used with raw linseed oil is similar to they way fishing nets are impregnated to stand the harsh conditions at sea.
### Cultural origins of this recipe
##ORIGINS & REFERENCES
**Cultural origins of this recipe**
Traditional tanning techniques are centuries old and have been practiced by peoples in most of the Nordic countries (Denmark, Finland, Iceland, Norway), the Joepik in Alaska, the Nanai in Siberia, the Inuit in Canada and Greenland. It is practiced all around the world (e.g. along the Nile in Kenya, in Mexico and in Australia). Originally, the involved tanning acids from e.g. oak and chestnut bark, urine, or alternatively with egg yolk and vegetable oil and then cold-smoked over fire to make it water-proof (also prevents mold and bacteria growth). Alutiiq artist June Simeonoff Pardue has been credited for this non-traditional tanning process with alcohol and glycerine. Fish skin can also be cleaned and dried without tanning.

- The process is smelly, but the finished product is nearly odorless if done well
- This material is animal-based (but the production & tanning process is significantly eco-friendlier process than those of e.g. cow hide.
- Denatured alcohol is harsh on skin but not dangerous, don’t use on open skin however.
- Choosing fish that are not locally abundant or known to be overfished is considered problematic. Try to find fish from sustainable fishing industries, and fish that is in-season, or the bycatch from local fishing industry.

## Material properties
### Comparative qualities
Pounded paper made from flower fibres results in a thin but very strong paper. It is more rigid than for example office paper and has more texture. You can see all the details of the fibres used.
Blended paper (especially the ones made with stems) are more brittle and have even more texture and a rough feel. Somewhat like pressed paper waste composites (such as the ones used for fruit and vegetable packaging), but more rough to the touch.

### Description
##GENERAL INFORMATION
This is a thin translucent bacterial cellulose material resembling paper, made of a dried 3-5mm kombucha SCOBY.
This is a thin translucent bacterial cellulose material resembling paper, made of a dried 3-5mm kombucha SCOBY. The kombucha paper is translucent, sometimes with visible traces of the yeast and bacteria strings. The color varies with the liquid the SCOBY was grown in. It is comparable to parchment paper or tracing paper in terms of sound and translucence, but has less uniform shape, thickness and color. Yeast strains that may be browner etc, give the finished product a type of "grain" like wood or leather might have.

###Variations
- The same process can be used to create more leather-like sheets. Follow the exact same recipe but use a SCOBY that grew into 10-15 mm thickness instead of 3-5mm.
- The kombucha paper takes on the shape it dries in, try drying the paper on top of a mold to let it dry and contract into a 3D shape. Use vaseline as a release agent.
- Dye the pellicle before oiling and drying, by dipping it into a concentrated natural dye. It takes on dye quite well.
- Coconut oil as post-treatment has also been suggested. Rub it into the wet kombucha pellicle. Without a sealant, the kombucha could become sticky if worn in the rain. Full water resistance can be achieved if using acrylic or oil based sealers, but then the material is no longer safely biodegradable.

##ETHICS & SUSTAINABILITY
Because the SCOBY scan regrow itself infinitely with a bit of water, tea and sugar, and can be composted, it's a relatively uncontroversial material but still requires resources and more importantly, a lot of time. Especially in colder climates it is tempting to use heating to speed up the growth. As a material, it is still very much in development.
Additives and post-treatments like boiled linseed oil and turpentine are not necessarily eco-friendly products. Chemicals are added to boiled linseed oil to make it dry quicker than raw linseed oil for example. There is room for improvement in the area of techniques and compounds to make the pellicles stronger and more durable.

##ORIGINS & REFERENCES
**Cultural origins of this recipe**
Kombucha is an ancient Chinese fermented drink made of sweetened green or black tea and yeast and bacteria cultures. It is said to have originated in Manchuria (now Northeast China) and was hailed for its curing qualities. It spread across Asia and later also Russia. It was brought to Europe with the expansion of trade routes in the 1900s where it gained popularity (most notably in Germany and Switzerland, as "Kombuchaschwamm" due to alleged health benefits comparable to those of yoghurt. Initially it was brewed by enthousiasts sharing the mother SCOBY or mushroom with a grassroots community of fermentation lovers, both in Europe and the U.S. Commercial enterprises started to pop up from the mid-90s onwards and recently one of the big kombucha brewers KeVita was purchased by PepsiCo for $200 million.

### Cultural origins of this recipe
##ORIGINS & REFERENCES
**Cultural origins of this recipe**
Before synthetic dyes were discovered in 1856, you would have had to use natural dyes which were made from animals and plants. The most common - and intense - being madder for red, and indigo for blue. Madder came from the roots of 35 species of plants (Rubia Tinctorum) found in Southern Europe and West-Asia. It has been found in the cloth of mummies and was the first dye to be used as camouflage. It was a popular dye madder in the Middle Ages and is mentioned in the Plichto van Gianventura Rosetti from 1548. Madder was brought to the south of the Netherlands and Flanders around 1300 where the clay soil was optimal for madder cultivation. This led to a thriving local industry - and for a while a monopoly - for madder production (NL: "meekrap") deemed the best quality in Europe .This was the case until *garancine* the synthetic counterpart for alizerine was discovered and gained in popularity around 1870.

##ETHICS & SUSTAINABILITY
Compared to red pigments coming from the synthetic garancine, madder is less ecologically taxing. It doesn't require the sulphuric acid was used in the synthetic product. The plant can easily be multiplied and can be harvested for dyeing only after 2-3 years. The process is deemed rather labour intensive (require a fair amount of weeding and fertilizing). The roots need to be dried, which happens naturallly in sun light in warme climates. Heat needs to be generated in cold areas such as northern Europe. In comparison to commercial synthetic dyes, it is surely an improvement.

Flexible leather-like sheet made from overripe mangos. The material is thin but emulates the feeling of leather quite well but feels a little dryer to the touch than leathers used in most clothing items and accessories.

###Ingredients
* **1 Overripe mango - with skin** get these as waste from the market, they can have dents and bruises it doesn't matter. We will dehydrate the mango until it becomes leather-like.
* **Potato starch - 15 g** functions as the polymeer (makes the mango puree harder)
* **Glycerine - 15 gr** functions as plasticizer (makes it flexible).
* **White vinegar - 15 gr** vinegar is almost always added to starch-based biopolymers to change the molecular structure of the starch, making it stronger and more workable
* **Salt - 5 gr** as a preservative and stabilizer.
* **Vegetable oil - 1 tbsp** as a release agent for the mould.

### Description
##GENERAL INFORMATION
Recipe for alkaline and acidic PH modifiers to be used with natural dyes and inks (water and alcohol-based), and PH test strips made with red cabbage dye or ink.
PH modifiers can change the original color to become brighter, duller, or even go all the way from purples to greens and blues. Alkaline tends to make colors PH sensitive natural dyes "colder", while acidic dyes create warmer shades. Acidic and alkaline modifiers have an especially strong effect on dyes made of vegetables that contain *anthocyanin* such as red cabbage, hibiscus, blueberry.
### Physical form
Less precise than litmus paper but precise enough to indicate acidity, neutral or alkaline PH. Might lose its properties as PH indicator over time (needs further research).

- It is useful to know and record this information. For example, if a bioplastics mixture is very acidic (e.g. the starch-based plastics that contain vinegar), it will modify the color of a PH sensitive dye when you add it. Knowing this before hand will help you pick your dyes accordingly.
- Also testing the PH values of water can be useful. In some recipes you might need to know if your tap water is alkaline or not so you can assess whether you need to offset it by adding some vinegar or other acid to your recipe (e.g. for growing kombucha SCOBY).

### Cultural origins of this recipe
##ORIGINS & REFERENCES
**Cultural origins of this recipe**
Red cabbage juice has been known to be a PH indicator (origins unknown) and is a favourite for science experiments in education.
A historically more well-known PH indicator however, is the *litmus test*, a procedure ascribed to Spanish alchemist, astrologer and phycisian Arnaldus de Villa Nova, around 1300. The term litmus comes from an Old Norse word meaning "to dye or color." As such it is strongly associated with practices of alchemy, a precursor to contemporary science that has long been ridiculed for its esoteric philosophy, magic and quest to turn lead into gold. Eventually historians of science acknowledged alchemy for laying groundwork for science with many of its practical and experimental applications and techniques, such as litmus.

### Description
##GENERAL INFORMATION
Melted PLA (poly lactic acid based on cornstarch that is often used as 3D print filament) has a beautiful glossy shine (if not pressed), it is strong, waterproof and very heat resistant: it maintains the same properties as before.
### Physical form
These sheets and rosters are strong and light and more dense than most PLA prints (because usually a partial honeycomb in-fill is used to create 3D shapes with a printer, it is usually not solid PLA). It's very glossy, like polycarbonate, acrylic sheets, or shiny PVC clothing.

### Cultural origins of this recipe
##ORIGINS & REFERENCES
**Cultural origins of this recipe**
**About the material**: Polyactic Acid (PLA) was invented as early as the 1920s by the Wallace brothers, the same people who invented nylon. They searched for a more environmentally friendly pastic but its uptake grinded to a halt because it was too expensive for commercial use. Many bio-based plastics continue to be more expensive than their petroleum based alternatives. Patrick and Sally Gruber discovered how to create PLA from corn in their kitchen stove in 1989. Their technique reduced the cost of PLA production greatly.
In recent times, it is strongly associated with 3D printers (CNC machines that extrude thermoplastics into a 3D shape defined in a digital design (using stereolithography). It was hailed as the biodegradable alternative for ABS (Acrylonitrile Butadiene Styrene) filament, which is a derivative of natural gas and petroleum.
**PLA and bioplastics**: PLA is made of renewable materials, or biomass (like corn starch), which makes it a bioplastic. The difference with normal plastics is that it is not based on finite resources such as petroleum. The bioplastic PLA is also compostable, which means it an be turned into compost by microbes so it can be reabsorbed by nature, but only under "certain conditions": PLA degrades if it is in 55-60 degrees Celcius for at least 10 days. Not all bioplastics as biodegradable/compostable. Some, like bio-PET or bio-PP are chemically the same as their petrol-based counterparts even though they are made of renewable resources.

##ETHICS & SUSTAINABILITY
[Notes]
Strictly speaking, PLA is a **compostable** bioplastic. Something is compostable when it can break down into carbon dioxide, water, inorganic compounds and biomass in small pieces in about 90 days (in an industrial composting facility). It efffectively means it can be converted into good quality *compost* and when composted, acts as a beneficial fertilizer. However, it is important to note that composting does not always happen under the same conditions: for some plastics this requires special processes and facilities to do so, which may involves the use of more energy.
### This recipe draws together information from these other recipes
PLA for example needs to be composted at 55-60 degrees Celcius for 10 days: not the temperature of your average compost heap in the garden. This is done in industrial composting plants where the right air, microbes and temperature is monitored in **controlled environment** so the composting process can take place.
**Failed Print Recycling Revisited: Guitar Picks, Earrings, and More**, by Devin Montes on his MakeAnything Youtube channel, 28 April 2017: https://www.youtube.com/watch?v=42c8go9A7HQ
Most of the other bioplastics recipes here, like the gelatin-, agar- and starch-based bioplastics will compost under almost any conditions (also in your backyard): they don't require a lot of heat and almost any microbes will do the job in composting these. As such they are suitable for *home composting* under loosely controlled conditions.
### Known concerns and contestations
Generally speaking, although highly compostable materials can return to the earth, it has been argued that this is still a waste of energy: the energy used to create the complex polymer. It is useful to consider if re-use is not better than composting for materials that allow it (e.g. PLA, but also the gelatin-based bioplastics described here). There are no simple "silver bullet" solutions to the plastic problem, but we keep searching.
Needs further research
It has been suggested that *recycling* Poly Lactic Acid plastics (PLA) is a better end-of-cycle alternative than combusting/composting.
Although this is not a compostable bioplastic (it is biodegradable but requires special processes to do so, and involves quite some energy). It has been suggested that recycling Poly Lactic Acid plastics (PLA) is a better end-of-cycle alternative than combusting/composting in this case.
Biocompostable is not the same as biodegradable. A *biodegradable* product *may* be broken down by microorganisms (eventually, but this can take much longer than 90 days and still be called biodegradable) but this does not necessarily imply that the product can be converted into good quality compost that is good for the soil and plants. It just means it will not harm the environment once degraded. TÜV Austria in Belgium provides several certifications for different kinds of compostable plastics: they describe the distinction between industrial and home composting on their website, but also have separate certificates form materials that are compostable in the soil and in water. Their website is a good resource for disambiguation.
### Sustainability tags
Lastly, even though some plastics can be composted, it doesn't mean it happens. At the moment it is not cost-effective enough for most recycling plants to offer this service, so the compostable plastics end up getting mixed up with the PET, PE and PP's and can contaminate the waste stream, weakening the properties of recycled plastics.
Conversely, there's an unwillingness amongst professional composting plants to accept bioplastics, because they believe comsumers might recycle bioplastics that are not compostable, which contaminates the quality of the compost that is to be reused as a fertilizer.
- Renewable ingredients: yes (cornstarch)
NOTE: this information is based on European standards and might be different for other countries.
**Sustainability tags**
- Renewable ingredients: yes (plant starch from corn, beets, sugar cane)
- Vegan: yes
- Made of by-products or waste: yes
- Biocompostable final product: no
- Biocompostable final product: yes, but only in *special* composting facilities (requires 55-60 degrees Celcius for at least 10 days). Hence the recycling recipe.
- Re-use: yes, it can be re-melted endlessly as long as the PLA is not combined with other materials in a composite.
Needs further research?: Not sure
Recycling PLA with PET plastics contaminates the waste stream.
