Optional: use a diluted natural dye instead of water in the same amount for a colored plastic. + - Put the oil, alginate and glycerine in a blender and add a dash of the water. Blend into a thick and homogenous paste. Then add the rest of the water and blend again (this is to avoid lumps). + - Leave the mixture overnight to allow the bubbles to come to the surface and pop. + - Make the calcium chloride solution by dissolving 10 gr in 100 gr hot water. Put some in a spray bottle and store the rest in a jar: this is your calcium chloride bath. - - Weigh your ingredients - - Prepare the mold and find a place where you can leave it for a while, ideally near an open window where there's air flow. - -1. **Mixing and dissolving the ingredients** - - bring the water to the boil - - optional: add natural dye if you wish to use color - - add the glycerine - - add the gelatine - - keep the temperature below 80 degrees celcius while stirring *very very slowly and gently* to avoid making bubbles. I prefer a simple spoon to do this, not a whisk. - -1. **Cooking the ingredients** - - - Simmer and slowly stir the mixture between 60-80 degrees celcius for at least 20 minutes or up to an hour. Turn it lower when bubbles appear: you don't want the liquid to move, don't boil it. This sample has some bubbles due to vigorous mixing. - - Longer cooking time allows more water to evaporate. You will get a thicker liquid. To cast larger volumes and solids with this recipe, evaporate a lot of water, until it's very thick. - -1. **Casting** - - - Let the liquid cool for a couple minutes until it gels a little but is still liquid and pourable. - - Cast into the mould slowly to avoid bubbles - - Pour from the middle and hold still, let the liquid distribute itself. - - Put the mould away to dry in a cool place with lots of air flow (like near an open window). A warmer place might speed up the drying process but also allow bacteria to grow faster and can result in fungal growth. - - If the mould has a removable base, remove it after 4-8 hours and put the mould on its side to allow air flow from both sides. - - When using a flexible mould: let it dry without releasing to keep the form as much as possible. The resin will likely shrink and release itself from the mold. If it feels cold to the touch it is still drying. If you are using a rigid mold: release after 4-8 hours and dry flat. +1. **Extruding** + - prepare the work space by putting out your calcium chloride bath and spray, an empty jar to wrap the string around, a syringe and your alginate mixture. + - fill the syringe with about 50 ml alginate plastic + - extrude the alginate plastic into the calcium chloride bath, try to extrude continuously and uninterupted to created an even, long string. Repeat this process to make more strings. + - leave the string in the bath for a few minutes and then rinse in some tap water. + - the strings will be a bit curly at this stage. Wrap them around a jar to create a spool and stretch them out a little. + - keep an eye on them the first day, the stretch might break the film on some points. Spray some extra calcium chloride to close the leaks. + - Let it cure until totally dry, you can take the string off the jar if you want to stretch them out into long straight strings. ### Drying/curing/growth process -- Mold depth: 7 cm (filled up until 2.5cm high) +- Mold depth: N/A - Shrinkage thickness: 20-30 % -- Shrinkage width/length: 20-30 % +- Shrinkage width/length: N/A **Shrinkage and deformation control** -Letting it dry up to ten days to get to the final form.

In 1500 BC, people in Egypt were already using glues based on gelatin, casein and albumin for furniture constructions. Gelatin casting as a technique has also been used in production of jelly-based foods such as aspic, jelly desserts and candy. +Alginate plastic is used a lot in molecular gastronomy, for (reverse) spherification that was patented by William J. S. Peschardt in the 1940s and popularized in the molecular cuisine popularized by Adrian Ferra from restaurant El Bulli. Alginate plastics are also used a lot in molding and casting of dental technology industry. **Needs further research?** Not sure ### References this recipe draws from -- **Bioresin (gelatin) Recipe** by Cecilia Raspanti (Textile Lab, Waag), Fabricademy Class "Biofabricating", 2019, [link](https://class.textile-academy.org/classes/week05A/). -- **The Bioplastics Cookbook: A Catalogue of Bioplastics Recipes** by Margaret Dunne for Fabtextiles, 2018, [link](https://issuu.com/nat_arc/docs/bioplastic_cook_book_3) - -### Known concerns and contestations\* +The alginate recipe is a modified version of: **Flexible Bio-plastic Alginate Recipe** by Cecilia Raspanti (Textile Lab, Waag), Fabricademy Class "Biofabricating", 2019, [link](https://class.textile-academy.org/classes/week05A/). -Needs further research +The technique of alginate string extrusion is a variation on the experiments documented by Carolina Delgado (2020) in her Fabricademy [project page:](https://class.textile-academy.org/2020/carolina.delgado/projects/final-project/#netting) -Gelatin is an animal-based ingredient.
