1. Preparation
   • 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.
2. 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.
3. 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.
   • Longer cooking time allows more water to evaporate and will dramatically reduce shrinkage of the casted object. You will get a thicker liquid. To cast larger volumes and solids with this recipe, evaporate a lot of water, until it’s very very thick. Sometimes it’s worth reheating and melting scraps, they’ve already dissipated a lot of water and result in nice castings.
   • If froth appears on top of your liquid and doesn’t go away, you can use a coffee filter to absorb it by covering the surface with it and then taking it off. In cooking this is called a cartouche, you can also make one from kitchen paper. Take a round coffee filter that fits into your pot. Absorb additional froth using some kitchen paper.
4. 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.
