You can make this recipe in batches. Try varying the quantity of turmeric or water in the recipe to get a weaker or more concentrated solution. You can use the dye straight away. You could also store it in a clean jar or glass for up to 3 days at room temperature. You can keep this in the fridge if you want to keep it longer. You can even freeze the dye once it is at room temperature. You substitute this dye for water in a biomaterial recipe.
