Hi, welcome to Iornlak Science where we teach you how to make the perfect art substances. Today were going to teach you how to make and apply your own wheat paste. This sticky substance is like a glue which will allow you take your at and apply it to urban surfaces. Now creating wheat paste can be a pretty simple task but we want to teach you the right way—the scientific way! Creating wheat paste is basic chemistry so knowing what's going on the chemical process of the mixture will be helpful too you so you can create a perfect bond. But first lets start with a brief history.
Wheat paste has and can be use for a lot of things like book binding,decopage, wallpaper the list goes on. Back in the 19th century people used it for posting flyers, circus bills, propaganda, and posters of that nature. It wasn’t until the end of the 20th century that people could buy their own mixture instead of having to make their own. Since then people still continue to create their own wheat paste to hang up posters, prints, ads, propaganda, street art.
First we will kneed some basic house held materials like: Sugar, flour, a pot, a air tight container, a wisk, a bowl, a spoon, and a measuring cup...oh and water. You can find most of these things at your local grocery store and if you don't have water you should probably take care of some more important things first. Anyway, we will also need some materials to apply the surface too. Which will be: a cheap brush, a squeegee, a bucket and your art work.
Fill your measuring cup to 1cup, then poor it into the your pot and set it to boil. Water boils at 212º F, The water needs to boiling to act as a heat-mixture variable for both the water and sugar. This means the molecules within the water will gain a high enough liquid energy to help properly infuse both the water and sugar. Water turns into gas. just think about you wanting to move through a pack of people, its a lot easier when people are spread apart right?
While your water is boiling, grab your mixing boil and place 3 tablespoons of flower into into it then add 10 teaspoons of cool water to the flower; this is not the water that is currently boiling.Then stir the mixture with your wisk untill it is runny and will combined. It should look something like this,
Once your mixture is nice and runny and your water boiled add the flour mix to the boiling water and begin stirring the until the clumps of flower dissolve into the mixture. Its important to be constantly stirring so that the mixture will not settle and clump together. This is where the mixture of just these three items start to make the sticky paste; heres whats happening. Gluten is a natural protein which is found in the endosperm of wheat. This is what gives the wheat its strength and elasticity. Boiled with water these molecules are able to change the molecular structure. make sure your mixture is boiling like this.
Take your mix off the stove and add two table spoons of sugar, otherwise known as sucrose is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). When you add sugar to water, the sugar crystals dissolve and the sugar goes into solution. But you can’t dissolve an infinite amount of sugar into a fixed volume of water. When as much sugar has been dissolved into a solution as possible, the solution is said to be saturated.Mix for 30seconds then putt it back on the stove and mix again. By the end of this you should not only have nice wheat paste mixture by a strong arm too...Keep string the mix until it is thick! If the mixture is hard to mix through it might be too light. You can add extra sugar, glue or flower to fix this problem. Then let the mix cool.
Take your mixture and pour it into a container that is air tight. Not allowing air into is important because theres are natural substances (for the most part) and oxygen can deteriorate the mixture. (maybe add add a lib about oxygen science. . You now have your wheat paste.
