My biggest hangup right now is interpreting what the data in these papers means and how I\u2019d put it in a visual form. I realize it\u2019s open for some interpretation, but I want to strive for SOME accuracy. I’m definitely going to use gluten as the medium because it has some interesting properties that make it worth utilizing to depict its structure.<\/p>\n

Experimenting with My Medium<\/h2>\n

\"Gluten<\/a><\/p>\n

What I\u2019ve found by playing around with gluten is that it\u2019s stickiest and most elastic when mixed with tap water. However, if too much water is added, the elasticity is lost and the mixture segments into smaller bits. Here it is mixed with excess water:<\/p>\n

Solutions, Baking vs Air-Drying<\/h3>\n

One of the first things I tried was mixing it with oil (left), vinegar (second from left), some water (second form right), more water (right). Then I baked it to see what would happen (bottom). After baking, the sample with oil got really crumbly, but the others stuck to the board without issue. The variations in water quantity were the most beneficial to play around with. I’ve decided a against baking because it sort of smooths out the surface, causes some bubbling, and I don’t really like that – I’d rather have the rough texture minus the bubbles.<\/p>\n

\nThis picture shows the gluten with different quantities of water after they have air dried, rather than baking.<\/p>\n

After reading this article about bread chemistry<\/a>, I decided to experiment with salt water. I started out making a super concentrated salt water and mixed it with the gluten and the consistency is more granular – it\u2019s not elastic at all. Even by diluting the salt water, the mixture just lacks elasticity when salt is involved.<\/p>\n

Planning the Piece<\/h3>\n

I’m also trying to think of contexts, and I’m stuck in a more artistic mindset so I’m envisioning a wheat field, or the inside of a person’s intestinal tract, but I could also do something more abstract looking. Without knowing much about the structure of gluten, I’m leaning more toward the abstract layout. I want to use the stretchiness and natural shapes that emerge from pulling\u00a0the gluten over the board. Maybe utilize the different textures of the gluten when mixed with excess water, little water, and\/or salt water. Here’s a sketch of what I’m thinking:<\/p>\n

\"gluten_project_sketch_IMG_0087\"<\/a><\/p>\n

I have an 8″ x 10″ cradled wood panel<\/a>\u00a0because the gluten adheres really well to wood and I think it’s going to be a nice surface to work on. I have tubes of watercolor paint that can be easily mixed with the water I add to the gluten, so I\u00a0should\u00a0have lots of flexibility with colors.<\/p>\n

Since the gluten I’ll be working with will be hydrated, I think using blues for the “holes” and a warm color, such as orange or sienna, for the web-like part will provide some context to the piece. Below is just a sample I did to see how well the paint mixes with the gluten.<\/p>\n

Once I get the gluten layered on the board I can come back in with paints and add in details to explain the amino acid sequences of some of it or mark out hydrogen bonds, etc.<\/p>\n

Feedback, suggestions, whatever! Let me know what you think.<\/p>\n
