Each panel in the wall is 64 x 64 inches. I start with a square cardboard tray that acts as a frame while I assemble the bottles with silicone caulk. I had some cardboard from a previous project and these proved to be handy. I built 2 trays so that a completed panel could be drying and another panel could be under construction. I place the bottles so that what I am seeing is the front of the sculpture, the side facing Main Street.
At first I had the tray on the floor and you can image after doing about 400 squats and bending over, my body was pretty racked after Panel 1 was complete. So I did what every good engineer would do and raised the tray to bench height. Wow, what a difference. With a design in mind, the next step is to gather the bottles you need. This is like harvesting in your garden for your meal. I take bottles from multiple bags so that I can get an even distribution, if that is the intent. Dorian is going to sort the bottles by color and size so that I can manage my “bottle palette”. I also keep an accurate count of the bottles when I select them. I tried to count the bottles after a design is complete and this is impossible.
For each bottle I check to see if any of the sides are dented or crushed. Minor dents can be pushed out with a chopstick (ancient Chinese secret). If the bottle is hopeless I remove the message and use a new bottle. If the bottle is moldy and gross, I set it aside. If the message is readable, I’ll use a new bottle.
If there is moisture in the bottle I’ll remove the cap and let it dry out. If there is no cap I put one on (I have a large collection of bottle caps, all sizes). Sometime the bottle needs to be “burped,” so I just open it to let some air in and close it back up.
After a bottle is deemed good to go I test place it in the design and visually note the contact points to adjacent bottles. It’s important to apply caulk to as many contact points as possible to get a good connection to adjacent bottles, especially in designs like “Confetti” where the bottles are more-or-less randomly placed. Also, caulk does not stick to bottle caps, this I found out on a test model. I guess it is the type of plastic or the fact that oils from the hands may be on it. I’m always playing a little mental game about seeing how accurate I am with the caulk placement. After a while you get pretty good at knowing where to place the caulk. You also try to go for just a little dab, not a big glob…that stuff is expensive! After the bottle is placed you repeat 400 times :).
Each design takes between 300-500 bottles. I want each design to be different so there is no set formula. My current rate of construction is 100 bottles an hour. That’s continuous work. I can usually go for an hour and then it’s break time, at least to get away from the fumes for a while. I have a fan for ventilation, but the smell of curing silicone is pretty bad. Silicone cures by combining with the moisture in the air and it releases acetic acid, the same stuff in vinegar. But I don’t want to get ill over this stuff so I try to get lots of fresh air.
I let a tray cure until I finish the next panel, which is always more than a day. Then I slide the mass of bottles out of the tray to an adjacent area where I mount the holding strips. By this time the whole mass acts as a single unit. I use a 4 ft piece of vinyl corner bead (the stuff they use for drywall corners) and caulk it to each side. This is used as a “tab” that allows me to screw the bottles into the wooden frame. After the holding strips have cured, I lay a wooden frame over the bottles and place clamps on two of the sides so I can raise the whole frame and bottles together. Then I screw the holding strip to the wooden frame and voila, it’s complete!
