|  |  | |:---------:| | *Heat a small toaster oven to 300 degrees fahrenheit* | *It helps to heat up Silicone before on top of oven esp. 2 part molds* |
|  |  | |:---------:| | *Once the Alloy is hot enough, pour it using gloves* | *Tap the mold to remove bubbles. Notice strong surface tention* | The metal cools relatively quickly, and the casts are ready in under 30 minutes to be removed from the silicone mold. ### Individual Assignment > design a mold around the process you'll be using, produce it with a smooth surface finish that does not show the production process toolpath, and use it to cast parts #### Sculpting in clay I want to make knobs for my final project musical device. First I tried sculpting in a very soft clay that I found. It was a bit to soft to be stable so not as nice to work with. |  |  | |:---------:| | *The soft non-drying clay* | *a first attempt using the soft clay* | Then I tried sculpting in earth pottery clay. This required keeping things wet and was harder to work with, but it dries and keeps its shape. I had to make some tools out of popsicle sticks to add more details. |  |  | |:---------:| | *Homemade tools for sculpting the clay* | *A design for a potentiometer knob* | |  |  | |:---------:| | *The first mold for casting* | *The second mold for casting* | |  | |:---------:| | *A cast of a hand sculpted turtle/dinosaur* | |  |  | |:---------:| | *A cast of a ram* | *A cast of a bird* | ## Acknowledgments Thank you to Gert and Jen for helping with the casting process.
