This week, I investigated user experience by conducting further development of mold making. My forward leaning idea is to cast chocolate to form a hollow vessel, which would be an egg. The methods I tried were forming around actual raw eggs and hard boiled eggs. Many different tries were attempted, forming around the side, top, or halves (hard boiled for this try).
Along side my work with eggs, I spent the remainder of my time working with a plastic funnel and clay, I sealed the funnel with clay and mounted the funnel on a key-ed base so that it would form nicely and let me generate a two-part mold. To make the second funnel mold in PETG, I cutdown the first funnel and sanded the wide opening to reduce its height. This resulted in a scaled down funnel which I vacuumed formed around. The two resulting PETG molds make one two part mold that allow for the chocolate to be cast with an exact wall thickness due to the exterior and interior PETG surface.
