As I explained in an earlier post a group of students and I are trying to make mugs from aluminum oxide and zirconia. These are materials commonly used in lower cost body armors. Our goal is to produce a mug that can survive falls from great heights. However, while most body armors are hot pressed these mugs are going to be slip casted because you can't form a mug through pressing. This process involves creating a mold that will allow the mixed slurry to be poured. Once the mold has set it is placed in a oven and roasted.
Right now we are constructing sample molds to test the right amount of what materials to use. I hope to post a picture of our mold soon. I'll keep you posted.
