Casting an aluminum bronze calavera (sugar skull) for sale to the tourists. A calavera [plural: calaveras] is a representation of a human skull. The term is most often applied to edible or decorative skulls made (usually by hand) from either sugar (called Alfeñiques) or clay that are used in the Mexican celebration of the Day of the Dead (Spanish: Día de Muertos) and the Roman Catholic holiday All Souls' Day. Calavera can also refer to any artistic representations of skulls. This is a full video of the making of the mold. I've revised (and refined) my casting method since the previous video to speed up the process and render even better detail. I was getting too much shrinkage which was giving me a dimple on the back so I added a large feeder to the part. I'm using petrobond casting sand. The reddish sand is fresh petrobond that gets sifted over the pattern for good detail. The darker sand I use to pack the molding flask is refurbished petrobond that has been used several times. After casting, the really burnt sand gets put aside to be sifted, oiled (I use thread cutting oil), and mulled for reuse. I call the aluminum bronze alloy that I make "220"...which I mix by using 200 grams of copper and 20 grams of aluminum. That gives me a bronze that is 9% aluminum. I chose that mix because it is easy to use those numbers for different sized batches.

for all have sinned...
Romans 3:23 For all have sinned, and come short of the glory of God; 24 Being justified freely by his grace through the redemption that is in Christ Jesus: 25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
