I created a couple of new wax model masters and I am ready to try doing two castings this time. I figure I should use the energy from the kiln to bake two flasks at the same time. You can see I made three models that I have sprued but I don't presently have enough silver to do all three casts at one time. I am sure they would all fit the kiln.
I have enough silver to do all three, but I need to recover the scrap sprue trees from the first two casts. I have 5 more ounces ordered. The first price break is at 5 ounces.
If you look at the previous attempt (my first home cast) you see I have changed how I mount these pieces. I am using a much steeper angle for the part and the bottom (top when casting) sprues are much shorter. I am attempting to make sure the melting wax drains properly and that the silver can get in via the shortest path. I hope I have learned my lesson.
My instructors were always enthused when a cast came out perfect as this process is as much an art as it is science. Following the rules is absolutely required but there is never a guarantee of a perfect cast.
I will add to this after the casting process.
This last section will be the last in these updates. I will of course be publishing a lot more casting activities. I'll start another article after I have cast the Texas Lone Star and the Triskele.
