    It looks to me like overheated metal and too hot a mold. Those
    surfaces show investment breakdown. You need to have your flask down
    to 900-1000 F before casting and make sure your kiln is calibrated.
    Watch your metal temperature as well because those castings look
    like the metal was molten way too long and there is some serious
    metal/mold interaction. Casting is a multi variable process and there
    may be other issues that are effecting your results but, I would
    start looking at your temperatures.
