All recommendations are welcome. In particular how to vibrate a two part mold without it breaking apart. I did not weigh the mix and water, but i suspect i used too much water. Also added about 2% plasticizer.

The grain size is small enough. and you appear to be pouring upside down (thumbs up). I think all along it was only the vibration. You may have a breakout. Hard to use last pour for a volumetric comparison if the mix ratio changed. Yeah, I hope it went well.

Weighing and adjusting for temp/ph is also key. These control the chemical reaction and thus the end result.
