Building a mold with sodium silicate

This is the way I use sodium silicate to build my molds for casting aluminum. Although I'm relatively new to casting I have had more success with this method than green sand and lost foam. Advice is always welcome, trolls are not, and if you think I need better PPE, you're welcome to send it to me. BTW- sorry about the fan noise in the background, I didn't realize the camera would pick it up so well.
