So I have a portable ritual altar that is inside a briefcase. I accidentally messed up the altar surface a couple weeks ago. I just resurfaced it with a thin piece of sheet aluminum.
After I resurfaced it, I decided to consecrate it with the eclipse water I saved from the solar eclipse (I made a big bottle of it). I could feel the power in it after I was done, and the surface is pretty nice. It should be pretty potent for ritual work now.
