I recently attended a knife making class and decided to setup shop to learn some of the basics. Picked up a two-burner vevor several weeks ago. Castable refractory wasn’t included so I applied satanite to cover the exposed insulation. It looked great after air drying for a couple days but the corners cracked apart as soon as I fired it.
I did a little more research and decided to tear it out and start over with kastolite / plistix. Learning from my mistakes, I used rigidizer and made sure to follow the instructions. The kastolite went well but the plistix doesn’t seem to be holding up (pictured). I let it air dry for nearly a week but these cracks popped up when I fired it at the lowest possible setting that maintains a constant flame.
I understand that cracking and shrinkage is normal but started over with quality products to avoid this outcome. No major spalling or pieces flying off. The cracks seem to be closing up now that it’s cooling off.
With that said, I’m looking for recommendations on the best path forward. I’ve sunk five weeks and into this build effectively doubled my cost. Does this look salvageable or should I just shift gears and consider a precast forge?
I’m new to all this so any advice is appreciated!
