Comeback idea

A line of fire-rated refractory castable mixes and ceramic tiles for kiln builders and hobby foundries.

The write-up

FireShark carries a name that already sounds like heat-resistant engineering, and it's ready for a second act. Small workshops, pottery studios and home foundry builders keep looking for dependable refractory materials, and a fresh line of castable mixes and tiles fits that need well. It's up for a fresh start, and here's how you'd relaunch it: a starter range of castable mixes and tile kits for kiln and foundry builders, sold from getfireshark.com.
