Review on 🔥 HANSWAY High Temp Carbon Fiber Welding Blanket - Protect Work Area from Sparks & Splatte (18 x 24 inches) by Kevin Zamora

I have used several of these blankets to wrap an aluminum casting for welding once it came out of the preheat oven. The ceilings gave off so much smoke that the fire alarm went off and luckily our system called us before the fire department was called. The cast was only heated to 750 degrees, well below the advertised 1800 degrees. In addition, wherever the casting pressed against the ceiling, it pressed it and left (jaws) the contour of the part. This compressed area conducts heat much faster than the surrounding ceiling, so keep that in mind. I've had better luck with a fiberglass ceiling from another seller. I've reused them for other projects so they don't go to waste.
