I'm looking to build one of Mud's cottage rocket.  I bought the Heat Riser ebook a while back as well.  https://amzn.to/3K37KBx is listed as Ceramic Fiber Insulation, is that the same as the Ceramic Wool listed in the riser ebook?

Hi Jerry, No, Similar but very different.
Ceramic fiber is hazardous to use without protection (like fiberglass)
Morgan Super Wool is a Non-Ceramic fiber blanket.
It is safe to handle until it is heated to over 1500°F (such as inside a riser); at that point, it becomes as hazardous as the other insulations.  
An N95 mask or a proper respirator, along with a long-sleeve shirt, is suggested.
