Hi everyone.  Im currently looking into building myself a rocket oven, and having little to no experience with building materials, this is a new realm to me.

I was looking into getting some insulation for building my rocket oven, and grabbed some high temp mineral wool for insulating the barrels, and for building the riser, (the stuff with the pink panther on the bag). But then i started looking around and saw people talking about stuff and i saw "rock wool", "ceramic wool", "mineral wool", "Super wool", etc.  And i was wondering if anyone could tell me what the differences are between all these materials if in fact there are any?

the most i have been able to distill is the fact that Super wool seems to be fairly different from the rest of them, and i am starting to wonder if i should have bought some of that instead.

Hi Jenkin;    
Rock wool is a brand name it is made with basalt rock.
Mineral wool is similar but can be made in several different ways.
Either would work as insulation around your oven but would not work in a riser.
Both require safety equipment to use.

Ceramic wool is high temp insulation.
It will work in a 5-minute riser but is very hazardous without safety precautions.
Tyvek suit, respirator, gloves, and goggles are all strongly suggested.

Morgan Super Wool is a high temp non-ceramic fiber blanket.
It is non-bio soluble in its unheated form.  Totally safe to work with. This cannot go in your lungs and stick there as a ceramic blanket does.
Short sleeves, no gloves it is a pleasure to work with.
Insulating your oven would be fast, safe and easy with it.
When Morgan is used in creating a five-minute riser, it is totally safe while constructing.
After burning, you would want to treat it as hazardous and use a respirator.  

The bottom line is the newest product suggested to use is Morgan super wool.
It is more costly than the others but ease and safety make it the product of choice.
Here are a few links for you to check out.

any idea if this mineralwool would work in applications of 600F or less?
Seems like its many tmess less costly than rockwool or superwool
