vermiculite or perlite
 
Hi I am trying to get started on building my brick oven but the only place that i have found vermiculite or perlite is home depot and they only have one type of each . is there a certain brand or a certain grain that I should be looking for and where can I get it Or can i use what they have at Home depot ?
I must also add that I have never laid a brick in my life but this looks like a fun project .

Try your local plant nurseries. Look for medium or course grade. I've read where some have found even better deals at concrete suppliers.

I would say that the greatest builds on this forum were constructed by builders such as yourself. They had no preconceived notions to how it should be done :D.

If you haven't; download the plans, do so, study several builds on the forum, and you will be OK :).

I found my zonolite at a masonry supply. 4 cubic feet per bag and reasonable too. :)

If you are using vermiculite or perlite to mix with cement to make what we call perlcrete or vermicrete then the easiest stuff to work with is the medium grade. The fine grade sticks together a bit better, but requires more water which then needs to be eliminated. The coarse stuff does not stick so well but is probably marginally better as an insulator. If using it dry and loose then the coarse stuff is probably better. I've found that a 50/50 mix of vermiculite and perlite works better when mixed with cement and water than either of them alone.

Look for horticultural grade perlite, it doesn't have the fines that block fill perlite has.
