I am new to DIY projects and appreciate advice, but I have had conflicting advice on my fire pit project. My neighbors built a fire pit using landscape wall blocks. I have been over there several times and we used the fire pit and it was fine. I thought I could do the same at my house, so I went to Lowe's and bought Fulton retaining wall blocks (and 100 lbs of sand) and set up a small fire pit. At the store, the sign said the blocks were heat resistant, so I thought I was OK.
Now I hear that this may not be safe. I've looked ****** and some sites say using landscape blocks is a great idea, and others say that the blocks can explode and cause serious harm.
I am not sure what to do, and I know that TOH has the experts.
Thank you for your help :)
