Correct material for making a mini, indoors fire pit
Small fire pit inside trailer for winter season?
USA Today: 'Extremely dangerous': Feds urge against using tabletop fire pits (the kind we see in Vine all the time)

Hello everyone! Thank you for gathering here today
I wanted to build a small, indoor fire pit (about 4x4x4 inches) for my family and I for New Years. I have watched videos on making molds and making mini fire pits and I was planning on making them out of cement or instant concrete mix, however, after some internet browsing I read that concrete when subject to high heat can shatter or explode. I really don’t want to make something unsafe and would like to know what your opinions on the best material to make the fire pit out of? How would you go about it if you wanted to make one? Is there a difference in heat resistance between cement and concrete?
P.s. I also thought about having made a small tube (maybe the size of a toilet paper roll) out of metal, like stainless steel to put in the middle of the fire pit (where the fuel and flames would go) and maybe that would protect the cement/concrete from getting so hot it would explode?
I am sorry if this is not the correct sub, if so I will remove the post
Edit: I guess the “indoor” was a bit incorrect... I would primarily use this in a balcony
