I get the caution, but honestly, aren't reclaimed bricks usually pretty solid if they're older and have survived this long? Wondering if the popping issue is more about moisture trapped inside rather than age or type of brick... thoughts?
"Wondering if the popping issue is more about moisture trapped inside rather than age or type of brick..."
That's a good point—moisture definitely seems like a key factor. I've noticed reclaimed bricks can vary quite a bit depending on how they've been stored or treated over the years. Even solid, older bricks might have absorbed moisture if they were left exposed outdoors for extended periods. When heated rapidly, that trapped water expands and causes the popping you're describing.
But it makes me wonder... could sealing or drying reclaimed bricks thoroughly before using them in a fire pit help minimize this issue? Or is there something inherent in certain brick compositions that makes them more susceptible to moisture retention and popping? Curious if anyone has experience with prepping reclaimed materials specifically for high-heat applications like fire pits.
Yeah, moisture's definitely a culprit. I’ve seen bricks pop even after thorough drying—some old clay bricks just seem prone to it, maybe due to their porous structure or firing process. Honestly, if safety’s a concern, fire-rated bricks might be worth considering...just my two cents.

Fire-rated bricks are definitely solid, but they can get pricey pretty fast. If you're on a tighter budget, concrete landscaping blocks might be a decent alternative. I've used them for my pit going on three years now—no popping or cracking yet. Just make sure they're dry and avoid anything that's been sitting in damp conditions too long. Not saying fire-rated isn't better, just that there are cheaper options that still hold up pretty well.
Fire-rated bricks are definitely a solid choice, but honestly, regular landscaping blocks have worked fine for me too. Had mine about 4 years now, zero issues. Just build it right and keep an eye on moisture...common sense goes a long way with fire pits.
