Hey everyone! I'm hoping to tap into your expertise. I recently discovered some strange material behind a thin layer of cracking plaster around my fireplace in the master bedroom. My house was built back in 1915 and has seen some questionable renovations since then. I'm really curious to know what this material might be and if anyone has tips on how to repair the cracks. I'd appreciate any advice or information. Thanks a bunch! [Check out the pics](https://imgur.com/gallery/8pA98JK)

Looks like you’ve got some old plaster or possibly lime plaster there. It's common in older homes, especially ones that have seen a lot of updates. To repair the cracks, you'll want to clean out any loose material first, then use a good plaster or filler that’s appropriate for historic homes. Make sure to match the texture as closely as you can! Also, if you’re unsure, consulting a professional who specializes in older structures might be a good idea.
Definitely some old plaster, but I'd check what's underneath if possible. It's crucial because sometimes there can be hidden issues like mold or water damage. For the cracks, patching them with a matching material is key. And if you can, try to keep the original character of the fireplace. It's part of the home’s history!
