It does create a beautiful color and realistic effect. It also is really easy to use because all you need to do is dump it into your fireplace and make sure it covers all of the open spaces. It also is really super light and makes me feel safe while my fireplace is on. The size of them do create what looks like a realistic ember, and we have had them in our fireplace all winter and they still look beautiful. That lets me know that they last a long time and they are Mega durable. If you need to replace these three or fireplace, I would purchase these for sure because they work great ## Features - REALISTIC GLOWING EMBER EFFECT – Rock wool mineral fiber glows like live coals wherever the flame makes contact, instantly transforming a gas fireplace or gas log set into a convincing wood-fire scene. Simply pinch small clumps and place near gas ports on the burner pan or on logs where flames touch. - MADE IN THE USA – Proudly manufactured in America using 100% asbestos-free mineral fiber. Unlike imported alternatives, Midwest Hearth Rock Wool is formulated to U.S. quality standards and has been trusted by homeowners and professional fireplace installers for over a decade. - COMPATIBLE WITH NATURAL GAS AND PROPANE APPLIANCES – Works with vented gas fireplaces and gas log sets. May also be used with unvented (vent-free) appliances; always follow your appliance manufacturer's instructions for vent-free applications, as requirements vary by unit. Compatible with both NG and LP systems. - INSTALLER-APPROVED TIPS FOR BEST RESULTS – For enhanced ember glow, use a stiff bristle brush to lightly flick a dusting of rock wool onto logs where flames will touch. Lightly spritz the log with water first to help the wool adhere. Do not pack wool tightly over gas ports β€” the flame must be able to breathe. - LASTS FOR YEARS – Mineral fiber composition resists extreme temperatures and does not deteriorate with repeated use. One 6 oz bag is sufficient to dress a full-size fireplace burner pan, with material left over for future touch-ups. Can be paired with lava rock or vermiculite for added depth and realism. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ZE2GSUK | | Best Sellers Rank | #101,270 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #5 in Gas Logs | | Brand | Midwest Hearth | | Brand Name | Midwest Hearth | | Customer Reviews | 4.6 out of 5 stars 4,905 Reviews | | Flavor | unflavored | | Item Form | Mineral Fiber | | Item Weight | 170.1 Grams | | Manufacturer | Midwest Hearth | | Manufacturer Part Number | MH Rock Wool | | Material | Rock Wool | | Material Type | Rock Wool | | Model Number | MH Rock Wool | | UPC | 638170653155 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Midwest Hearth - **Flavor:** unflavored - **Item Form:** Mineral Fiber - **Item Weight:** 170.1 Grams - **Material:** Rock Wool ## Images ![Rock Wool - Image 1](https://m.media-amazon.com/images/I/819ICGviWzL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: One of the product pictures shows the wool covering up the entire bottom of the fireplace - even over the flame holes it appears. Is that correct?** A: It looks like it actually sits in front of the gas line for the flames. But it does ignite and the colors are really pretty. One bag was more than enough. peace **Q: I replaced the fake logs in my gas fp with tumbled lava rock. if i use this under/around the rocks will it make the flames more yellow?** A: I don't think think so. After my gas fireplace has been started, the wool begins to glow, similar to burning embers. It does not change the color of the flame. **Q: Can this be used in an outside gas fire pit** A: Probably It holds up well in the indoor gas logs. It may rust outdoors though. **Q: how do I use with lava rock pebbles in fireplace basket?** A: I had lava rocks around my gas logs on the floor. I do not use them now but have the rock wool in the ember area. ## Customer Reviews ### ⭐⭐⭐⭐⭐ One bag will last years. *by B***E on June 8, 2023* I recently purchased the Midwest Hearth Rock Wool for Gas Log in the 6 oz. bag size, and I am extremely satisfied with my purchase, deserving a glowing five-star review.
