Midwest Hearth Rock Wool for Gas Fireplace Embers, Made in USA, 6 Oz

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 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.
