This stuff works great. Given you refurbish the natural gas fireplace once every few years, I wasn't tuned into the details. Turns out, 6 ounces of this stuff would supply the whole neighborhood. Bottom line is it works great, but you must carefully tear off very small pieces of this "wool" and carefully place it around the area where flame shows during operation of your gas log fireplace. I tore off tiny pieces, spread them around, turned on the fireplace, took a look, turned it off and kept repeating this until I got the look I wanted. Very nice. But I maybe used 1/2 ounce out of the six ounce bag. So I gave it 4 stars instead of 5. This bag will last a life time. Maybe they wouldn't make any money on a two ounce bag but that's all you'll need. As for the effect of glowing embers, excellent. The product makes the look much better. As for lava rock, this wool is much more important. I bought and installed both. When you're 5-15 feet from your operating fireplace, you can't see details, only the glowing wool. Try this first. Then lava rock if necessary. The rock may disperse the gas better but this wool is the show.

Great value for the amount you receive. I had to replace the old and used-up Rock Wool in my fireplace. This product worked perfectly. Now my fireplace is cozy again.

Good product love it works.
