  • very nice blue glass "rocks"
Size: 10lb Color: Cobalt Blue
We're using a ten pound bag of the Calofulston fire pit glass rocks as a decoration in our front yard. We have an old anchor which is surrounded by bricks and shell mulch. We added the cobalt blue glass to brighten up the area and to match the anchor. These glass rocks have a mirror-like finish that reflects the sun nicely during the day which really brings attention to the area. For us, the blue simulates the water of the ocean beneath the anchor and is really beautiful and a striking contrast amongst the lush green yard. Although the intended use is for a propane fire pit, we find multiple uses for these sparkling pieces of glass. ... show more

  • I really Love the Flicker of the Calofulston Onyx Black Fire Glass
Size: 10lb Color: Onyx Black
I decided to give the Calofulston Onyx Black Fire Glass a go for a new look in the Living Room. Our large Fireplace had been converted to Propane years ago with the Lava Type Rocks & Rock Wool. Calofulston included enough Onyx Black Fire Glass for the Fire Log Sparkle effect, the Black Fire Glass Reflects the Heat & Light quite well adding warmth to our Livingroom. I couldn't be happier with a Product. I gave the Calofulston Onyx Black Fire Glass a Full Five Star Rating. ... show more

  • Looks great - adds color to my fire pit
Size: 10lb Color: Cobalt Blue
This fire glass is great. I have some around the outer edges of my fire pit. The glass gives a really neat look/sparkle when we have a fire going. My kids especially love it. All in all, this fire glass is a fun addition to any fire pit.

  • Great Option for filler
Size: 10lb Color: Onyx Black
I purchased this filler for the small fire pit we are planning. These glass bits are a nice sized and and while examining I did not find any sharp edges. Not that anyone should be running their hands through this, however with kids you never know what they are going to do. The light plays off them well, and I can’t wait to see how it looks with fire running through them. ... show more

  • Pretty Sparkles
Size: 10lb Color: Onyx Black
This fire glass is gorgeous. I previously had the glass pebbles that look like aquarium pebbles in my propane fire pit. These are such a major upgrade! They sparkle beautifully even when there is no flame, but they sparkle gloriously when there is a flame. I love them!

  • Are they all dusty?
Size: 10lb Color: Cobalt Blue
These are actually beautiful! Yeah, I said it.... I'm using them for plants instead! They look amazing. The price is a little high and the 10 pounds only goes so far. But they look worth the part.. They are really dusty initially just like regular rocks so make sure to open in a well-ventilated place and Rince well before use if needed. Recommended but pricey! ... show more

  • Pieces have sharp edges
Size: 10lb Color: Cobalt Blue
We have a fire table that needed some additional glass to fill it up. Couldn't find the same glass we originally purchased so we went for this 10 lb. bag of dark blue glass, and it was more than enough to complete the look. Our original glass was a smooth-edged blue/green color, and this stuff is a deep blue color that is mirrored on one side. The descriptions calls out a 1/2" size, but the actual size of the pieces varies. We like the varied sizes as opposed to all one size. One thing for sure is that all the pieces have very sharp edges. Not an item you would want to handle on a regular basis without gloves. ... show more
