The fireplace below is a propane pan burner with a lava rock fill. You don't want to crush your own lava rock because of the time. You can use larger lava around the edges of the pan but you will want to use crushed lava in the pan up to the surface of the burners. The glass use in this fireplace was a Ford Blue Base Glass with Ford Blue Reflective Base Glass on top. Topped with Clear Pyrite Base Glass and Amber Topper accents. The install went very well except for the rock crushing episode.
The first pictures shows how it started and as you scroll down you can see the transformation. Very Nice!
This next fire pit was built by Tim and Sarah, they simply built this with stacker stones and a bit of ingenuity. The used a crushed lava base with Black Base Glass topped with Black Reflective Base Glass. Then they used a Light Amber Topping to create the Fleur De Lis. This was done with a propane valve that we supplied. They used a wood burning fire bowl for the pit. The tank was accessible from the back of the fire pit.
Add the base crushed lava. Note we do not use the 3/4" size? Way to large for the glass as it will fall through. You can use the larger lava and then over it with the crushed lava to save some cash!
Below if you notice the Pilot Light and Thermocouple just inside of the ring? This is a must if using propane, for safety.
