Small Volcanic Ash
If you are looking for subtle filler for your fireplace, look no further than Volcanic Ash. This quality material is an excellent choice for covering pans and serving as base for other materials, such as fire balls, that you may wish to lay over the top of the ash.
Volcanic ash will not burn; it withstands high temperatures due to its composition; this ash is the smaller pieces – 2mm or less in diameter – of volcanic rock. The size allows for a nearly smooth surface, much like sand or silica; however, volcanic ash will not clump during humid or moist conditions.
So how much volcanic ash do you need for your fire pit? Use these formulas to determine what your fireplace will require.
If your fire pit is rectangular: Width x Depth x Thickness ÷ 33.2 = Pounds of Volcanic Ash
If your fire pit is round: Diameter x Diameter x Thickness ÷ 42.3 = Pounds of Volcanic Ash
Don’t worry if you have a little bit of volcanic ash left over. Scatter some of the remaining ash around the fireplace edges to create a realistic look of ash that has fallen down from the flames.
Because volcanic ash, like other sizes of lava rock, does not burn, creating a faux look of ash may be the only way you’ll get a naturally messy look.
