How many rocks do you get? We have a propane round gas fireplace pit that is used for camping and we want to add more rocks to it. Are they good sized?

Nancy, I've got a gas grill that measures 20x36 and I purchased 2 bag of this lava rock, 14lbs., and it gave me a uniform 4 inch layer of rock across my grate. The rocks are between 2 to 3.5 inches in size and range in color between a rust red to a dark grey. They were exactly what I needed to provide an excellent grilling flavor after they were seasoned from a few grilling episodes. I would not hesitate to buy them again.

Can you use lava rock as a filler on the sides of a gas vented fireplace, where I will also be placing some ceramic pine cones?

I don't see why you can't use lava rock as a filler on your gas vented fireplace. The lava rock is used in our outdoor Propane Fire pit. It is durable. The Lava rocks have withstood rain snow fire(in the fire pit) and still look and work great. The only thing I would suggest is take them outside and hose them off first and let dry, they are dusty straight from the package. Does this help?

Can these be placed in the bottom of an electric grill to hold in the heat? Is it safe for those? Thanks.

I don't see why not. I put them in my gas grill and kept adding more as they disipated. I have went through quite a few pounds now that I have found a little place locally to buy them cheaper. Ace Hardware seems to carry them also but we don't have and Ace here.
