I just tried for myself. I tared a measuring beaker, then tipped in 500ml of plain white flour. It weighed 374g, or 187g per cup. That's quite a bit more than the standard values, that range from 125 to 150g. When compacted by tapping it vigorously on the bench, the volume went down to 450ml (10% compaction). â
Prefab Fireplace: $1,500-9,000. If you are looking for a fireplace with a fairly substantial look, but aren't ready to pay a skilled mason to build one from scratch, then a prefab model is right for you. A majority of prefab fireplaces are made of reinforced concrete and equipped to burn natural gas or propane.
Most masonry fireplaces cost $5,000 or more due to the labor required to install each individual brick or stone within your home. A masonry heater (a very large stone stove) can cost upwards of $20,000 because of the tremendous amount of custom work that is required.nstallation for a natural gas fireplace can cost anywhere from $300 to $1,200 depending on the availability of natural gas and electricity in the location where you want the fireplace, as well as a number of other factors.
