Do not try this method of glassmaking at home. Wear a dust mask when handling silica sand. A charcoal fire fed with air from the bottom is hot enough to melt the combination of those materials into glass but not hot enough to make it truly liquid, so bubbles tend to remain and make the glass cloudy.
The cost of demolishing a home can vary significantly based upon multiple factors. An estimated range based on nationwide averages is $4,000 to $14,000. Some of the factors influencing the cost of a house demolition include location, size of the home, whether or not asbestos is present, and more.
A 1997 study for the U.S. Environmental Protection Agency (EPA) estimated the total cost of deconstruction for a 2,000-square foot residence at between $4.50 and $5.40 per square foot, compared to a cost of $3.50 to $5 for standard demolition.
