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.
Of course that's part of it. But, it needs to be done in a safe way to prevent injury and that takes knowledge of infrastructure and process. The average cost for residential demolition is $5 to $15 per square foot. For an average room that is 15X15 the cost will fall somewhere between $1,125 and $3,375. This is a rough estimate.
