The New York City health department has identified 1700
coffee shops in the 5 Boroughs. I wonder how many of them have tables that need
a face lift? If each of these coffee
shops averaged 10 tables, that’s 17,000 table tops. And there are a lot more hotdog stands,
hamburger joints, casa de burrito taquerias, fast food establishments and restaurants
than there are coffee shops. I could see
a factory having more work than they could handle just making table tops.

Here are photos of cultured granite table tops made
for the new San Jose State University Student Union patio.

Making cultured marble, granite or onyx table tops is about
as easy as it gets and can generate some fast cash flow. There is little set-up/labor cost involved
and you can easily calculate exactly what your material cost will be after first
determining the area (sq ft or m2), then using our ‘Material Cost Calculator’ spreadsheet
you saw in our last post, to determine your total matrix cost.

To determine the area (square feet, square inches or m2) of a
circle, take π
(Pi) times the Radius squared. (A = π x r²)

If I want to find the area of a 36” diameter table top mold,
it will look like this:

(The Radius is
half the Diameter)

3.14 X 18 X 18 = 1017 square inches.

1017 square inches ÷ 144 = 7.06 square feet.

7 square feet X 8 pounds per square feet = 56.5 Pounds Total Matrix Mix
(Cultured Marble)

Matrix material cost varies depending mostly on the cost of
resin. Here in the USA, resin prices
vary between $1.50 to $1.75 per pound, giving us a total matrix cost between .59¢
to .66¢ per pound. Using an even .60¢
per pound matrix cost X 56.5 pounds tells us we’ll have $33.90 invested in raw
materials.
