In one sentence, describe what the following article is about: Since copper is quite soft, it should produce a muted, round sound. A test way back in 1867 described copper's sound as "dead," while brass emitted a "clear ringing note." This might be tough to judge without experience, but learning it could prove useful for an antiquing or scrap collection hobby. This works best for thick, solid metal objects. Brass objects made for industrial purposes often have a code stamped on them to identify the exact alloy. In both the North American and European systems, the codes for brass begin with a C and are followed by several numbers. Copper is often left unlabeled, but if you want to be sure, double check the code with this quick guide:  The UNS system in North America uses brass labels beginning with C2, C3, or C4, or fall between C83300 and C89999. Copper, if labeled, can use codes from C10100 to C15999, and C80000–C81399. The last two digits are often dropped. In the current European system, both copper and brass begin with C. Brass ends with the letter L, M, N, P, or R, while copper ends with A, B, C, or D.  Older brass may not conform to these systems. Some older European standards (which were used quite recently) list the element symbols followed by a percentage. Anything that contains "Cu" and "Zn" is considered brass. This test is usually not too helpful, since brass is only slightly harder than copper. Some types of treated copper are particularly soft, so you may be able to scratch them with a US penny (which is never true of brass). However, in many cases there is no convenient object that will scratch one object but not the other. Copper is easier to bend than brass as well, but it's difficult to draw exact conclusions from that test (especially without damaging the object).
Summary: Strike the metal and listen to the sound. Look for stamped codes. Check how hard the metal is.

In one sentence, describe what the following article is about: Place the chimney starter on the open grill. Most chimney starters will hold approximately one-hundred coals. How much charcoal you need will depend on how hot your want your grill. For high heat, fill the chimney. For medium heat, fill it halfway. For low heat, fill it one-quarter full. Your chimney starter has a spot on the bottom to add paper. Fill the space with one or two pieces of paper. Any kind of paper works. For example, if you have old newspapers lying around you can use them to start your chimney. You don’t need to add lighter fluid to the charcoal when you use a chimney starter. Use a long match or lighter to set the paper alight. Light it on several spots to ensure the fire spreads. As the paper burns, it will ignite the charcoal in your chimney. Watch the coals to make sure they begin to turn grey. If not, light another piece of paper under your chimney. When most of the coals are grey and you start to see flames on top of your chimney, pour the coals out into your grill. Spread the coals evenly across the bottom of the grill with a long-handled instrument, such as a pair of tongs.
Summary: Pack charcoal into a chimney starter. Add newspaper to the chimney starter. Light the paper. Pour out the coals.

In one sentence, describe what the following article is about: Eventually you will be able to stop doing the cleaning yourself and just run the business end, which is the only way you will be able to grow your business.  Start out with one part time employee. Train this person and let him or her take your place one day a week. Then have this employee take your place two days a week and so on. When training new employees, always, either train them yourself or have a lead person train them. There should be a lead person on each and every cleaning job––some employees have a tendency to slack off when they are on their own. Do a regular check the quality of the employee's work, to reassure yourself that your standards are being maintained. You will eventually get to the point where you have enough employees and lead people and you will be able to stop working in your business and start running your business. You will find that after awhile it will get to be too much trying to clean everyday and at the same time giving estimates, answering calls, scheduling, doing book work, obtaining new clients, etc. This is when it's time to consider a permanent base somewhere beyond your home (if you haven't already done so) and you might even consider franchising your business if you've been particularly successful in establishing your niche.
Summary:
As you start to get more clients, you will be able to hire more part time help. Change from doing the heavy work to managing the business.
