Summarize the following:
Before bringing your copper to the scrap yard, first sort your copper yourself into its three different grades.  Sort tubing and wire into their different categories.  This will give you an approximate idea of the overall value of your scrap copper.  Unsorted and uncategorized lots of copper tend to sell for lower prices. Before purchasing an expensive wire stripper, decide if you are going to be selling enough copper wire on a regular basis to make the investment worthwhile.  A general rule of thumb is that if you are stripping more than 1,000 pounds of wire per month, then you should purchase an electric wire stripper.  If you are stripping less than 1,000 pounds per month, you do not need to invest in a wire stripper. If you decide not to buy a wire stripper, warm the wire first.  Place it in the oven on low or put it inside a black box and leave it in the sun.  This makes the insulation softer and easier to remove with a handheld stripping tool. Never under any circumstances should you burn the insulation off the wire. Scrap yards will not purchase dust or turnings.  Many sellers don’t even bother saving these because they are not valuable.  If you have these materials, consider saving them until you have at least 10 pounds and then melting them down into nuggets with an electric or propane furnace made specifically for melting copper and other non-ferrous metals. A scrap yard may give you something for the nuggets, but be prepared to accept a price of up to 75 percent below market value for copper.  It might not be worth the cost of the electricity or propane to run the furnace.  If you do decide to melt down copper dust and trimmings to sell it, invest in the right materials for melting copper.  Copper melts at a temperature of 1,981 degrees Fahrenheit.  Purchase metal casting materials that are specifically designed to withstand this kind of heat and melt copper and other non-ferrous metals.  Typically, artists use these materials for casting bronze or copper sculpture.  You can find a furnace and other materials for melting copper at a bronze foundry.  Or, you can use an artist's tutorial, such as this one to build a furnace yourself.  Exercise caution.  Equip yourself with safety gear such as googles, face masks, oven gloves and running water.  If using a homemade furnace, carefully check all gas couplings for leaks.  Keep all flammable materials a safe distance away from the furnace. Be environmentally conscious when melting metals.  Use as much exhaust to heat the flame as possible so you are not wasting gas or electricity. Dispose of any waste from the process at a recycling center for hazardous materials. Some scrap yards will purchase transformers and motors that contain copper at a special “breakage” price.  But you should take them apart and separate the copper to get the best value.  When taking apart transformers, don’t bother trying to cut the steel because it is too hard.  Instead, cut the copper.  It is softer and more malleable.  Try heating transformers in a bucket over a fire for 20 to 30 minutes.  After heating, fill the bucket with ice water.  The transformers will become very weak from the sudden change in temperature and be much easier to take apart.  Exercise safety precautions.  Wear safety goggles to protect your eyes.  Wear heat resistant gloves to protect your hands.  Handle hot pieces with tongs to avoid having to touch them. Check commodity trading prices on NASDAQ or CNBC.com to find the latest price for high-grade copper.  Other trade service websites, such as specialty metal sites or investment sites, list the daily prices for metals including copper. Prices for commodities, including copper, are affected by market forces and change every day.  Between 2004 and 2009, copper surged in value from approximately $1 per pound to close to $4 per pound. The value dipped dramatically in 2009 during the recession to approximately $1.50 per pound.  But the price rebounded by 2012 to an all-time high of approximately $4.50 per pound.  Since then, the price of copper has decreased.  As of September, 2015, the price of copper per pound is about $2.43 per pound.

summary: Separate all metals before going to the yard. Strip insulation off copper wire to get the best price. Melt copper non solids into nuggets. Separate copper breakage. Research the best prices.


Summarize the following:
In a small dish, combine white toothpaste—do not use the gel toothpaste—with baking soda at a ratio of 1:1. Use a spoon to mix the products thoroughly. Spoon a portion of the mixture onto a clean rag. Use the rag to apply the baking soda-toothpaste mix to the stained area. Move the rag in small circles in an effort to remove the stain. Apply more baking soda-toothpaste mixture to the rag as needed. Continue to scrub the area until the stain has vanished. Be patient. It may take a while! Fill a small bucket with warm water and soap. Dip a clean rag into the soapy water and wring it out. Use the wet rag to remove the baking-soda toothpaste mixture from the floor.

summary: Make a paste out of 1 part toothpaste and 1 part baking soda. Apply the mixture to the stain with a clean rag. Scrub the stained area in small circular motions. Clean the area with a wet, soapy rag.

Instead of holding the yarn behind the left needle, bring it in front so it's close to you. If you forget and put the yarn behind, the stitch on your left needle will look like 2 stitches instead of 1. Don't worry about making mistakes as you work on this practice swatch. Pay attention to the mistakes you make, so you know how to prevent them in the future.
summary: Bring the working yarn to front.
