In one sentence, describe what the following article is about: A piece of gold will usually be stamped with a mark indicating its type. A stamp of “GF” or “HGP” indicates that the piece is gold-plated, not pure gold. In contrast, a pure gold piece of jewelry may show a “24K” or other marking indicating fineness. Hallmarks are usually located inside the band of rings or near the clasp on necklaces.  However, be aware that some hallmarks can be faked. This is why it’s important to use a mark as only one of many indicators of authenticity. The hallmark may be very small. You might even need a magnifying glass in order to see it clearly. Turn on a bright light or lamp. Hold the piece close to the lamp’s light. Rotate it in your hand, so that you can examine all of the edges in particular. If you see that the gold appears faded or worn away at the edges, then it’s likely wear on the plating. This means that piece isn’t pure gold. If you hold the piece under a bright light, do you notice white or red spots anywhere on it? The spots may be very tiny and difficult to see. That is why it’s important to examine the piece under a bright light and maybe with a magnifying glass. These spots indicate that the gold plating may be wearing away showing the metal underneath. Hold a magnet directly above the piece. Lower the magnet until it is almost touches the surface of the item. If you feel as if the magnet is being drawn or pulled downward, then the item is not pure. The other metals in the item, such as nickel, are responding to the magnet. A pure gold piece will not draw the magnet, since non-ferrous.
Summary: Look for a hallmark. Look for fading around the edges of the piece. Look for spotting on the piece’s surface. Place a magnet against the potential gold item.

Put the mask over your mouth and nose. Secure the mask by placing the elastic bands around your ears. Make any adjustments necessary so that it is comfortable and you can breath. Once you have the mask secured, put on your safety gloves.  If the bands are designed to go over the back of your head, secure them behind your neck and the back of your head. If there is a nose piece on the mask, adjust the nose piece so that it is comfortable and you can still breath. You may also want to wear goggles or glasses to protect your eyes. Pour 100 grams of distilled water into your large glass bowl. Put the 68 grams of lye into the distilled water. You should avoid doing it the other way around; in other words, don’t put the water into the lye. You should do this procedure outside and far away from any children or pets.  Sodium hydroxide lye or “lye” is common ingredient in cleaning products. It is dangerous because it can burn your skin.  When you add lye to water, you create a reaction that causes a rapid temperature increase and fumes. You should not inhale the fumes created by this reaction.  Wear proper safety equipment when you add the lye to the water. Using a spoon or other implement, mix the lye into the water. You will notice the mixture getting cloudy. Leave the mixture in a secure location away from children and pets for twenty minutes. Once it has cooled down, it will look a bit more transparent. Stir the witch hazel into the mixture for two or three minutes until all of the ingredients are combined. Using your hand held blender, mix all of the ingredients together for a few minutes. You will know it is properly combined when the liquid takes on the texture of light mayonnaise. Once the mixture has the consistency of light mayonnaise, you can add one tablespoon of activated charcoal powder, a teaspoon of green tea extract, half a teaspoon of citric acid, five drops of vitamin E and twenty drops of rosemary essential oil. Blend all of the ingredients together with a hand held blender. When the mixture takes on the consistency of a normal mayonnaise, you can stop blending. Lay out your soap molds on a flat working surface. Using a ladle, transfer the soap mix into each of your soap molds. Cover the molds with a layer of plastic wrap. Finally, cover them with a clean kitchen towel. After twenty-four hours, you can take off the plastic wrap and the towel but you will have to leave the soap in the molds. One week after pouring the soap mixture into the molds, you can take them out of the molds. Place them on a drying rack and leave them to dry, exposed to the air, for one month. Although you may choose to air dry the soap for a shorter period of time (e.g., one week), it will dissolve easily and will not last as long.

Problem: Article: Get out a mini muffin pan and spray it with non-stick baking spray. Set it aside for later use. As you are doing this, preheat the oven to 400°F (204.5°C). A regular muffin pan is okay to use as well if you don’t have a mini muffin pan. Roll out the dough with a rolling pin. Cut the dough into 24 triangles. The triangles should be around the same size as if you were using a round glass or cookie cutter, but with three pointed edges. Put each triangle into a cup in the muffin pan. Leave two ends of the triangles sticking out of the pan so that you can remove them from the pan easier later on. Only a small portion of the ends need to stick out because the dough will expand as it cooks. First, put one tablespoon of tomato sauce into each cup of dough. Then, put pepperoni on top of each dough triangle. Add in the rest of the ingredients, like the olives and mushrooms. Finish by topping each dough with mozzarella sauce and parsley. Put the mini muffin pan in the oven and bake for fifteen minutes. The bites should be cooked through, and the dough should be browned when they are finished baking. Allow them to cool for a few minutes and serve warm. Cover the leftovers and keep them in the refrigerator for no longer than a few days.
Summary:
Spray the pan with non-stick cooking spray. Cut the pizza dough. Add the ingredients. Bake for 15 minutes.
