Q: Some glass makers use punty rods to hold a glass piece during the crafting process. When it’s removed, it leaves a mark called a pontil mark. Fenton uses snap rings, so most of their pieces will not have a pontil mark.  Pontil marks might look like a chip in the glass, a bumpy lump, or a dimple in the bottom of the glass.  Fenton has created some offhand glass pieces which do have a pontil mark. These include some very rare pieces from the 1920s and a few contemporary hand blown collections. Study the pictures in your books to familiarize yourself with Fenton’s style. By studying existing pictures, you’ll be able to identify characteristics which distinguish Fenton from other manufacturers.  For instance, if you find a carnival glass dish featuring a peacock, you can distinguish it from other manufacturer’s of the period by noting that in a Fenton piece, the peacock’s neck will be completely straight, while others curve slightly. The base will have a flat, collared surface, or it may have a ball or spatula feet. The edges are often smooth, bracketed, crimped, or ruffled, and are one of Fenton’s most recognizable characteristics.  Fenton primarily produced carnival glass, which has an iridescent sheen, although some of their pieces are opalescent glass, which is translucent. Fenton also specialized in a form of glass known as Hobnail, which is covered with small button-like bumps. Fenton glass is extremely high quality, and it should be free of air bubbles or other flaws. If your piece has obvious manufacturing flaws, it is unlikely to be Fenton glass. Due to similarities between manufacturers, it can be very difficult to tell the difference between some pieces. If you aren't able to tell after examining your piece, look online to find a Fenton dealer or an antique dealer in your area who specializes in Fenton glass.
A: Check the bottom of the glass for a pontil mark, which Fenton doesn't have. Purchase a collector’s book or find a Fenton glassware catalogue. Pay special attention to the bases and edges of Fenton’s glass. Look for bubbles or flaws in the glass, which Fenton shouldn't have. Contact a Fenton dealer or an antique expert if you still have questions.

Article: Cow manure has long been one of the most popular ways to fertilize plants. You can also buy boxes of bat guano, which contains nitrogen, phosphorus, and potassium, at many nursery and farm supply stores. Poultry waste is also a popular choice among farmers and gardeners. Sprinkle the substance around the roots of the plants you want to feed. Manure or animal waste in its fresh, raw form can be hazardous. Only use manure that has been aged, composted, or broken down into a safer and more usable fertilizer. These substances, made from the ground bones and blood of animals, contain high amounts of nutritious nitrogen and phosphorus. They are available from farm supply stores and nurseries in bags or boxes. Sprinkle meal around the roots of your plants.  You can fertilize plants as you're planting them by sprinkling bone or blood meal into the holes you dig during planting time. Try mixing bone or blood meal into your vegetable planting bed before planting seeds or seedlings, then adding more to the topsoil after everything is in the ground.  Most farmers and gardeners find that using an animal-based substance provides the best nutrition for plants, but if you're squeamish about using bone or blood meal, you could also try cottonseed meal. Working compost into your garden bed or potting soil goes a long way toward keeping the plants fed and healthy over time. It's still a good idea to fertilize them from time to time, but the nutrients contained in compost provide a good foundation for healthy plants.  You can make your own compost by collecting vegetable peelings and other food scraps in a compost bin. Compost bins need regular maintenance and upkeep over several seasons before they become productive.  Compost is also available for sale at nurseries.
Question: What is a summary of what this article is about?
Use manure, bat guano, or poultry waste. Use bone or blood meal. Nourish the soil with compost.

Problem: Article: Purchase a cleaning product made specifically for tires to remove dirt and grime. It is best to check the manufacturer instructions for your particular tires. Some will recommend using UV-rated protection spray, while others will recommend soap and water. Follow the outlined cleaning instructions, and purchase a proper tire cleaner. Most tire companies recommend using a spray tire cleaner. You can spray your cleaner directly onto your wheels, or apply it to your sponge and then rub it over the wheels. Clean the rubber wheels thoroughly, and use your sponge to scrub away dirt in a small, circular motion. You can also use a soft-bristled brush if you do not have a sponge. Make sure you use a gentle brush so you do not damage your tires. If your cleaner has a spray bottle, spray it directly to the metal of your rims. If you are using a gel cleaner, squirt a quarter-sized dollop onto your sponge, and apply it directly to your tires. Then, scrub the entire surface of your rims using a soft, foam sponge. Be sure to remove any grime built-up in the corners of your rims. Once your wheels and rims are clean, spray a wheel polish to the metal of your rims to make them shiny and beautiful. Spray the polish onto your rims, and rub it into the metal using a clean, dry towel. Spray the dressing onto a clean hand towel, and rub it into the sides and tops of your rubber wheels. Rub the dressing in a small, circular motion so it evenly spreads across the entirety of your wheel. Repeat this for all 4 of your wheels. The rubber will look slightly shiny after you apply it.  It is best to avoid using dressings with petroleum distillates or silicone, as they can sometimes damage your rubber over time. Purchase rubber dressing from most camping supply stores.
Summary: Check your tire manufacturer instructions so you use the right cleaner. Scrub your wheels using a wheel cleaner and foam sponge. Apply your cleaning solution and scrub the tires with a foam sponge. Apply a high-gloss polish to make your rims shine. Use a rubber dressing on your tires to protect them from UV rays.

Q: Begin by cleaning off the crumbs and other debris that may have accumulated on the oven glass. You can use a moistened cloth to loosen and pick up the crumbs. Or, you can use a vacuum attachment. Pour a half or full cup of baking soda into a bowl. Add in only enough water to create a paste that resembles the consistency of shaving cream. Spread the paste over the oven glass. Allow it to sit for 15 minutes. Use a dampened rag or microfiber cloth. Scrub the glass until it becomes clean. You may have to scrub firmly for tough grime and debris. Rinse the glass off with water. You can use a wet cloth to do this. Make sure all of the baking soda has been washed off. Use a dry cloth to dry the glass. If any tough spots are left, you can remove them with a razor. Gently scrape the spot with the razor. Make sure not to exert too much pressure, or you may scratch the glass. Once all of the remaining spots have been removed, wipe off or vacuum up the debris.
A:
Clean out the crumbs. Create a paste with baking soda and water. Scrub the glass. Rinse and dry off the baking soda mixture. Use a razor to remove grease stains.
