In one sentence, describe what the following article is about: Each pen has a different type of ink, and ink is one of the most important elements of writing calligraphy well. Choosing a calligraphy pen is a highly personal decision, as the ink must be suitable for calligraphy, the pen must fit your hand well, and you must be comfortable writing with it. There are four types of pens that are considered ideal for calligraphy, including: Felt tip pens: These are good for beginners, as they are cheap, easy to use, and do not require you to prepare the ink before use. However, felt tip pens tend to run out of ink fast and the ink can soak through the paper or your writing surface. These pens are good for practice, but should not be used for important documents or works of art. Fountain pens: These are commonly used by intermediate and advanced calligraphers. These pens contain changeable nibs and ink cartridges. The ink feeds into a nib and is fed on to the page via the slit in the nib. Dip pens: These pens are used by advanced calligraphers, but they can be used by beginners with patience and practice. Dip pens consist of three components: the handle, nib-holder, or shaft, which is what the calligrapher grips when she writes, the nib, which is usually made of metal and has a slit which releases the ink, and the reservoir, which is the small cup or depression that feeds the slit. Some reservoirs sit on the top of the nib and some sit underneath the nib. The reservoir holds a small supply of ink for the nib so you can write several lines or letters before replenishing the ink. Brush pens: These pens consist of a thin brush, between 6mm to 20mm wide, with a head made of nylon or sable. The brush head should be made of short and stiff bristles to give you more control over the lines, as you will need to dip the brush into the ink to write. Writing calligraphy with a square brush is different than using a pen with a nib, as the brush will respond to pressure by producing a thicker line and the brush will make a scratchy or lined look when it starts to run out of ink. These pens are also messy to use for beginners and may be more challenging than using felt pen or a fountain pen. Choosing the right calligraphy pen may be a process of trial and error. Pick two different pens, for example, a felt pen and a fountain pen, to get a sense of how each pen writes. You may also want to narrow down your choices by thinking about how messy you want the writing process to be, and how simplified you would like your calligraphy set up to be. A brush pen, for example, will require preparing the ink and constant dipping in the ink as you write. But it may write smoother lines than a felt tip pen, which requires no preparation but may not write as smoothly. If you are deciding between a fountain pen and a dip pen, keep in mind dip pens give you more freedom to choose nibs, inks, and different holders or handles. However, they can be messier and more temperamental than a fountain pen. A fountain pen, or another cartridge filled pen, will be less messy and more convenient, as you do not need to prepare ink before you write. But you are limited to only certain kinds of inks and nibs when you use a fountain pen and fountain pens will be less flexible to write with than a dip pen or a brush pen. If you are using a dip pen, or a brush pen, you will need to purchase the ink for the pen. Use calligraphy ink, rather than fountain pen ink. Calligraphy ink is more viscous and will cling to the nib better, which will give you more control over the ink as you write. Look for thicker inks like India ink or Chinese stick ink. Avoid India inks that contain shellac, as this substance dries quickly and can damage the nib in your dip pen or brush pen. Many brush pens and dip pens will come in sets that contain the ink and the nib. Many fountain pens will come with ink cartridges and nibs recommended by the manufacturer. Start with the manufacturer's recommendations when you first start writing calligraphy. Some pens may also have converters so you can use different inks in the pen once you get comfortable with basic fountain pen ink. Fountain pen ink is thin so it will not clog the pen as you write, but the nib unit in more fountain pens is rigid, so it will not be as flexible as a dip pen or a brush pen. Other fountain pens may be piston pens. These come with an internal converter so you can dip the pen in the ink and basically have the pen suck the ink into the "cartridge". With piston pens, you do not need to invest in ink cartridges or a converter.
Summary: Understand the four most common types of calligraphy pens. Try one to two different pens at a time. Buy the ink for a dip pen or a brush pen. Get ink cartridges for a fountain pen.

The stronger the alcohol content the better this will work. Of course, your first move should be to use isopropyl alcohol, also known as rubbing alcohol, but there are other products that contain alcohol (or ethyl glycol) in them. If you see this listed as an ingredient on a product in your home, that product may be effective in removing nail polish: Perfume Hair-spray Hand sanitizer Spray-on deodorant Rubbing alcoholWhile alcoholic spirits shouldn't be your first option, clear, high-alcohol drinks like vodka, grappa, or gin will all battle nail polish.

So it makes sense that it could be used to strip away nail polish. For added effect, squeeze in half a lemon, or even some orange juice, to get powerful citrus cleaning power as well. Soak your fingers for 10-15 minutes before trying to remove. however, do not pick away the polish with your other nails as it can weaken them. This is not a solution for every day, as these chemicals can be dangerous. That said, they will work to remove nail polish, often just as fast as nail polish remover would. The following products should be a last resort, and should be applied in a well-ventilated area: Acetone Paint thinner Fluid Thinner

One-sentence summary -- Use alcohol and alcohol-based products to peel away polish. Use white vinegar, or a vinegar solution mixed with lemon juice, to fight nail polish. Use a powerful solvent or paint remover alternatively, though it is not recommended.

Problem: Article: Dogs can be great family pets as well as great tools for protecting your property from intruders. Some dog breeds are better for property protection than others. With the proper training, quality guard dogs will bark, bite, intimidate, and chase intruders away. In general, the best dog breeds for protection include: Bullmastiffs Doberman Pinschers Rottweilers German Shepherds Akitas Do not simply purchase the first dog you find. Dogs need to match the personality of their owners and you need to make sure you purchase a dog that you can take care of. For example, guard dogs are very active and need to be exercised often. In addition, they can be aggressive towards others if not properly trained; therefore, it is important you shop around until you find the right dog for you.

Research good guard animals. Shop around.
