What is fortified rosin?
Rosin is a weak organic acid. Fortified rosin is rosin to which additional acid groups have been added. This is most commonly done by a Diels-Alder reaction using either fumaric acid or maleic acid.
How do you apply violin rosin?
You basically rub the hairs of the bow onto the rosin. But, the rosin has to be scraped to gab onto the bow hairs. But good rosin does no need to be scraped before using. I one bought a violin that came with a free rosin and I rubbed it on for half an hour and nothing went on. I then bought a more expensive piece of rosin and it worked just fine.
How long does violin rosin last?
In my experience, rosin (for any instrument) has a shorter life than the manufacturers claim, because, long before the rosin goes bad, it gets dropped. Most of the rest of what is said about rosin is unsupportable. Since rosin makers rarely reveal all the additives and the purity of the colophon (the resin that is extracted from sap, which gives rosin its characteristic stickiness), it is a shot in the dark to make comparisons. In fact, for the manufactures of the high-volume lines, there isn't even a lot of guarantee that the rosin of this month is the same as next month's batch. Some manufacturers advertise that their rosin is made only of purified colophon, and some of it might just be. Others advertise additives which are supposed to make the rosin cause a "smoother sound", whatever that might mean. Some of these component are surprising, others are downright startling: Beeswax, for instance, melts at temperatures which are compatible with rosin-melting temperatures, and might just form a uniform admixture which is preserved through pouring, cooling, shipping, sitting on shelves, being rubbed on bow hairs, and then on strings. Others, like gold, silver and ground meteor bits (which are never qualified, let alone quantified) are supposed to have nearly magical effects on sound. It is said that La Scala's pit orchestra used the same block of rosin for decades, and that it only required a single stroke of a bow before a performance for the most perfect sound of Violin through string bass. The recipe for that rosin is, of course, lost to history. If you are finding that the effect of your rosin is changing within short periods (one or two months), it is a good idea to look to the amount of rosin you apply to your bow, how (or if) you clean your strings between sessions, and whether you are inadvertently contaminating the strings with oils from the skin of your fingers or other body-oils. Only after ensuring that you aren't causing the problem, should you worry about the rosin: are you using too much? Too little? Does your rosin produce a great deal of dust? Maybe one of the "professional" grades which are touted to produce little or no dust would work better for you. (These are sometimes sold as "non-allergenic", because some people become allergic to rosin dust and need a rosin which doesn't produce dust.) If you loosen your bow and run a _very_ clean comb which has not been used on human or animal hair through the hairs, you can see if you are using too much rosin or too soft rosin for your environment fairly easily: the hairs will not separate easily. If the comb becomes covered with rosin dust, you should be cutting back on application of rosin. If the hairs appear more yellowed in the area near where you hold your bow, you may be oiling them with finger oils.
In music what does pizz mean in music?
'Pizz' is short for 'pizzicato', an Italian musical term meaning to pluck a string of a string instrument (such as violin/viola/cello), as opposed to using a bow. It is a technique that most musicians dislike, as it gets rosin all over the fingers.
What is the purpose of a Rizla rolling machine?
The purpose of a Rizla rolling machine is to roll a cigarette using a Rizla rolling paper. Rolling a cigarette involves rolling a paper around a small amount of tobacco until it is ready to be lit and smoked.
What is the purpose of soldering?
Soldering is the process of using a bubble of hot metal to bond two electronic components or circuits together.

Soldering Station?
The key to getting a good soldering station is first knowing what purpose you are going to be using it for. After that, make sure the one you choose is sturdy enough, and has enough room for what you are doing. Avoid cheaply made stations as they are prone to defects.
What is a Hand soldering workstation?
A hand soldering Workstation is a station where you can solder metals together by yourself instead of using a machine

What problems can occur with soldering activities and how can these be overcome?
There are three classes of problems. First is the health hazards from soldering fumes. At one time, solder contained lead. Heat lead enough to melt it and it generates fumes that are dangerous. The rosin flux in solder also produces hazardous fumes. Proper ventilation will overcome this. The second is done through the use of corded handheld soldering tools, which have static electricity at their tips that can damage components. If you use corded soldering irons, get the kind with grounded tips. These ones have three-prong plugs. The third is thermal damage to parts. Using solders with low melting points, and proper technique, will solve this.
Why do pro basketball players use powder before games?
It's not actually powder that they're using but rosin. If you ever feel a new basketball (or football) it's extremely slippery. Rosin, (the same stuff used on the bows of string instruments) is a bit sticky and gives players extra grip. Popular players regularly seen using rosin are LeBron James, Kevin Garnett and Reggie miller. It's not actually powder that they're using but rosin.

What is soft soldering?
Soft soldering is using a heat to fuse metals together. In home improvements this is a useful skill to have when dealing with pipes and wiring.
When you are through using a soldering iron does cool it with water?
NO....it cools by itself.
What is the best soldering iron and tip to use on circuit boards?
Soldering irons come in a variety of sizes and shapes. There is a wide selection of soldering irons, soldering pencils, soldering stations and soldering guns available on market in the USA.Which soldering iron is the best soldering iron for you depends on the soldering work you are planning to do and how often you are planning on using your soldering iron. The following four factors should be taken into consideration when picking a soldering iron that will be used for soldering projects on circuit boards:1) ) type of the soldering tools2 wattage of the soldering iron3)temperature control4) tip size and shapeTypes of soldering toolsAll soldering tools can be divided in four different groups-Soldering pencils-Soldering station-Soldering rework /repair stations systems-Soldering gunsSoldering pencilsSoldering pencils are the simplest (and the cheapest) soldering tool. Soldering pencils are good only for simple do-it-yourself projects. The price range of the soldering pencils is $10-$30Soldering stationsSoldering station consists of two parts: soldering pencil and a power station. Soldering pencil is attached to a power station. Power station controls temperature of the iron tip in the wide range. It automatically keeps the iron tip at an appropriate temperature. Desired temperature of soldering iron is set with knob on the face plate of power station. Soldering station can be used for most of soldering projects. It can be used for soldering of through-hole components on circuit board as well as for soldering of very fine surface-mount components as small as 0603 and 0805. The price range of the soldering stations is $40-$150.Soldering rework /repair stations systemsSoldering rework/repair systems are complex soldering tools which are mostly used in industry or in the high-volume manufacturing facilities. This soldering systems are the most expensive soldering tools since they usually consist of power station and 4 or 5 hand pieces including soldering iron, hot-air gun, tweezers , vacuum pump which is used for the de-soldering work. The price range of the soldering systems is $250-$2500.Soldering gunsI do not recommend using soldering guns for fine soldering projects on circuit boards.The most popular brand names for soldering irons in the USA are Weller, Pace and Hakko. Aoyue soldering irons are less popular brand name in the United States then Weller or Pace. However, Aoyue soldering irons are much cheaper and they are good combination of quality and price.There is a wide selection of iron tips. Iron tips come in different shapes and sizes. For most soldering projects you can use screwdriver tip 0.062" or 0.032". For fine soldering projects and for soldering of small surface-mount components you can use conical tip 1/16".ConclusionI recommend a temperature controlled 50W soldering station. This soldering station will be excellent tool for most of soldering projects. My top recommendations are:-Weller WESD51 soldering station (digital)- Weller WES51 soldering station (analog)- Hakko FX-888 soldering station- Aoyue 2702A soldering station- Pace ST-25 soldering station
