How to Buy a Dart (I)
- Category: Tungsten Information
- Published on 02 February 2015
Here is a checklist of what you should pay attention to when you shop for a set of darts.
The supermarket is not proper places for buying darts. Some of these facilities sell darts (steel and soft) now and then, often combined with boards. In 99 percent of all cases this stuff is just plainly useless. If it's soft then the boards tend to have weird dimensions and poor quality (segments will break often with no replacement available). If it is steel then the boards are often paper boards which only last for a couple of darts. The darts supplied with these packages are the cheapest things possible, and in this case cheap doesn't mean low price, it means worthless.
The darts supplied with these packages are the cheapest things possible, and in this case cheap doesn't mean low price, it means worthless.Find a shop that has specialized in darts. If you can't find such a shop then look for a fisherman, hunting or weapon shop. Sometimes these facilities sell dart stuff (at least in Europe), and if they have a board where you can try their darts then you are in business. Pubs and bars where darts is played are also possible places to buy darts.
Take enough time to try different darts. You should spend at least 1 hour for trying different shapes/weights. If the shop doesn't give you this opportunity then it isn't a good shop.
When trying the darts don't judge by what you are hitting with them. Only judge by how the dart is feeling. This is important because when you are trying new darts it is very likely that you are more concentrated and careful than usual. This will result in better hits, but it's not because the dart is so good.
When trying different darts then first try a couple of darts and make the first preselection. For instance, try new sets of darts that look promising. Don't forget to try darts that look very odd for you, or shapes different from the ones you are used to! Prejudice is not the best thing when you are shopping for a new set of darts, you might find the perfect set where you wouldn't have expected it. One you have filtered out about 4 "candidates" you should go on further examining them, filtering half of them out. Then you have 2 sets left to decide which one to buy (most probably this will be the same dart in two adjacent weights).
If you can't get sure which set to buy then buy none of them, not both. If you find it unpleasant to tell the shopkeeper that you won't buy anything after he patiently assisted you in your 2-hour session at the shop then buy a couple of shafts or flights you'll need anyway sooner or later. In long term this will only kill your round-the-corner dart shop which will hurt you more when you discover that you are out of shafts the day before that deciding league match of the season.

What the Difference of the Ammoniu Metatungstate and Ammonium Paratungstate ?
- Category: Tungsten Information
- Published on 02 February 2015
The thermal decomposition of ammonium paratungstate tetrahydrate (APT·4H2O), (NH4)10[H2W12O42]·4H2O, in air to tungsten trioxide, WO3, was investigated under non-isothermal conditions using thermal analysis coupled on-line by a Skimmer® system to a quadrupole mass spectrometer (TA-MS) for evolved gas analysis (EGA), with X-ray powder diffraction (XRD), with Fourier
Some Techniques Used to Ammonium Metatungstate
- Category: Tungsten Information
- Published on 02 February 2015
Several techniques have been used to study the structure of the Keggin-type polyoxometalate salt ammonium metatungstate(AMT)—(NH4)6[H2W12O40]*nH2O, a potential fuel cell catalyst. The dehydrated salt is comprised of a mixture of crystallites of different unit cells in a centered eutactic cubic configuration, with an average unit cell of a≅12.295. Varied orientations of the Keggin ions in the cubic arrangement create the differences, and orientational variation within each unit cell size represents an energy well.
The History of Dartboard
- Category: Tungsten Information
- Published on 02 February 2015
The dartboard may have its origins in the cross-section of a tree. An old name for a dartboard is "butt"; the word comes from the French word , but the meaning is "target". In particular, the Yorkshire and Manchester Log End boards are differ from the standard board in that they have no treble, only double and bulls’ eye, the Manchester board being of a smaller diameter, with a playing area of only 25 cm across with double and bull areas measuring just 4mm. The London Fives board is another variation. This has only 12 equal segments numbered 20, 5, 15, 10, 20, 5, 15, 10, 20, 5, 15, 10 with the doubles and triples being a quarter of an inch wide.
There is a speculation that the game originated among soldiers throwing short arrows at the bottom of the cask or at the bottom of trunks of trees. As the wood dried, cracks would develop, creating "sections". Soon, regional standards emerged and many woodworkers supplemented bar tabs by fabricating dart boards for the local pubs.
The standard numbering plan with a 20 on top was created in 1896 by Lancashire carpenter Brian Gamlin. However, a great many other configurations have been used throughout the years and in different geographical locations. Gamlin's layout was devised to penalize inaccuracy. Although the most of the boards, the left-hand side (near the 14 section) is preferred by beginners, for its concentration of larger numbers. Mathematically, removing the rotational symmetry by placing the "20" at the top, there are 19!, or 121,645,100,408,832,000 possible dartboards. Many different layouts would penalize a player more than the current setup, however, the current setup actually does the job rather efficiently. There have been several mathematical papers published that consider the "optimal" dartboard.

How Much Tungsten in The Darts?
- Category: Tungsten Information
- Published on 30 January 2015
Tungsten darts come in many different varieties and percentages. You will see the most common being 70%, which usually means 70% tungsten, 30% nickel.
Sometimes mixed with copper for sets, however those are unusual to find . You can find darts with a trace of tungsten up to about 98% tungsten in the more expensive sets.
Remember that the more tungsten you buy, the darts will hold up better, last longer, and be thinner, which will help your shooting.

Which Tungsten Dart Weight Is Best?
- Category: Tungsten Information
- Published on 30 January 2015
Choosing weight of dart to use can be tricky and it is would be trial and error again and again. Basically a heavier Tungsten dart will suit a more relaxed throw, while a lighter dart would suit some one who wants to put more effort in. Ladies will choose a heavier dart to get more power, but this is not always for it.
Steel Tip Dart Weights
Range 18gm to 32gm.
Most common 23gm and 24gm - ideal for beginners
Soft Tip Dart Weights
Traditionally range 14gms to 20gms
Heavier weight now introduced up to 25gms
Most common 18gm - ideal for beginners.

What Kind of Material of the Dart
- Category: Tungsten Information
- Published on 30 January 2015
Someone ask the questions: "How high do I hang my dartboard?" or "What dart should I buy?" Considering I'm still get the question number one and I've had that information posted at this site for a very long time, I know this will not eliminate the second question altogether, but I should cut down on the amount of them. I was going to split this page up into two parts, soft & steel, until this little light went off and I realized the only difference between the two points and weights. So one page and it has been divided into the following.
Wooden Dart
You never see these around, but they are a lot of fun to throw with. They are made of lightweight wood shaft with turkey feather flights (no parts to replace). I have four sets and I ordered from Al's American Darts for using with their wooden dartboard. They weigh around 12 grams so they really aren't that much lighter than electronic darts. They work just fine with any bristle board.
Nickle - Electronic
Nickel-silver is yet another light dart that it is an alloy consisting of nickel, coppering and zincing. Like brass, it is easy for manufacturers to shape too.
Tungsten - Electronic
Tungsten, unlike brass and nickel-silver, it is a very heavy and dense metal.and t is usually mixed with nickel ,so you will see on a package something like 80-20 (80% tungsten/20% nickel). It is harder to work with but will last longer than the other two (especially the knurling). On average, a 20 gram tungsten dart will be ½ , the size of a 20 gram brass dart which will allow for tighter groupings on the board. This is the reason why most of the really good throwers use tungsten darts, but if you're just starting out, you won't be throwing tight groupings anyway, regardless of the dart you're using.

How to Chose a Suitable Dart
- Category: Tungsten Information
- Published on 30 January 2015
How to chose a suitable dart ?The best tungsten dart may can afford the good feeling when we play. If you have long fingers you may flavor a long dart. If you have small fingers you may favor shorter dart.
There are some tips for you:
Steel Tip Darts: It is a steel tip point that fitted to the barrel and thrown into a paper or bristle dartboard.
Soft Tip Darts: It is a flexible plastic tip which is thrown into a plastic or digital dartboard which has many small holes retaining the dart.
