I'd like to see just how often one forms, so I might try making some. If I get more than one, what kind of price are you offering? It sounds like small is more likely to work than large....

That's the thing...I can't find this thing anywhere on the net, so I have
absolutely no idea how much they generally cost. "Mike Beede" wrote in message ... In article , Keith Patrick wrote: Does anyone know where to buy a Prince Rupert's Drop online?

Once one gets the trick of making them, they are fairly easy to make.
One needs to build up a hot blob of glass that will drop free of the pipe or rod of glass and as it starts to fall into a container of water, pull/jerk the hand up to pull the tail clear of the falling blob so there is no long thin thread. Small ones - 1/8-1/4" - are easier in the torch, larger - up to 1"- easier from a pipe. If you don't do it right, you end up with spinnerettes of glass in the water, so you are picking the drops out of threads of glass after letting them cool down (especially the larger) in the water. Small ones should be broken wrapped in cloth, large ones double wrapped and tightly held - otherwise tiny fragments of glass are flying all over instead of making a small forceful whomp. When demostrating how strong the head is (hitting it with a hammer) hold the tail carefully and have some eye protection. -- Mike Firth Hot Glass Bits Furnace Working Website http://users.ticnet.com/mikefirth/I-UPSUMM.HTM shows recently changed files, click on link "Keith Patrick" wrote in message . ..

What is a Prince Rupert's Drop and what are they for?

They look like a tadpole of glass. Basically, the rapid cooling puts a
tremendous amount of pressure on the inside of the glass due to the surface cooling (and shrinking) more quickly than the interior. As a result of the stress, the bead is extremely strong and can withstand hard strikes with a hammer. However, if the tail is broken, the pressure is relieved, causing the drop to explode into a powder. "C Ryman" wrote in message ...

Probably not. The few returns I get on Russian tear drops that are not
references to songs are obviously decorative tear shapes which are carefully annealed. Like the icicles that have become popular the last few years. A Prince Rupert's Drop is a scientific curiosity created by violating all the normal rules of working with glass. Other than hitting it with a hammer to show strength and destroying it to show failure method, they are useless. -- Mike Firth Hot Glass Bits Furnace Working Website http://users.ticnet.com/mikefirth/I-UPSUMM.HTM shows recently changed files, click on link "Michele Blank" wrote in message ... is this the same thing a s a Russian tear drop? sounds similar in shape but i never tried hitting one with a hammer!

Here's a place: http://www.geocities.com/globalmagicshop/Effects.html
They're also called Prince Ruperts tears. Their creation is described in the old Hammesfahr & Stong "Creative glass blowing" book.

I can make them for you, along with " Baloney tubes" They are similar to PR
droppings, only they are a hollow tube. I would demonstrate them by driving a spike in a block of would using the Baloney tube as a hammer. I then drop a micro piece of silicon carbide down the tube to make it explode, and I mean EXPLODE. You do this while it is inside a Zip lock bag to contain the shards.
