Warning: The following is not a technical explanation at all, it's just my limited understanding of something I'm discovering.
It's Twitter I'm talking about! Twitter, a free micro-blogging service that has been on the scene for at least a couple of years. The micro-blogging refers to the 140 characters you are allowed for your tweet (message) to others. You can use your 140 characters to send information about a great site you've found, business or just plain chatter. It doesn't matter which it just has to be short and sweet.
A brief and simple explanation of how Twitter works. First you need a user name, then you are good to set up shop. Twitter gives you a home page and this is where you tweet from. You follow and you have followers. There are sites galore that will help you find like type tweeters or those that just tweek your interest. What's nice is that you can be selective about the whole process.
I was relatively quiet the first few days but I've since made up for it. It's fun to see someone else's handcrafted creations and be able to tell them what you liked about it. Or you can just tweet back and forth about the creating process. That 's the social side but there is a networking component. When I tweet to someone I put my information out there such as my company name, a short bio and a link to my blog. It creates an opportunity for the blog to be read by others and if they like it perhaps they'll come back. Any of us trying toretail our jewellery would like more traffic either on Etsy, our website or our blog. I think this is a great way to potentially increase readership and get to know some interesting people.
This explanation of Twitter breaks all the twitter rules...I've said way too much! I hope that some of you non-tweeters are interested enough to check it out. You can look for me as Silver_bee and introduce yourself or let me know who you are!
This is a long post...grab a cup of tea, coffee or whatever and relax.
Okay so I've been wearing my earrings made from pieces of silver that I've
heated into a molten puddle and poured into a large pail of water and I can't
believe the response. I've been asked over and over about how to do it. This is
my best guess...maybe not the right word...my best...what the heck...my best
guess!
However, first a little lecture on safety. When you are doing any sort of
work with a torch wearing natural fibers and close toed shoes is strongly
recommended for what I hope are obvious reasons. Next make sure that your hair
is tied back, burnt hair is not a pretty smell or look. And while you are
outfitting yourself throw in a pair of safety glasses…to actually use. A well
ventilated area...oh like...the outdoors… is a must. A safe surface to set the
crucible while you are melting the silver. A cookie sheet from the dollar store
is not a safe surface! Unfortunately I learned that one the hard way. In the
photos you will see I was using a cookie sheet but I've since mended my ways. I
would suggest a fire brick or solderite pad. After all this...common
sense...which you have to have if you've gotten this far with a torch...I hope.
:-)
So you have your torch, it must be hotter than a butane micro torch. I use a
propane torch with the largest tip I have. It's often referred to as a Shark
torch because I use a disposable propane cylinder but the manufacturer calls it
a Whale Torch and you can get a connection for use with a refillable propane
tank. Consider your working space first before doing this.
You'll need a crucible with a handle. A little aside...I just found out that
the crucibles are made from clay bonded fused silica...well I had been
wondering! I use a 7 1/2 oz melting dish with a handle which looks like
this...only bigger. Mine doesn't have a pouring lip but I'm sure it
would be great if it did.
Next a large bucket of water...the taller the better. I fill it to the top with cold water.
Oh and I guess you'll be needing silver...preferably scrap. I never get upset when a project that I'm experimenting with goes awry because in my books it's just more for the scrap pile. I know not an especially thrifty viewpoint but I have to put a positive spin on my boo boos.
I also use Borax powder which is a component of most fluxes to sprinkle on the silver after it has melted.
One last little safety thing...please make sure that you have enough room to maneuver with the torch, brick, crucible and handle and large bucket of water.
Take a deep breath because we are about to start project "melt down".
Add a small amount of silver to the crucible. You can increase the amount in subsequent melting processes. The crucible will need to heat up before any melting can happen so be patient because the first time will take much longer that you think it should. Don't point the flame directly into the dish, as I found out, you'll starve it of oxygen and poof it's out.
By the way you can click on the thumbnail images and see a larger one...I just discovered this...yes I'm embarrassed.
Keep heating until the silver becomes a round rolling angry ball of bright silver, move the direct flame off the silver for a moment and add some borax powder. Focus the flame again on the silver and when it is molten use a carbon stirring rod or clean solder pick to stir it in. Technically I understand the use of the Borax but I just can't quite think my way entirely through this particular process but that's what I read to do...so I do it! So now you have that round rolling angry ball of silver again. Keep the flame concentrated on it while you
move the crucible over the bucket of water. You want to keep the silver molten when you pour. Keeping the flame concentrated on the silver, pour it into the bucket. Voila you have created your first water castings! Congratulations.
Now you can collect your little treasures from the bottom of the bucket. You'll be excited to get at them so remember not to put your arm with the watch into the water or forget how deep the bucket is and have your sleeves go into the water...with the watch. No...not a good idea.
Sort through the pieces and put the rejects back into the crucible...remember it's hot...and add some more silver and you are good to go again. Because the crucible is hot you'll find the melting process with the silver much faster this time.
You will notice that a there appears to be two liquids in the crucible and there are. One of course is the silver and the other is the copper that has separated from what was an alloy. When you pour I've noticed the copper won't interfere and stays behind and coats the crucible. I'm sure that there is a very technical explanation to explain all this but the one I'm going with is...copper comes to the surface of sterling silver when you heat it creating oxidation. I'm guessing that prolonged exposure to the heat brings the most of the copper to the surface.
A few others observations about water casting:
If you don't keep the torch concentrated on the silver when pouring you will end up with a big ugly, in my opinion, lump of silver.
If you hold the crucible very close to the surface of the water and pour quickly you are more likely to get the 'splats' and the 'water bubbles'. This is what I'm looking for...anything else goes back into the melting pot.
If you hold the crucible a bit above the water you will most likely see long needle like pieces of silver. Attractive and useful for some designs...but not mine.
The ambient temperature makes a difference as well...so a warm day brings different results than a cold day.
Some people have suggested using Ice cubes in the water...maybe I did not add enough but all it did for me was to make for very cold water when retrieving the silver.
All of these photos are in the photo album but I thought that it would be nice to have a visual as you were reading.
One last note...I can't guarantee the results and these instructions are derived from my own experience with water casting not a formal source. Have fun with it and bee safe! :-)
I'd love to hear your questions or hear about your experience with the process, so post a comment or email me...with photos would be great, but not necessary. I'll do collective post of the results!
This is the start of the process of doing either broom or water castings. Actually the beginning...for me at least...is doing the silver smithing, making boo-boo's, creating a scrap pile and then getting to the really fun stuff...playing with a torch! Maybe I shouldn't make the last comment public but if you've have done it or get the opportunity to do it there's an addictive or memorizing quality to it. Also you never have to be satisfied with the first, second or even third batch...just throw the rejects back into the crucible and the fun begins again.
This album is all about knotted pearls and hand crafted toggles. What a magical combination pearls, silver and silk make. The knotted silk creates a luxurious fluid movement. Of course I couldn't resist using some of my water castings...they keep showing up everywhere!
Welcome to my World!!
This is where it all starts. This very small area tucked into the corner of the kitchen is my "studio".
I love tools! They fascinate me because you do so little and they produce so many results.
I want to share with you my favourite tools currently in use, new tools just acquired to put into use and those on my wish list that I really think would be useful.
In time this is going to be a very BIG album!
