I just read Rosemarie Hanus’ wonderful tutorial on how to make Silvered Ivory Stringer or SIS as it’s known for short. She gives a very clear description coupled with great photographs to help the process seem easy and foolproof. I am going to try her method as I hadn’t had much luck pulling SIS before and use another method that I found online (see bottom of this post).
If you are not a lampworker it might sound quite exotic. There is something captivating about the name and believe me, the results of using it can be very captivating also!
Here are a couple of my favourite beads using Silver Ivory Stringer -

SIS and Cobalt Blue

Cosmic Storm, Ivory, Triton and SIS
The first of these two has a very small amount of Silvered Ivory at the meeting of the cobalt and ivory glass. It’s creating an organic line between the two and causing reactions within the ivory.
The second bead has more SIS in it and really shows the wonderful reaction that can occur in the adjoining colours.
Ivory glass and silver do some beautiful things together!
Wanna close up of that reaction? Here’s a snippet of another bead -

Depending on how long you work the stringer (or even silver foil/leaf right on an ivory bead) the reaction can spread. This bead, using the same colours as the orange one above shows the reaction being spread as gravity has pulled the glass downward while I shaped the bead.

Sorry it's sideways!
I love the reactions in this bead – it makes me think of a butterfly wing.
Another thing that can happen with silver and silver ivory stringer is called fuming! This is when some of the silver burns off and ‘fumes’ adjacent parts of the ivory – or other colour that is used in the bead – causing a change in colour. It can be very beautiful.

You can see the results of fuming in the above bead, the silver ivory stringer has turned the ivory glass next to it a wonderful honey colour –mmmmmm……
If you melt glass and haven’t used Silver Ivory Stringer/ Silvered Ivory Stringer/SIS – you might want to try it!
As I said at the beginning of the post when I first tried to pull SIS I did not like the results I was getting so I searched online for instructions and found the method I use, it is not my invention and I wish I could remember where I found it. I make mine an entirely different way to Rosemarie, so there is no right wrong way to do it.
Silver Ivory Stringer for challenged stringer pullers!
Here’s how I create SIS.
You can use pre-made commercial ivory stringer or pull your own. I always use dark ivory. Like Rosemarie I prefer silver foil to silver leaf.
Using COLD stringer I take my silver foil, lick the ivory stringer (you KNOW you always really wanted to LICK your glass!!) and wrap the foil around the stringer once.
This gives me a length of stringer that is now covered with the foil, I repeat the process and work my way along the stringer covering it with foil. The little bit of licking helps the foil to stick to the stringer. Once I have a suitable length of stringer covered with the foil I quickly pass the stringer through the flame of my torch. This helps the foil to adhere to the stringer – be quick! You don’t want the stringer to melt, or the silver to burn off.
Voila! That’s all there is to it. I’ll try and find out where I came across this method and if I get a chance I’ll add a tut with pictures to my tutorials page too – stay tuned!
Thanks to Rosemarie and to whoever it was that posted the info that allowed me to make my lickable SIS – I am so proud to be part of a wonderful community who learns and shares from/with each other.
FOUND IT! The recipe I use came from Amber’s (Naos) thread on making dragon scale beads on Lampwork Etc. Thanks Amber and everyone else for all the tips in this thread – it’s a great read!
