Torso Beads by Joy Munshower
One of our customers, Joy Munshower, posted some wonderful torso beads made with the Effetre glass rod colors ( Sunset, Alexandrite, Green Tea, Earth, Dark Ivory, and Neptune) and Vetrofond glass rod ( Topaz ODD ). They were such great examples of these colors I thought I would share them in this blog.
The murrini used were by Donna Millard
"Here's the fun side-by-side, before-and-after shots of a female torso sculpted out of "Neptune" glass. When I sculpt it it develops the "pewter" finish over its surface (and "haloed" around the Morning Glory murrini by Donna Millard interestingly)… I then etched the bead to expose the gorgeous mottled teal beneath." – Joy Munshower
I would like to see this bead in person because Effetre Alexandrite shifts hue slightly with different light.
This Green Tea bead looks like it was sculpted out of a Marble.

What is Zanfirico Cane?
I became aware of the existence of a type of Italian decorative cane called “Zanfirico” the first time I visited Murano back in the early 1990’s. It is stored in the same warehouse at Effetre with the murrini cane and was a titillating eye candy experience.
Zanfirico is a hand pulled cane style that requires a lot of skill to produce and is very popular with the traditional glass blowers on Murano, who do beautiful blown glass pieces with ribbons of fine twisting colors in stunning vases, bowls and other glass objects.
Frantz Art Glass has had Zanfirico cane available for many years, but it was marketed as “Marble Stock” in our catalog and on our website. The colors of Zanfirico that Frantz had in the past was not as delightful as the new batch that is now available and there is a better selection of cane sizes to pick from with this new shipment.
Since there are all these new styles and colors of Zanfirico, I decided to see what I could do using this cane style to make beads. I had a lot of fun seeing how I could make fancy 2 mm stringers out of 15 to 20 mm thick pieces that were 2 – 2 ½ inch long of zanfirico cane. I heat these short thick pieces of zanfirico cane in my annealing kiln at 1000F and then pick them up out of the kiln with a glass punty that is heated at the pick-up end to sticky hot. I then transfer the zanfirico chunk to the torch flame and start warming it and add a glass punty to the other end. When the zanfirico chunk starts to get soft, I start to introduce more twists into the cane and when it is ready to pull out, I continue to add more twists to make them compact enough to look good in a bead. This treatment takes a little practice, but is well worth it.
While I was experimenting with the zanfirico cane, I discovered that some of the cane patterns actually looked better when I applied a 5 to 6 mm cane directly to a thin bead cylinder on a mandrel and heated and twisted the cane down as I melted it around the bead. This technique allowed me to use the cane in its’ full size which made the cane pattern larger and more visible and I really liked the results. Instead of wispy twisted patterns of color, I got beefy twists that were more dramatic.
A photo of the punty and larger sized stringer that I pulled for an 8 mm cane, notice how it is wavy and this goes away when reheated.
If you like exotic stringers, I highly recommend trying some of this new shipment of zanfirico cane. It saves you from having to make it from scratch and it allows you to introduce details into your beads that are difficult to produce and very lovely to see.

These new colors are yummy, yummy, yummy and I had a blast melting them to find out how they work when I made them into beads.
I made beads with silver foil cores that were encased with the two transparent colors Azure and Appletini and they came out great. I discovered that if you apply the encasement gather when it is too hot, it will yellow your foil. All I had to do to correct this problem was to apply the encasement gather just a little cooler than white hot and it didn’t yellow the silver foil.
Rainforest and Atlantis are both opal colors and I have to say that Messy Color has the nicest and easiest opal colors I have ever used to lampwork beads. These two new opals are succulent and I couldn’t help myself and I mixed dichroic into three of the beads I made with these new opal colors with good results.
Check out the beads I made out of these new Messy Colors and decide for yourselves, but I give them a huge thumbs up!

What is a Cotisso?
What is a Cotisso? Having never heard the name Cotisso before, I had to do some research to find out what they were talking about at the Effetre factory. It seems that this is the name they use to refer to a chunk of glass that here in the U.S is called glass cullet.
So why am I talking about cotisso’s (A.K.A. cullet)? Because when Mike went over to Europe last October, he got the factory to let him pick out a bunch of different colors of these intriguing chunks of glass and Frantz Art Glass is now offering some of them up for sale.
I think cotisso’s are fabulous looking and look like surreal chunks of precious minerals. I got a big batch of cotisso’s a decade ago after pestering the factory manager endlessly to let me pick out some chunks to include in the glass shipment we were working on at that time while we were on Murano, Italy.
I love the cotisso’s that I have and I set them on my worktables, in windows in my studio and house. I also manicured several choice chunks by smoothing the sharp edges with a handheld dremel and I use them in my booth display when I sell my beads because the cotisso’s add such a delicious splash of glistening color to my bead display.
You may ask why I smooth the edges of the glass chunks I have in my bead display and it is because they are so beautiful, people want to touch them. To prevent anyone accidentally cutting themselves on a shape edge, I took a grinding tip mounted in a dremel tool and smoothed the less friendly edges off the glass chunks.
Another question I kept asking the manager at the Effetre factory is what do they keep them for? The answer turned out to be very interesting! When they measure out a new, from scratch batch of glass ingredients, it is all in powder form and is very slow to warm and melt into glass. They introduce a few chunks of cotisso’s of the color that is being melted and the solid mass of the cotisso heats up much faster than the powder and speeds up the entire melt.
When the factory is done pulling rods from a new batch of glass in one of their furnaces, they move the last of the glass batch to a shallow cast iron bowl while it is molten hot and they set it outside on their patio and let the glass air cool. The glass naturally fractures while it is cooling in the iron bowls and when it is completely cool, their turn the bowl over and dump the chunks of glass out onto the concrete patio.
Sometimes, the piles of cullet are very tall and they look especially beautiful when they are transparent and the sun shines through the glass sitting in the sun.
Don’t miss this chance to get a beautiful unique cotisso for yourself.
