The Future of Glass Colour : GAS Green Panel Murano 2018

2018 GAS Conference in Murano Italia GREEN PANEL by InMurano

For nearly 1000 years, glass has been created and developed on the small Venetian Island of Murano.   The traditions, the color recipes, the designs, and techniques have been passed on through the many generations of glassmakers.    

BioGlass got it’s start when Julie Conway, its founder spent time in Murano from 2003-2006 working with the glass Maestri at the Abate Zanetti glass school.    Between those years, the natural gas bill increased with a 60% delivery tax, and a double edged sword of the increase of Asian knock offs of glass,  some of which are even being sold on Murano to tourists!  

This has had a terribly negative effect on the glass economy and the protection of this rich heritage and culture of glass as we know it today. 

Modern day glassmakers are threatened on so many fronts:   cheap knock-offs is one of our major competitors, but also is the ever rising cost of fuel and the fewer and fewer spaces left open to host the expensive furnaces.  

The latest difficulty is now how to make the recipes of metal and compounds needed to create the luscious colors in glass safely and up to environmental standards.

The small island of Murano has had hundreds of glass making houses each melting their own color batch to their unique specifications.     Currently, color makers across the globe are having to invest in very expensive filtering systems to trap the contaminants and keep the process up to new environmental standards.

The GAS conference in Murano presented the very educated and astute panel Organized by InMurano

The crisis about to hit the glass community at large is the imminent ban of use of selenium and cadmium in color making.   These esteemed panelists were presenting solutions in order to protect and evolve this threat to glass as we know it.   Imagine no yellows or reds…. (!)  This will completely change the glassmakers palette! 

No answers were concluded yet, but solutions they will find!   These experts are exploring the deep history of Italian glassmaking back in the centuries before selenium and cadmium were used to make reds and yellows,  (no recipes have been written down to protect secrecy) to nano-technology of molecules to invent these colors in the future!!   


Spectrum Glass Announces it Closure for Summer 2016

 BELOW is the announcement from Spectrum Glass website :
Dear Spectrum Glass Customers;

We are making an extraordinarily difficult announcement today. After serving the art and specialty glass industry for 40 years, it is with very heavy hearts that we must announce the closure of Spectrum Glass Company. Due to several factors, it is no longer financially feasible for our company to continue to operate.
We will continue manufacturing through June and July 2016, and will sell the product inventory currently on hand over the months ahead.
Please know that our primary concern is to help ease this difficult transition for you and all the people we’ve been proud to work with and serve. We are exploring opportunities to transfer our product lines to other manufacturers to help minimize disruptions in sourcing.
We would like to express our deepest gratitude to all of our partners, customers, artists and others who have supported Spectrum Glass over these past four decades, and who continue to support us now. We will communicate updates here and via other channels as we wind down our operations.

You’ll find more information about why we made this decision here.

Using A Winch To Hot Pour Glass

"No more ladles for hot casting glass for me. I gave up all my student help when I retired from running the glass program at Alfred University. I needed to find a way to hot pour glass by myself. In the old days we would use 4 people running up to 15 ladles to fill my 7 foot rigid sand molds. Now I just push a button.

I designed and built this furnace to cast large pieces, often 7 feet long, with no help, no lap marks and perfect glass. This beauty uses a winch to tilt pour 5oo pounds of glass. The two 7 foot annealing ovens also run on winches. Push button glass casting finally. Turn off the sound when you watch the video. Thank you Julie Conway for asking for this post."
