New efficient GH for GlassyBaby

Thursday, July 31st, 2014

glassybaby, a local Seattle glass company, has commissioned a new energy efficient glory hole. Local equipment builder Jordan Kube has shared this video shows the prototype. glassybaby  will be receiving a custom size to suit their needs.

Just about all the materials have been ordered. There are a few local pick up items left.  A fuel/air mixer is on order. Construction can begin much sooner than that, hopefully next week. Jordan would like to have this equipment tested and in place by the end of August.

Woodfired Furnace by Ed van Dijk

Friday, January 3rd, 2014

From Ed van Dijk:     December 2013

Building and running my first woodfired glass-furnace was out of curiosity.
Knowing that thousands of years glassmakers had been making the most beautiful glass(art)work even without the use of electricity it was hard to understand how they were running a studio in the ‘old days’.
My first exempt was a firebrick “Roman”style furnace, build during a glass event some years ago in the small town of Lier in Belgium.
Build it in about two days time with a little knowledge of old designs and after a workshops in The Netherlands with guys building masonry heaters. Masonry heaters were as close as I could get to a combination of glass-furnace building and wood firing. romanfurnace1 romanfurnace2 romanfurnace4 romanfurnace5

After finishing building we started firing this first furnace to dry it. It took us about 30 hours of firing to get the temperature up till 1170 ºC. The 4 small pots of glass holding about 25 kg of glass were great to play with and open to anyone that wanted a try. We ran the furnace for about a week and did constant firing (24 hours a day) in shifts. Great fun that was, all those nights at the hot furnace, but lovely to get back to a normal rhythm of sleeping after the final party. Conclusion: ‘Its great to do but there is so much more to learn’ !

In the number of furnaces that followed I changed the interior design from “strictly’ Roman to Rocketstove based, till Rocketstove based with secondary air injection. The differences are enormous, but all of them run/ran totally without electricity.

Methane use at Landfill- Jackson County Green Energy Park

Friday, January 3rd, 2014

 The Jackson County Green Energy Park (JCGEP) utilizes clean, renewable energy resources to encourage economic development, provide environmental protection, and offer educational opportunities that together will help lead towards a more sustainable future for Western North Carolina. Located in Dillsboro, NC, JCGEP captures methane gas from the old town landfill, then uses the gas as fuel for a series of artisan studios, greenhouses and other ventures.    

Seattle visiting artists Robert Burch and Taylor Ames enjoying low-cost fuel usage from methane trapped in the landfill needing to be burned off anyway– might as well make glass with that fuel!!

Recuperation is worth investment

Sunday, October 20th, 2013

A recuperated glory hole side by side test was done in Seattle in June, 2013 by Jordan Kube and Hugh Jenkins using one of Hugh’s high temperature recuperators. Gas savings were found to be 30- 40% over the typical premix burner system, proving an excellent return on investment. Please stay tuned to BioGlass for the the full write up! See pictures below!

SUNY@ Alfred gets energy efficient glass & ceramics studios

Sunday, October 20th, 2013

The SUNY College of Ceramics at Alfred initiated this project to address safety and energy conservation issues in the glass blowing area of Binns Merrill Hall. Heat recovery and the safety of occupants were at the core of the project. As the design progressed, additional deficiencies needed to be addressed.

Given the immense heat produced by the furnaces, thermal comfort was a challenge. The most innovative application of this project was the use of displacement ventilation typically used in industrial settings. A combination of diffusers installed in two locations provide a “cool” work zone around the artist, which improves ventilation efficiencies by distributing a greater concentration of fresh air within the occupied zone.

 

Slide 1 Custom designed stainless steel exhaust canopies located above each furnace vent keep flue gasses from entering the room and capture the maximum amount of heat. Industrial ventilation techniques and calculations were utilized to design each canopy and provide proper air flow to match the furnace being exhausted. Each canopy is movable through the use of high temperature flexible exhaust hoses typically utilized in the transit industry. The 1,200° F exhaust temperatures made material selection a key component to the design, efficiency and useful life of the HVAC system.

The primary HVAC system is comprised of two large industrial style exhaust fans located on the roof, auxiliary exhaust fan, heat recovery coil section, and make-up air unit. The hot exhaust air from the furnaces is used to temper the incoming outside air through the use of the hot recovery section and a variable speed “run around” style hydronic heat recovery loop. The design of the heat recovery is so efficient that the system is completely self-sustaining with an outdoor temperature as low as 10° F.

Slide 1

Safety of the occupants was critical. Safety interlocks and alarms include automatic furnace shut down in the event of exhaust system failure; gas detection system to notify occupants of an unsafe work environment and automatic activation of HVAC system to purge the space; heat detectors at the ceiling to alarm the owner of high temperatures prior to sprinkler system activation; and custom designed control panel with indicator lights identifying occupants of HVAC equipment status.

Sound transmission was a major concern. Prior to the upgrades the instructor would shut off the ventilation system to teach the class due to excessive noise, which presented a safety hazard. The design included various noise reducing techniques and exceeded the client’s expectations, improving the environment and elevating the ability of the instructor to teach.

No conferences make for smaller gatherings….

Sunday, May 26th, 2013

2 glass conferences this year cancelled due to unforeseen circumstances and basically a lack of finances.   That is the crisis that many glass artists are facing and we at BioGlass are trying our darndest to help find some solutions that can bring relief to our expensive artmaking industry.

But alas,  with the conferences cancelled,  glass artists have decided to make smaller, more local gatherings.  The 50 Years of Glass celebrated last November in Oakland, CA was an enormous success that produced several presentations by local artists and an art exhibition featuring regional talent.   It was a great gathering of artists celebrating the 50 years of American Studio glassmaking and a strong showing of local support.

This year, GAS in Boston was cancelled and so was the GAAC in Calgary.   A small, local group of artists are still forging ahead with a regional gathering called Glass Boston.  http://www.societyofcrafts.org/learn/glassboston.asp

Although the GAS conference plans to regroup in Chicago 2014, with the return of the Green Panel, there are still some wonderful demonstrations and gatherings to attend in your local region.   We are a big family of glass artists needing to stick together and share information.  If you don’t find one close to you, host one yourself!

Coming up:    Green Glass Discussions & Presentations  May 31 at The Crucible in Oakland, CA and  June 8 at Pratt Fine Arts Center in Seattle, WA   Please email info@bioglass.org for more info.
