Guide to Lampworking Glass

First, there is Satake Glass, also available from Arrow Springs (lead line only) in California, and Dogmaw Glass (soda lime, and 29 lead colors). Satake is a Japanese glass and comes in both soda lime (C.O.E. 113, 66 colors), and lead (C.O.E. 120, 94 colors). I’ve heard that the published C.O.E.s aren’t accurate and the lead line is more compatible with itself than the soda lime line. This is really soft glass, but has beautiful colors.

Then there are the C.O.E. 104 glasses. Effetre (formerly known as Moretti) and Vetrofond are both Italian glasses widely available in several glass stores. My favorite is Flame Tree Glass – possibly because it’s the only glass store I’ve actually been in, but more likely because it’s a really cool place, the studio is awesome, and shipping is FAST. But other stores such as Frantz Art Glass, Heritage Glass, Arrow Springs, Sundance Art Glass, Delphi Glass, and Moretti and More (just to name a few), also carry the Italian glasses.

Lauscha is a German glass that is also C.O.E. 104. This glass is known for its superior, non-scummy clear. Lauscha is available from (82 colors) in Connecticut, Glass Daddy (36 colors) in Texas, and Lauscha Lady (67 colors) in Canada.

Devardi Glass is a lead free C.O.E. 104 glass made in India by all adult labor. According to the website, “it has a lower heat requirement, it’s a stiffer glass, it has very saturated colors, the colors remain very true and the color of the rod remains the color in your work. There are also many colors in the Devardi line that do not exist on the market elsewhere. And many of the opaques change their appearance depending on the heat used or the oxygen/propane ratio.” It comes in about 94 colors.

Double Helix Glassworks is a US glass producer located in the Pacific Northwest. They specialize in striking and reactive glass that is C.O.E. 104 (about 10 colors). Double Helix is also offered at some of the stores listed above.

Precision 104, also called R4, made by Ron Bearer, is another US glass that specializes in silver, reactive glass. It is available from Frantz Art Glass (14 colors) and Rocio Studios. Precision glass is C.O.E. 104 and has 24 colors.

Yet another US glass producer of silver color is Striking Color. This glass is sometimes available from, and is produced in Georgia by Brad Schute in small batches.

More C.O.E. 104 silver, reactive glass by GT Glassworks (5 colors) can be found at Flame Kissed Glass.

The new Czech Republic company Preciosa Ornela (which is also the new name of Jablonex) is C.O.E. 104, and comes in 77 colors. This glass is available from C&R Loo Inc..

Another glass that hails from the Czech Republic is available from Check Glass. This glass also has two lines – soda lime (C.O.E. 104, 80 colors), and lead which is broken down into lead opaque (C.O.E. 103, 29 colors), transparent (C.O.E. 95/96, 34 colors), and shampoo (C.O.E. 95, 16 colors). This glass has some compatibility issues, so it needs to be tested before mixing colors – the website suggests sticking to the 15% rule. Also, encasing beads is tricky.

Creation is Messy, manufactured in China, is a relatively new US company based in Seattle. This glass comes in two lines. The C.O.E. 104 line is available from Frantz Art Glass (74 products), Moretti and More (89 products), and several others. The Messy 96 line is a limited supply of C.O.E. 96 glass, and is available from Frantz Art Glass (9 products), Moretti and More (6 products), and Phoenix Art Supplies (16 colors).

Phoenix Art Supplies also offers vintage C.O.E. 96 compatible glass dating from 1955-1989 (34 products). This glass was salvaged from German button and chandelier manufacturers.

Beadmaking 104® by Friedrich Farbglashütte GmbH, is another German glass. This glass (C.O.E. 104, 28 colors) is available from Hot Glass Color. Friedrich Farbglashütte GmbH also has a C.O.E. 96 line called KUGLER COLORS® with 74 colors available at Hot Glass Color as well.

Another German glass company that has both C.O.E. 104 and C.O.E. 96 is Reichenbach. The C.O.E. 104 is available in 34 colors at Olympic Color Rods, and Flame Kissed Glass. The C.O.E. 96 glass line is available in 211 colors from Olympic Color Rods.

Trautman Art Glass, a US based company, has two lines of glass as well. The C.0.E. 104 glass has 9 colors at Flame Kissed Glass, and the C.O.E. 33 glass has 24 colors at Generations Glass. A list of other distributors can be found here.

Gaffer Glass, produced in New Zealand with a warehouse in Washington, is 96 C.O.E. and comes in 89 solid cane colors with 37 veiled cane varieties and 15 limited edition colors.

GG Cane is also C.O.E. 96 and is made in Massachusetts by Gail Joseph. This is specialty cane and comes in 110 varieties plus odds.

Caliente glass, made in BC, Canada is available from Lauscha Canada and comes in 35 colors. The producer’s website is Caliente Glass.

System 96 by Spectrum and Uroboros Glass offers 35 colors in its C.O.E. 96 rod line. This glass can be found at Olympic Color Rods, Delphi, Sunshine Glassworks Ltd., and other stained glass suppliers.

Zimmermann Cane (C.O.E. 96, 20 colors) is available at Olympic Color Rods.

Bullseye, based in Portland, Oregon, has 108 colors in its C.O.E. 90 rod line. Heritage Glass and Delphi offer this glass for sale.

Borosilicate glass has a C.O.E. of 33 and is known as ‘hard’ glass. Northstar Glass, based in Oregon, has a lot of good information on their website about how to work their product, and is available in about 106 colors. Flame Tree Glass, Generations Glass, and several other glass shops (links can be found on the Northstar page) carry this line of glass.

Another hard glass company based in Oregon is Glass Alchemy. With a C.O.E. of 33, this glass comes in about 100 different colors, and is available from Generations Glass, Frantz Art Glass, and several other suppliers.

Momka’s Glass manufactures borosilicate glass (C.O.E. 33, 65 colors) in Washington State, and is available from Generations Glass, Hot Glass Color, and several other suppliers.

Origins Glass (Borostix) (C.O.E. 33, about 33 colors) is also available from Generations Glass, Winship Designs, and Sundance Art Glass.

Sundance Art Glass also carries Precision Glass Rod (C.O.E. 33, 27 colors). This glass can be found at Glass House Supply as well.

Next we have The New Color Company by Roger Parramore. This glass (C.O.E. 33, 17 colors) is available at Winship Designs, and a couple of other stores listed here.

Winship Designs also has 8 colors of C.O.E. 33 rod by the now defunct French company Colormax. Glasstronics color, or Amitronics color (C.O.E. 33, 4 colors) manufactured in India is also available from Winship Designs.

And finally, Wale Apparatus also sells something called Parasilicate Glass Rod (8 colors). I’m not quite sure what this is.

  1. Thanks for this list, it’s awesome and I can feel your pain when wanting to buy all the different types of glass. My husband wonders why I don’t use the glass I already have. 😦 I wish I had unlimited amounts of money and could buy whatever I want without anyone complaining about it.

  2. hi just found your great blog … my name is mona larson from Gaffer Glass USA … our warehouse is in Kent, Wa… we carry a full line of lampwork cane also… 96coe … more to drool over…

      Thanks for the wonderful list…wish I could try them all myself. I have one rod of Gaffer and have only made one bead with it…the color was wonderful and loved the sparkle…but do not know anymore about it…the rod was given to me as a gift..would love to work with it more and see if I liked it better than the 104 that I have been using for years…Barbara

  3. Thank you for your in depth list of glass suppliers & C.O.E. info. I’m curious about the differences in Reichenbach’s c.o.e. You said there are two different C.O.E.’s for Reichenbach; 96 & 104.
    I’ve been using Reichenbach for about 4 years & for the past several months I’ve had intermittent cracking after removing my beads from the mandrel, but only when I encase with clear. I kept thinking I got a bad batch & it was mixed in with left overs from a good batch. Is it possible that some of the rods from a separate order had a different c.o.e.?
    Love to hear your answer.
    Thanks. Lisa

    • Hi Lisa,
      Thank you for the comment! I suppose it is possible that the clear you have is a different C.O.E. I would think that all your clear encased beads would crack if that was the case though if it were mixed in together with the 96 only a few would crack. I don’t have a lot of experience mixing C.O.E.s together – yet. I have branched out from the 104, so I’m sure I will get something mixed up here sooner or later. I hope this helps, Robin

    i am from China and we are inneed of Opaque color glass rod wich can mix with Borosilicate material.
