Mark,
Sorry that I missed the Kugler colors booth at the Frankfurt fair. I am just now researching Kugler and this semi-old message popped up. Can you tell me if another exibit is planned in the near future? What is the COE of Kugler colors anyway? There sure seems to be a large assortment of colors. I´ve read somewhere that these colors are a bit tricky "striking". If I plan on fusing with them are there problems that I should know about before the "big purchase"? Where can I buy the colors in Germany? Their web site is a bit limited in that regard. I am so excited to find a large assortment of enamels manufactured in GERMANY! I´ll be able to save a fortune in shipping!

Mike in Italy did you have any success with the website? I just found it today myself. It sure does have lot of languages that it caters to...including Italian.

Kugler is COE96 and is compatible with the Spectrum System96 slumping glass.

It is color for glassblowing though, so many of the colors are "concentrated", and I have found that many of the reds will burn when slumping (which is a oxygen starved environment).

You have to be careful with some of the colors, in that they are not quite COE96... so for example K103 Silver Green in big chunks will introduce a stress point. When you blow it, you stretch and thin it, which reduces the stress.

You can get some nice reactions by putting the silver based colors on copper too... you get little "tree rings" around the color as it reacts to the copper.

no

I just bought some Iris Gold and Silver Blue reduction colors for lampworking and was told that it was 93-94 COE.

Kugler transparents are 91-95 COE, opaques are 83-86. I suspect that you will have trouble fusing with these unless you do quite a bit of testing.

Thanks! I read in http://www.glassaustralia.anu.edu.au/pa ... .pate.html website where the first one person listed used Kugler along with 24% lead Lennox crystal. It sounds beautiful! BE is great but the colors are limited. Are there any frits on the market that have a larger selection of colors but don´t have any risks when using them? If so who?

You might want to google Gaffer colors. made in MiddleEarth and very consistant. One Line is for blowing, one is for Casting. I think they maintain very high quality. I would be interested in other people's responses to their casting colors, especially mixing colors.

Well Jerry,
After researching everything that I could get my hands on I think that I will stick with BE. I´d already researched Gaffer but their website is limiting. It doesn´t specify which colors are opaque and which are transparent. The closest distributor would be England so I wouldn´t save on shipping. Some colors also have some different guidelines for fusing and seeing how I am a beginner I think that I will stick with what I already know. Thanks for the info.

Hi Kim,

for some unknown reason leaded crystal is more tolerant
with COE. It must be easy to obtein in Germany. If not, goto
Prag!

Pate de Verre is also a somewhat tolerant process, as the
glass can be mixed in so fine particles there is no stress
concentration. Kugler colors are strong. For casting
tints you may use perhaps 90 % clear and 10% color.

thanks for this info,,,,when you mix it 90/10, is it similar to most BE colored glass,,,,is there a problem with coe when mixing in higher concentratons,,,do you have any samples on your website,,thanks so much,,,rodney

Thanks again Lauri for your splendid information. You really know glass!

Kim

I have not really done pate de verre. The information was from my glass chemist, Mr. Antero Tammisto. He provides the Finnish factories with colored glass, around 96 COE.

I have used his powders to paint between float. No observable stress. Done the same with BE powder on float.

The more I ponder the Kugler colors the more confused I become....

So Brad what you are saying is that Kugler transparent doesn´t even work if it is mixed with Kugler opaque? Is glass blowing totally different? What am I missing?
