that elusive purple
Try overlaying 1116 (transparent turquiose) on the 1234 (striking purple) You get a wonderful blue-purple. Expensive? Yes - but worth it to get such a beautiful color.

Re: that elusive purple
i got a small piece of the thick shortly after it came out, yes it is a wonderfull purple, guess i need to check with my supplier to see how wonderfull their price tag is, i love purple but the one i have fires up almost black and i still would LOVE a magenta or fuschia ;P lani? how about fuschia or magenta? any chance of that coming out of the be factory in the next year or 2?judith wrote:Try overlaying 1116 (transparent turquiose) on the 1234 (striking purple) You get a wonderful blue-purple.

OK Ron, how do you do that? I'm puzzling over the reference and you come up with the link. Got to think you have too much time on your hands.Ron Coleman wrote:http://members.lycos.co.uk/Mollusks/kunst/haupt.htmlDon Burt wrote:The Murex Snail Protection League's going to flame you for that.Lynne Chappell wrote:clip:

5 seconds to become curious about some aspect of Murex snails
15 seconds to google Murex Snails
10 seconds to pick a reference from the hits
60 seconds to read it and answer whatever question he had
15 seconds to post a reply
Probably took me three minutes to post this reply. Actually, I don't have time for this, but I make time.

Don's got it Lynne. In fact you don't even have to type a thing, it's all copy, click and paste.Lynne Chappell wrote:OK Ron, how do you do that?

Copy the line of text db had in his post (Murex Snail), click on Google, paste in the google search box and click the search button and then start reading. Copy the url of a good link and paste it in the message box and post to the board. Bang Zoom.

Re: Pigment of my imagination?
One way a colour is made isBrock wrote:I don't really know much about this Ron, but i think the colour is in a colloidal suspension, and reheating alters it. Maybe! BrockRon Coleman wrote:I've been watching colors develop in Bullseye glass and I'm trying to understand the reason. I'm familiar with the process of "striking" for red and orange opal glass and see the results often.
Is it the same process when other colors seem to develop after firing a time or two?
Example, single rolled French Vanilla, a little puny on color before firing, develops into a saturated opal after firing.
Ron
The metal is in a coloid state
During reheating / reduction it disolves in2 the glass
This is known as a strikinig colour
U can have both states in the same peice of glass hence a different colour

Re: Pigment of my imagination?
I just got a sheet of BE's new striking violet (totally unrelated to shrinking violet). What an intense color..just beautiful...and so is the price tag. I ordered a sheet without asking $$$. Holy Moly!! - Barbara[/quote]Barbara Cashman wrote:i'm always curious why there isn't a good magenta or fuschia in the color lines of any of the fusible, and why the most intriguing ring mottles don't handle fusing well - no i've not tried them but i've been told they don't like going to full fuse but i would love to fuse a layer of ring mottles to a layer of irid or dichro....

Hi Barbara
If U wanna try these weird colours
Here is a few suggestions
Keep temp low
Soak or creap up in temp
Try flux as a low temp 'glue'
Or low melt enamel
This wil assist in reducing the surface tension therby giving lower melt fuze
Avoid hot direct radiation on the glass
If U wanna play with this stuff U gotta get sneaky n Cheet
If U realy wanna know about glass colouring U gotta hang out over craftweb

Re: Pigment of my imagination?
in discussions i had with kokomo, there's 2 ways to make ring mottles.Phil Hoppes wrote:Cynthia,
Ring Mottles are made by rolling the sheet glass on to a cold table as opposed to a hot table, which is the normal process. The combination of the cold table and uneven surface causes localized cooling on spots on the glass which causes the rings. This is also the reason they are not fuseable in the sense that the design dissapears when heated and then cooled evenly.
Phil
Some ring mottles are made with a chemical process and some are from the material in tabletop that the glass is being rolled on. Our catspaw mottles are made by the type of surface the glass is rolled on. The hot spots in the table shift the opal content giving lighter and darker density spots in the glass. This is not a cold table with hot spots. This is a hot table with localized ?hotter? spots. The chemical ring mottles made by other companies have a distinctive ring (often with a color shift) around each mottle where as our glass show light densities rings but does not affect the color.
he went on to state that other glass companies, like bullseye and uroboros, tend to use a chemical means to make the ring mottles.

so, would this mean that potentially ring mottle from be or uro COULD be fired - carefully maybe?

that's what he implied, but didn't state. i would suppose that the chemicals used would migrate or otherwise change in some manner at fusing temps though, so they still might go away. i suspect a very low slump temp of uro in a single layer might work. you might still get devit though, and low temps and antidevit sprays don't play well together.
i do know that when i tried kokomo ring mottles (a red/yellow combination) at fusing temps, i was left with a shelf of powder and slivers as it wasn't even compatible with itself.

Anti devit sprays will only affect the outside
If its cristalized within it will have no effect
4 those who wann play
Localised bafling / heating will have different effects on this glass
Just take care on way up n soak prior 2 aneal n aneal longer I U bafle

I'm sure I have heard Bullseye say that their ring mottles are a result of a temperature treatment, and therefore disappear on reheating.
