The Glass Technique Identification Thread

[syrupy]

For those of us that are just learning about glass, and how it's made, and wondering what a particular technique is called. Please share a picture of a glass technique or feature and name it. Or post a picture of a technique and ask what it's called.

What is the technique called that produces these striations in the blues and reds?

That is acheived using striking colors or fuming the glass with gold or silver. Depending on a number of factors, the microscopic metal crystals will grow within the glass, creating patterns like above. Looks like amber purple, a classic striking color, in the photo.

Thank you that was very helpful. I assumed it was some hand-technique that produced the patterns.

With the patterns, is there a specific term for them or does it just fall under fuming or striking ?

Also, is this the same process when it has dot patterns?

The striations are just caused by variations in the glass, the amount of heat applied with the torch and within the kiln during cooling.
The honeycomb pattern above is created (usually) by dotting clear over a striking colour (amber purple again I believe). This causes the colour to strike differently when covered by the clear.

That sorta pattern is pretty much what I'd call honeycomb work.
Honeycomb doesn't necessarily have the stripes running through it normally, so that'd be a combo of whatever that technique gives the striped appearance and honeycomb.

(Not to be confused with a honeycomb perc... I can see why some peeps find glass terminology confusing )

Edit:

I'd love to know more about what goes into creating this overall effect if anyone knows

Typically a combination of silver (gives a blue tone) and gold (gives yellows and greens) fuming onto black tubing, the black provides a background to clearly see the fuming, you also commonly find marbles/pendants with fuming backed with black or a dark colour for the same reason.
I believe it is usually then sleeved in clear but not necessarily.

OK, need help with a marble. The pics aren't the best, but it's a marble that has a little piece inside that catches all kinds of light (almost looks holographic). What's the name for this kind of marble? The one I posted has a dark spot along the bottom, so when looking down on the marble, the background is dark, but from the side it's mostly clear.

Looks to be a synthetic opal encased in clear glass with some black backing. Gilson opals are compatible with boro so you can embed them in the glass while forming the piece.
A couple glassblowers doing very cool things with opals are Robo Glass and Big Z:

Also recommend checking Grandpa Glass's instagram, pretty much every glassblower buys their opals from Profound Glass:

I would guess an opal too.
I like how opal can have different color, depending on how light reflects off the rock.
There are two opals in this chillum

I have a combustion bowl in the space style, a lampworker friend of mine made. She said the blue is silver fuming and the stars are larger chunks of silver.

looks similar in appearance to alien tech. which is not a color... but rather a pull of several in layers. then when expanded it melts together to give the clouds of nebula and such... little fritt for the stars like some bigz dichro and other worked over layers.

baller tech
alien tech
serendipity
exc.
are all pulled colors.... I think im using the correct term...
