Here are some definitions of some of the terms used by glass workers that many people may not know the meaning of.
Gold and silver "fume" : Fuming pure metals is a technique where a small amount of the metal is placed directly in a hot torch flame, which causes the metal to vaporize into a smoke, or fume. When a piece of glass is held in the flame at the same time the "fume" will coat the glass.
There are a lot of ways to manipulate the coating for different effects, but in general, pure silver makes colors from an opaque white coating, to transparent blues and sometimes purple.
Pure gold when fumed, ranges from transparent orange to pink. Some of the coolest effects though are when you combine gold and silver in different amounts, then you can get golds, greens, oranges, pinks and blues together.
"Inside out" : This is a technique where, instead of just applying colors and fume to a tube of glass and melting it in(surface work), a tube of glass is heated until soft, and then flared blown open on the end and colors/fume placed inside the clear tube of glass. Then the tube melted closed on the end and the tube kept molten until everything applied to the inside of the tube is completely melted in. Nice 3d effects are created this way as the colors melt in and push up through the clear glass towards the surface.
"Murrine" : This is a technique where different colors of glass are layered line by line and eventually built up so when the end of the lines are looked at you can see an image. It is a lengthy process, with no real limit to the time and detail that can be put into it. My American flag, and ODB portrait murrines took the most time of any I have done, with the flag taking about 5-6 days, and the ODB more than a week. For the flag I created one star murrine then stretched it out, split it into 3 sections, melted those 3 together, then stretched it out again. That gave me a murrine with 3 stars which I then cut into 15 sections, I melted those 15 together in the right way to get the alternating rows of 4 and 5 stars, then I added a row of 5 single stars on the end to get the full 50. That was the longest part, after that I just had to layer the 13 red and white stripes onto the 50 star section, layer clear glass around the entire thing and then melt and stretch the entire thing down to a size that is usable on pipes and other work. I end up with a rod that I can chip a flag off of whenever I need one. I would recommend reading about murrine and millefiori on wiki if your interested in it. I think also that you can even see it done on youtube.
