How is the silver glass made?

[houptdavid]

This Question was posted in the Bathroom (4-28-2010)

Is this a big secret or is it any place where I can learn about this?

Like double helix, tag, striking color, etc

- Do they just mix colors up and add silver chunks?
- How do they control the coe? just putting 104 coe for example?
- How do they stretch it?
- What do they do different to get a striking glass or a reduction glass?

There was a lot of good information coming out of this thread so I've taken the links that were posted and moved them here...

This is Brad's (Striking Color) website on hand made glass. http://handmade-glass.com/

This relates to COE 33 glass but I found very interesting. http://glassalchemy.com/index.php/the-formula?start=50

Look what I found on youtube!!

Here is an excellent article on what different chemicals do to glass

Might as well continue the topic here...

Silver glass is made like all the other glasses are made. Throw a bunch of stuff into the crucible, melt it together, and pull it into rods. Naturally its more involved than that, but with a small crucible kiln and a bag of 104 batch you could have a lot of fun. (Batch is a mix of all the ingredients you need to make glass, just add heat.)

Naturally, silver is one of the big components, however I don't know much beyond that. Cobalt oxide makes blue, gold makes pinks (gold and silver react together...). There are tables of what various compounds do to glass.

For the more practical lampworker you can start with effetre light brown, cobalt blue or gold pink and mix in silver foil a bit at a time. These three I know are reactive and produce very nice effects. When kronos first came out many people were convinced the same effect could be had with a mix of silver and cobalt blue.

If you wanted to take it further than that you could do some asking around and pick up the chemicals in power form. You can mix powders into the glass just as if they were enamels.


It can be fun to play since each "batch" you produce will be your own special odd-lot.

Do this with ventilation/respirators as needed.

Thank you so much for this incredibly detailed answer.. I never even thought about glass on this level and find the whole concept very intriguing and exciting!!! (and thank you, David, for asking the question <blowinyasakiss> ;))

Rach I didn't ask it I just moved it cause it was too interesting!

Oh (duh).. school's got me pretty tired and I missed that part.

Thanks for *moving* it, then! ;) (NOW you decide to cross your 'T's and dot your 'I's) :P

:love:
