June 2006 Issue #39 In This Issue ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~ * I’ve seen the light... Louise P. writes: “I have a question for you. I want to make those glazes with silver nitrate in them to reach those marvelous golden colors but I was wondering, I know that silver nitrate reacts to light so I will keep the glaze in a container that doesn't let the light through, but are there some other precautions I have to take while glazing? Should the pieces remain covered before getting them in the kiln? How long those glazes could keep?” Ah, Silver Nitrate can create a wonderful effect but can be such a pain to work with. For those of you who don’t know, Silver Nitrate is the stuff they put on picture film (remember cameras that actually use film before digital cameras ruled the world) that reacts to the light to produce a picture. So the stuff is very light sensitive. So how do you handle it? First you need to keep if from the light as much as possible. Keep it stored in a dark container or even a dark container in a dark container. Now you only want to mix up the amount of glaze you can use in a short period of time (a few minutes). Then after the pieces are glazes get them fired as soon as possible (a few hours or less). Again if the glazed pieces can be stored in a dark place the better off you will be. Another thing to keep in mind is Silver Nitrate is very reactive on your skin. If you get any on you it will be there for a long while so make sure you always use gloves when dealing with this chemical (you should be using glove to glaze anyway – right?) ~~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- Books, Music, Videos and that’s just the start.
