ADHESIVES FOR SILVER OR GLASS JEWELRY
Two weeks ago in this newsletter I recommended E6000 adhesive for glass jewelry. The next week John Morton of Redding, California complained that E6000 failed when exposed to moisture. Kiln Pointer back issues
Other readers have generously offered a wealth of ideas on adhesives:
Elaine Klugesherz of Saint Louis, Missouri wrote, “On the tube of E6000, directions suggest using this product when temperatures are 70 - 85 degrees Fahrenheit, allowing 24 - 72 hours of drying time for a maximum-strength bond, applying a thin coat to each surface to be bonded and WAITING 2-10 minutes before pressing non-porous surfaces together. The rest of the directions state that all surfaces need to be clean and roughened before bonding. I have used E-6000 for a long time and have not had a bond come apart.”
Yvonne George of Sanford, North Carolina wrote, “I have never been a fan of E6000. When living in Florida, the humidity was always a problem. Then I tried Liquid Nails. Okay, I know it’s for building houses. But I figured if it holds a house together, it will hold anything. I have used it to hang wires on the back of large decorative tiles, glass, and almost anything that needs glue. I have used it to hold posts on earrings. I am not allergic to it, but I would suggest a skin test if a person is sensitive at all.”
John Grosbeck of Clearwater, Florida wrote, "I, too, have had problems with E6000 not holding the bail to glass. I've found the Triolyse two-part adhesive to be a superior lasting product that doesn't show and holds up under all conditions.”
Lis-el Crowley in Windsor, Connecticut wrote, “Are you leaving E6000 for 24 hours without disturbing it? I use it extensively, even on rings, and it holds well. I rough up the silver and glass, clean with alcohol, apply the glue, and then let it sit undisturbed for 24 hours.”
Carrie Anderson in Kensington, Connecticut wrote, “I use Goop. It is clear, holds great, and is at the nearest Home Depot. I use it because it held together a pressurized filter for a pond pump that had been stepped on and broken in several pieces. Four years later, the pump filter is still holding up.”
Q. We do not have an enclosed room for a kiln. Our kiln sits on an outdoor porch under roof cover, and we also keep it covered with a barbeque grill cover when not in use. Are a kiln’s electronic controls going to be affected if the kiln is subject to the extreme variations in temperature and humidity that we have in North Texas?
A. I will use a comparison from the Isle of Hawaii, where I lived for two years. Everything there rusts--even refrigerators. Houses are made with galvanized nails because of the salt air and high humidity.
Cars in Hawaii rust quickly if parked in the open. They last longer when kept under a carport. And they last even longer in an enclosed garage. In the same way, a kiln on an open but roofed-in porch is subjected to more humidity than one in a fully enclosed garage. In humid areas, the kiln will last longer in a garage. Nevertheless, many people fire kilns on their porches.
Last week I described a thermocouple test. David Coggins, a kiln technician in Queensland, Australia wrote, "Your latest Kiln Pointer on testing a thermocouple with a paperclip is very good. This trick can be used to test thermocouples on most digital pyrometers as well.
"There is just one thing I would add: Before disconnecting thermocouple wires, always make a written note of the terminal each colour wire is connected to. Otherwise they might get reconnected in reverse, which would give confusing readouts. In your picture, the terminals are colour-coded to match the wire, but this may not always be the case.”
I have compiled a list of books on pottery, glass, metal clay, and other firing arts. As I have discovered, finding and using even one or two good ideas from a book can change your entire workflow. Click here for books
Let me know if you would like to review a book or suggest other titles. From time to time I update the list.
Have you ever noticed that people are happiest when they are busy? I’ve learned this by observing the Paragon factory. The busier the factory, the more cheerful the employees.
