Default Curse the Shards!!!!

Hi there,

I'm having issues with shards breaking when I place them on the bead. It's an instant reaction, touch the bead with some shard and crack, little pieces go flying, followed by lots of cursing by me. Thankfully none have flown in my face! I know it's something that I'm doing wrong, it's not the product.

Maybe someone can tell me what I'm doing wrong? When I go to apply the shard I heat the bead where I want it to go first, and I also waive the shard a couple of times really quickly in the flame before placing it. Then, I touch the shard to the bead and either it sticks or cracks...then again with the cursing.

I'm working with silvered shards so maybe that has something to do with it? I wouldn't think so but you never know. Any thoughts would be greatly appreciated.

Carol

Try working further out in the flame when you bring the bead back into the heat. It's too hot, too fast bringing the bead into the flames if it's doing that.

I don't like to wave a shard in the flame, it's too hard to judge how much heat is in it. I hold the shard in the back of the flame, slowly bringing it closer as I heat the spot on the bead, you know you're too close it you get any movement. Once you've heated the spot and the shard has an even heat you can apply it and it shouldn't crack

Sounds like either the bead, or the shard, or both are too cool. When I add a shard to a bead the bead is warm enough for the shard to stick to it, and the shard has to be warm enough as well, either by waiving it in the back of the flame for a bit, or holding it near the back of the flame until it can warm up. Get just the tip slightly soft in the flame and touch it to a warm bead, Then use the outer edges of the flame to help you gently press the shard onto the bead. Use a marver to help push the softened shard onto the bead then a soft flame to finish.

Silvered shards are also very brittle. It takes a very light touch to place and let go with the tweezers.

If I couldn't improve my skills, I know I could improve my cussing!

you might try putting them in the kiln when you start it up before torching. I use my kiln a lot for heating up components, I bet it would help the shard shocking. you can use a heated rod to barely touch the corner and apply it off the rod.

Are you trying to put the whole shard on at once? I heat a spot on the bead, heat the very edge of the shard, attach that edge and then gently heat along the curve of the shard so it softens enough to push down onto the bead. Then you can blast it as much as you like.

I do it this way as well, and have never had a problem. Once that first edge is well attached I sort of roll along letting the flame heat the next prt of the shard as I marver it into place or let it just shape itself for a more organic style.

That said, sometimes a good stream of curse words is good for the soul!

Are you making your own shards? What glass are the shards?
