The latest two torch sessions have yielded these beads. I've been working with Double Helix Kronos for a special order to replicate previous beads. The first time on the torch was last week after more than a week away. The second time was yesterday morning/afternoon.

As you can see, I sometimes make two beads per mandrel when using the same colors. After four years on the torch, I still have problems with kiss and dents on my beads when annealing at 940 degrees if they touch within the first hour of being placed in my kiln. I'm not sure why. I make sure the 'glow' is completely gone from the beads before placing them in the kiln. And 940 degrees is at the lower end of the annealing scale for soft glass. I don't have problems with my beads cracking or breaking after coming out of the kiln. But if they touch....ooooh, I just know they're going to be ruined and unwanted!
Since I was a child and read Cheaper By the Dozen, I've always been obsessed with efficiency and working smarter, not harder. Yes. I have always been a nerd. It even translates to how I decide to squeegee the water off my shower doors (vertically, rather than horizontally is faster for me. I'm not saying this is right for everyone). It's a sickness. I try not to impose it on others.
Anyway. Making more than one bead per mandrel helps me in several ways. I do not spend an extra minute heating up a mandrel for each mandrel. I do not spend an extra minute cooling down a mandrel before putting it in the kiln. It also allows me to eyeball more accurately the beads I make to get them more evenly sized. Sometimes. The beads are still handmade, people.
I'm not a production line. I'm not a Phillippino twelve year old in a factory without proper ventilation or eye protection churning out beads for ten hours a day, six/seven days a week. I have very limited time on the torch each week.....working full-time for the phone company and being a wife and mother of a five and seven year old does not leave much free time. So when I do get on the torch, I want the time to count.
Normally, I work for an hour making beads and filling up the kiln. Then I let it sit for 30-60 minutes before I fire up the torch again. At that point, I can move the mandrels around in my kiln so the beads may possibly come in contact with each other. They will certainly come in contact with the floor of the kiln (previously, they've been floating, held up in the air by the mandrels resting on a fiber blanket). But I can breathe easy that the beads will be safe from being marred by each other or any pressure from the floor. Which gives me a much higher success rate for every mandrel put into the kiln will come out without any problems.
