Bullseye reactive and microwave kilns

[nigeljohnson73]

Are there any notes on the net on how to make the reactive glass react? I have a cryptic colour sheet from bullseye that says the reactive temperature is 810C but not a lot else. I think they will explain if you pay for one of their lessons but I'm not overly sure.

I have a microwave kiln and I guess I can't control the temperature but I have taken a couple of pieces up past what I normally would for a full fuse for a few minutes longer than normal with glass I know does react well and nothing seems to be happening.

Does it have to be hotter for longer?

It takes time for the reaction to happen. If you go up too fast, it's not likely to occur.

The same is true of glasses that strike to a new color.

Ah, ok, I thought it might have something to do with time. I might see if I can work out some wattage that keeps the heat high, but not too high.

Mind you with a proper kiln that ramp up and hold usually lasts a couple of hours though doesn't it?

Yes.

That solves that then... reactive glass filed for future use

Thanks guys.

Also note that you need to be firing with a glass that the reactive glass actually reacts with (for instance, copper bearing glasses).

Yep, I'm using the light turquoise frit with the reactive cloud. I've seen the output in a test sample so I know it does work. I've tried the Egyptian blue as well.
