schedules for 3 to 4 mm bullseye

[Lorac]

anyone any idea how to adapt a firing schedule for 3 to 4 mm bullseye??
I would like to make some lighter weight small candle holders using 3mm with additions  or 2mm x 2 layers with confetti inclusions...but have no idea how much to tweak the schedule in terms of temperature or time adjustments.
and IF they work ....how much to then tweak the slumping schedule....any thoughts or clever formula very welcome!
Cheers Fusers

Check out the Warm Glass uk website advice section, they have a great leaflet called 'heat and glass' which tells you all you need to know.

If you fire anything less than 6mm thick to full fuse, you will find the shape deforms. Straight lines pull inwards. You can get round this by grinding the edges to shape, then fire polishing as you slump.

But it's a lot of trouble to go to, to make candle holders 2mm thinner!
