Topics I've Started

Me No Understand!

27 August 2016 - 06:47 AM

I'm looking at different firing schedules for my kiln.

One I've looked at begins as follows:

1st ramp @ 50°F per hour to 220°F

I work in centigrade with my kiln so this converts to:-

1st ramp @ 10°C per hour to 104°C

If we start with an ambient temperature of 70°F it will take 3 hours to reach 220°F

 

Convert that to Centigrade:-

If we start with an ambient temperature of 20°C it will take 8 hours+ to reach 104°C

 

What am I missing?

 

:huh: :blink: :huh:


Spraying Mugs.

Glaze spraying mugs.

 

Is there a secret to not getting misses on the handles?

 

I don't make large enough quantities of glaze to dip pieces, so I spray pretty much everything.

 

I can (and do) go over the handles with a brush and touch up afterwards, but I'd much rather not.

 

 


Calcined Kaolin

05 July 2016 - 04:03 PM

I've been meaning to do this for a while but kept on forgetting:  today I remembered and made some calcined kaolin.

 

I don't need it at the moment but I do sometimes stumble across glaze recipes etc that require calcined kaolin.

 

Do I need to worry about any special storage requirements like keeping  it in an airtight container, or just chuck it in a box until I need it?
