#49422 Firing Schedule, Cone 6 Glazes

Posted by Bill T. on 05 January 2014 - 01:19 PM

Here is the MC6 suggested firing schedule (with a slow cooling if you want to use it).

 

                    Deg F/hour          Temp & hold

Ramp 1           100                       220/0

R         2          350                      2000/0

R         3          150                     2190/15       or where cone 6 is bent correctly, depends on your kiln

                                                                         mine bends at 2185

To continue with slow cooling cycle

R         4            -500                   1900/0

R         5            -125                    1400/0

 

 

"For bisque firings we recommend slow firing (100C, 180F per hour from 100C to 900C, 212F to 1650F).  This is when chemically combined water and organics are burn off.  This is especially important with iron bearing bodies to stop any reduction of iron which can over flux clay."  " For bisque firing a 5-10 minute soak at the end of the firing cycle can be advantageous......."   MC6 John Hesselberth & Ron Roy.    

 

My glaze firing with at Skutt 1027 pretty full is about 8 1/2 hours and bisque about 12 1/2.

I've been firing with Potter's Choice about a year mainly using Firebrick as the base for overlapping glaze. Like Teardrop now I have too many bottles on the shelf. I use a medium rise firing to cone 6 with a 10 minute hold. Have even used the MC6 slow cool schedule when I had a mix of glazes in the kiln. The secret, I have found, is to follow their directions carefully about application. Have to have enough glaze on the pot. One of the best combos I have is Floating Blue over Firebrick.
