I would just run the "slow" program for 2 or 3 hours then restart it using the "fast" setting.

(apologies if I'm over simplifying this  :) )


In Topic: Glaze Settling Out - What To Add?

Over on this side of the pond there is the regular bentonite plus a white firing one. The regular one can leave tiny specks in a transparent glaze. Don't know if specks are an issue with your transparent glaze. (macaloid and veegum don't leave specks, you use about 1/2 the amount of those as you would use of bentonite)

Axner joined with Laguna a few years back, I believe Rae's Smooth is an Axner made clay. 

 

From their website:

Characteristics
Cone: 5 
Wet Color: Gray 
Fire Color 
Oxidation: Gray/White 
Reduction: Gray 
Texture: Smooth 
Penetrometer Target: 7 
Avg. Shrinkage ±2%: 13% 
Avg. Water Absorption ±1%: 2% 
COE x 10-6: 6.85 

 

If you like Rae's then I would try some glaze tests on it plus check the water absorption. I would make up a bunch of test tiles and work on the glaze tests at the same time you are making pots. Nothing ever stays the same with clay, like John says test, test, test

Which Laguna clay did you find throws well for you? Laguna does provide some info for most of their clays which give a hint at how fussy glaze fit will be. Probably someone here who uses the same clay and could let you know how glazes fit on it. I would leave  the LL clay for now if you had problems throwing it, you can always come back to it later on when you have more throwing experience.
 
The other thing Laguna offers are sample boxes of 8 different clays in a 50lb box for 3 firing cones (10, 6 and 06). I don’t think most suppliers carry the sample boxes but they should be able to order it in for you. Saves spending a lot of money on buying 50lbs of clay you don’t like. Sample box (eastern clays) listed on page 26 of the pdf here: http://www.lagunacla...cc_prepclay.pdf
