In Topic: Your Favorite Clay To Throw

Yesterday, 11:34 PM

Min, I don't use that much water.  I have not been in clay that long (7 yrs) but this is truly the first time I have had trouble with s cracks.  And because I like adventure, I switch up clays and use a speckled brown clay and sometimes a red clay.  Nary an S crack to be seen.  Like I said, I am trying to examine my throwing and compressing technique to see if there is something to be learned.  Thanks for the question though.

I have been keeping count of the number of pieces I have had to toss that was made out of Aardvark's  cone 6 Bee Mix.  I figure it's between 10-15%.   I am a good compressor, I do a slow dry, lightly covered in a cool basement with a stable temp, and during drying I will get at least 2 out of 20 bowls that cracks.  During a bisque I will get another 2.  And during the glaze fire another two.  Geez, that's more than 15%.   I like Bee mix, I like how it throws, my glazes fit very well on it.   But......I can't really afford that kind of loss.  However, I am wondering if it is how I am compressing.  I only get the cracks on really small and medium sized bowls.  Never on mugs and not on large bowls.  So I am really thinking about that when I throw.  So, to get back on track, I like Bee mix for how it throws....how my glazes fit....

But I also like Laguna SB red to throw with!  It's fun!   messy but fun!

I have had this happen a couple of times.  It looked a lot like your pics.  Both times were when bowls had sat on a shelf for a long time after washing, and I did not sponge it off again before glazing.  In my case, I think it was dust.   I know some people run water over their pots to clean them, but once I was taught the sponging method, I didn't have much trouble with crawling, etc.  I suppose it depends a lot on your climate.  not sure, but maybe you could try sponging??  Just take a bowl of water and a clean, damp sponge and wipe off your pots in and out.

Thanks Mark.  I will see about getting some.  It's not a common problem for me but a person needs something when it happens.  I had a small container of paperclay so I used that and the little bowl is being rebisqued right now.  I will let you all know if it worked.
