Does anyone like throwing B-Mix? I had some in the shop to try and I think is feels greasy. It is sticky. I like throwing porcelain better. But I wanted to make some more Crackle pots for the obvara firing so I tried it. It throws well but I don't like sticky. I think it comes from working in an all night pancake house and filling ten syrup dispensers each on 100 different tables. I have hated sticky ever since.It is the reason I didn't like printmaking. Ink is sticky.

What are your opinions on B-mix? These are thrown with 3 and 4 pounds of clay. 

 

I am jaded obviously, but I just don't like sticky.

Try Danish White from Laguna. Not sticky, porcelaineous.

TJR,

Thanks. I am looking a more local and less expensive sources. I think there is one source for that in Texas.

 

Jolieo,

Apply sodium silicate on the surface, dry it with a hair dryer of propane torch and then stretch it out with a rib using only the inside hand.

Marcia

I would rather throw porcelain than any white stoneware. White stoneware doesn't have any of the properties that make porcelain or stoneware wonderful.

I throw B-Mix 5 a lot. I guess you could describe it as sticky. I thought it was actually a bit slimy. A lot of scraping off fingers on the side of the water bowl. I don't love it, but I don't hate it either. I have a nice fit with all my glazes, etc. and I'm used to it. I like the color of it wet and after firing. How is that for a non-answer?

That is a good answer. I tried B-Mix 10. I don't know if there is much difference.

I had to scrape tools and hands a lot. But it did throw thin and easily.

 

Thanks for sharing your experience with it. I wanted to hear someone else's experience and opinion.

I'm thinking of trying B mix for one of my workshops ... anybody have any opinions on how forgiving it is when abused by being rushed?? or fired damp?

I use cone 10 B-Mix sometimes for handbuilt Shino glazed chawan.  But I add tons of two meshes of molochite grog, silica sand, and granite dust to it.... so I'm not really using B-Mix. ;)   Straight... yeah it is sticky and slimey.  Hate it.

Marcia,  I absolutely dislike B-mix, threw it for a workshop based on recommendations from the instructor.  Nothing against the instructor, it was the only clay on the list that was available in my area.  Pancake batter about describes it.  I will say it forced me to research and develop my own clay formula that I have been using for the past 3+ years.  I use if for everything from pits to cone 10.  I know it's not close to  you , but it handled through Dakota Potter's Supply in Sioux Falls, SD.  Aptly called Chad's Bod.

 

take care,

Chad

I find b-mix to dry very ineven and handles crack  because of this and its is always sticky-thats why I choose to throw 99.9% porcelain

B-mix does throw large and thats the only reason I see to use it. 

The lips dry fast the bottoms are sticky wet for days

I would rather throw other white bodies as far as stoneware

Try some 1/2 and 1/2 from laguna or Danish white as TRJ says-both are good.

I can't offer an opinion on B-mix, I don't think we have it in the UK, but I have to ask about your crackle pots Marcia: I know how to make them, it's a favourite method of mine, I generally use my normal clay (which is Scarva Earthstone - ES5,  if that means anything in the US) and I get cracking but nothing very heavy or deep.

 

I recently received  samples of some different clays and made a small pot with a heavily grogged clay which has cracked to a greater extent than usual, that's good, cos it's what I was expecting to happen. :)

 

Looking at the two pots in your pic in the first post I'm wondering if you have employed a different technique of some sort to achieve those long plain cracks between the closer cracked areas. Did you perhaps rib the pot out and then leave it for a while and rib it out some more, or was it all done at the same time.

 

I must throw some taller pots and crackle them, it shows it off so much better, if it warms up a bit I may do that this afternoon.

 

I don't like anything sticky either.

 

Here's an example of a finished pot (fairly small cracks)  and the recent more grogged one (still green)  with heavier cracking, but I wouldn't mind more.

Thank you, John, Chad, Mark, Natania, Chris  for confirming my reaction to B-mix. I haven't used much in commercial brands except for porcelain. I appreciate your input.

Ayjay,

I throw a tall cylinder and do the sodium silicate. Then I stretch it out with a rib. They are very thin by the time I am done. I have thrown holes in the walls by going too thin.

Marcia,

Like most of the lot here, I'm not a fan of M-Mix. I threw a couple hundred pounds of B-Mix 10 w/Grog for a wood firing last fall. I did find it unpleasantly sticky. I also found it to be intolerant of rushing the process and finicky with handle and spout attachments. I quite liked my final results using a Korean Celadon, but working with this body wasn't very fun until I unloaded bisque.

FYI, use of sodium silicate to obtain two scales of "cracks" http://tinyurl.com/yb52tvh Regards, Peter

It is no secret. Fairly common technique. Randy uses iron oxide for the contrast . I traded  a stoneware pot with Rob Hamlyn of Kelowna, BC that used this technique as well.  I fire obvara for my contrast.

Lots of questions on that link. 

 

Maybe that should be a topic in itself.

Marcia
