#117478 Milling The St Cloud Granite

Posted by JBaymore on 29 November 2016 - 10:48 AM



If any of you have some successful recipes that you have used with granite, I'd love to know them.

 

Run a triaxial with your granite, any local clay, any local wood ash.  That likely will keep you in ideas for a long while.

 

One of my glazes is 33.33% granite, 33.33% local red clay from up the river from my house, and 33.33% mixed hardwood ash from my woodstove.  Another is 25% granite, 25% (milled) sand from the riverbank on my property, 25% mixed hardwood ash, and 25% of local clay.

 

This is the 1/3, 1/3, 1/3 glaze:  gallery_1543_134_4274355.jpg

 

With local materials... it is all about testing.

#117301 Milling The St Cloud Granite

Posted by JBaymore on 27 November 2016 - 01:23 PM

I get my granite from a local granite quarry a few miles from my house (NH ->"The Granite State").  From cutting, they produce a lot of what they call "dust".... which is anything from fines up to about 3/8" chunks.  For glazes I ball mill it for 6 hours (used to be in a home-made mill.... now a large double jar Shimpo ball mill). I use commercial porcelain balls.

 

Because they do architectural work with the granite... they have to have technical data on representative samples for the architects and engineers.......... so I can get analysis of the rock composition that is fairly close for glaze calc use.

 

It is a nice base for glazes.  I also use a local clay deposit.  And wood ash from my winter heating wood stove.

#117295 The Price Of Art

Posted by JBaymore on 27 November 2016 - 01:06 PM

First of all........ ANYTHING is worth whatever the market will pay for it. 

 

Is a Mercedes car "worth" what people pay for it?   Is a Big Mac "worth" what people pay for it?

 

Only the purchaser can decide on that fact.  If you can't afford a Mercedes or a Big Mac......... then you can't even consider whether it is "worth" the money.  That colors your approach to the object.  For some folks... a Big Mac is unattainable.  For some folks the Mercedes is unattainable.  For some folks the Klein is unattainable.

 

If you have real MONEY (as in capital  M ... O....N....E....Y).....history has proven that artwork is one of the absolute BEST investments you can make.  Beats stocks and bonds.  So many affluent folks buy art not for the appreciation of the piece itself (although that might be a side issue)... but for the potential appreciation in value. 

 

Artwork from a specific artist is something that is not at ALL "replaceable".  An artist makes a fixed number of works in his or her style in a lifetime.  When he or she is gone... any new work is also gone.  IF that artist is considered important (separate subject) ...... as they get older their work tends to appreciate (as well as get better, one hopes).  When they die.... it seriously appreciates.

 

The important part of that investment potential is to "buy right".  So there needs to be a consensus that the particular artist is "important".  The art world has to have recognized the artist AS important in some manner for some reason.  Then investors will see the pieces AS investments.  And people like Christies make a killing on the commissions.

 

Places like Christies cater to investment types.  To investors........ apparently Klein is considered a decent investment.

#116965 Why Are Some Glazes Nicer To Deal With?

Posted by JBaymore on 23 November 2016 - 08:56 AM

Commercial glazes can have clay/s, gums, or other additives to keep them uniformly dispersed. Although I cannot prove it, I have long held the suspicion that they are also using a dispersing agents.

Nerd

 

Yup.......

 

There are two distinct parts about studying glazes........ ONE is molecular formulas.

 

But the OTHER ... and often overlooked side.............. is the materials sourcing.  (remember packing density?)

 

BOTH have an impact.

 

The second part there has a huge influence on 'what's in the bucket'.

 

We can ALSO adjust a lot of what is in the bucket... by organic additives... that do not remain after firing.

I usually retire in a kiln. I have scraped it off.

 

I know a lot of people seem to like to retire to a warm place.  But I prefer a cooler climate.  :D

#115561 Chawan, Yonomi, Tea Bowl, Tea Cup, Mug.......

Posted by JBaymore on 02 November 2016 - 10:04 AM

"i've lately been questioning the tea pot too. is the traditional design still the best design for today................"

 

There are and have been many designs for teapots...... not just one.  Serious tea drinkers tend to select the pot to go with the tea type.  Some people use tea bags... some use loose tea.  Some drink Lipton... some drink $100 an ounce olong.

 

There are lots of options for teapots.  Learn about tea........ and you can learn about making teapots.

 

If you are trying to make XXXXXXX to use for XXXXXXXX, you either need to know a decent amount about XXXXXXXXX or have a good advisor that does know about XXXXXXXX that can help you understand what the important factors are about the way the piece gets used for XXXXXXXX.

#114662 Concerns About Wood/anagama Kiln Smoke Vs Neighbors...

Posted by JBaymore on 13 October 2016 - 02:07 PM

The anagama that I designed for our college can be fired totally smokeless as well as flameless at the top of the chimney without any active afterburners or any mechanical support systems.  This CAN be done.  It just requires and understanding of combustion theory, a bit of fluid mechanics, and having a budget to support it. 

 

gallery_1543_1143_321911.jpg

 

"Traditional" anagama-style kilns smoke because they are basically old, outdated, and primitive combustion designs from about 900 to 1600 AD.  You do not need that choo-choo smoke to get good results.

 

Just about ANY style of wood kiln can be made to be smokless if you adjust the design parameters.  Note that this does NOT address the particulates in the PM 10 and PM 2.5 and down range.  They are still there.... you just can't see them.

#114405 Qotw: Are You Ransacking Trash Bins?

Posted by JBaymore on 07 October 2016 - 09:32 AM

I'm in the point in life that, like maybe Mark and Pres, I have stopped acquiring stuff "that might be good some day" in the studio.  Too many years doing that are already behind me. 

 

At the moment, I am working on streamlining my studio space and getting RID of stuff that is not sort of actively used.  Example: I've decided that I will no longer do any workshops out of my own studio... so I'm selling off about 4-5 wheels that I don't need.  Some plaster molds that I no longer use....... going away.  The "too heavy" thicker wood ware boards that are still absolutely perfectly useable.... but not nice and light like my brich ply ones....... so I don't tend to use them....... going.  And so on.

 

If I see something that will fill an IMMEDIATE need...... I would not be above "dumpster diving".... but I am not actively looking (like I used to).

 

However... that being said....... a dumpster full of new-ish insulating firebrick......... I'm all over it  ;) .

#114403 Starting An Indiegogo Campaign...and Not Sucking At It

Posted by JBaymore on 07 October 2016 - 09:19 AM

 

 

Your next hire should be someone with successful experience in fund-raising/donor development for non-profits.  No clay experience needed, just good non-profit business and fund-raising acumen.

 

I've sat on 3 non-profit Boards.  This stuff is NOT easy.

 

They can hire Lee as a consultant.  She has experience in this kind of stuff (as you can tell from her post above).

Custer has been all over the map almost bag to bag for a couple of years now.  It is an issue.
