Topics I've Started

Small Kiln Option

16 May 2014 - 01:50 AM

So Ive been teetering back and forth on this idea. Ive been wanted to mess around with some more glass by testing out some glass clay medium. Kinda like Pate De Verre but doesnt need a mold. Frit to me can get costly and being I work in the restaurant business I have plenty of access to glass for experimenting. Ive dont pot melts etc so far so this is the next step. The glassy clay technique utilizes powdered, if not very small, frit. Ive used a crusher and well....its a pain in the butt. So Ive been looking at some small kilns to use as a glass melter/test kiln. Reason being in my search for easier ways to make frit I stumbled across this pic on Paragons site.

Even though she is making stringers or rods of glass I thought why not flip and have a small kiln, with the use of ceramic fiber board, like this to make frit. Even if the glass is slow and gradual it will still create "dutch teardrops" that when the glass tails are broken will burst into powder. So you have the kiln, lid removed, flipped onto some fiber board with a pot melt during firing, then dripping into a container of cold water. Beats the slow process of heating, not too mention the purchase of a crucible(s), of glass in a kiln, then pouring it into the water. I thought about using one of my kiln sections and fiber boarding the top and bottom to accomplish this, but the cost of that might just make it worth while to just buy a kiln. Which in turn I could use for glaze testing etc. It seems shes (in the photo) using the Paragons Caldera Kiln. Its in a modest price range. Im not sure if I covered my bases but since its late Im going to leave it at that.
 

 

 


Raw Materials Start Up

17 March 2014 - 12:40 PM

So I ordered a bunch of stuff from Axner recently and Im curious what those with a full inventory of raw materials would advise me to purchase on my next go around. I have been wanting to do a darker bodied clay and Im going to use this recipe. Cone 6

 

Red art                  40

EPK                       18

OM4                      15

RIO                        16

Maganese Diox      6

Neph Sy                 2

Bent                        3

 

The recipe called for a Kaolin so being I already had EPK I figured Id give it a go. The glazes Ill be testing is...using just the soda feldspar instead of kona. Cone 6

 

Ball clay               40

Ferro firt #3124   30

Wollastonite         25

Dolomite               5

 

F-4 Feldspar              46

G. Borate                   30

EPK                           13

Silica                         11

 

Kona F-4 feldspar         50

Wollastonite                  20

EPK                               10

Silica                             10

Gerstrate Borate            10

 

Being my main direction at the moment is cone 6 and utilizing the color of the clay body primarily and surface decor. I didnt go out of my way for colorants and some things I bought just because they seemed common ingredients. I also use bentonite in green sand metal casting. The frits are for glass/clay surface testing. A thread recently sparked my interest a bit. So heres the list. all in pounds.

 

 

 

Ball Clay - OM-4 (sold per lb.) 50

Ball Clay - XX Sagger (sold per lb.) 50

Bentonite - 325 mesh (sold per lb.) 25

Calcium Carbonate (Whiting) 325 Mesh (sold per lb.) 50

Dolomite (Dolowhite) (sold per lb.) 25

Feldspar - Custer 200L (Potash) (sold per lb.) 50

Gerstley Borate (sold per lb.) 50    

Iron Oxide - Red Spanish (sold per lb.) 15    

Kaolin - EPK (Edgar Plastic Kaolin) (sold per lb.) 50    

Manganese Dioxide 325 Mesh (Morrocan) (sold per lb.) 25    

Neph Sy 25    

Red Clay - Red Art (sold per lb.) 50    

Rutile - Milled Ruflux 61 (sold per lb.) 2    

Rutile - Granular (sold per lb.) 2    

Ferro Frit - 3110 (Lead Free) (sold per lb.) 10    

Ferro Frit - 3124 (Lead Free) (sold per lb.) 10    

Ferro Frit - 3134 (Lead Free) (sold per lb.) 10    

Ferro Frit - 3195 (Lead Free) (sold per lb.) 10

Feldspar - Minspar 200 (Soda) (sold per lb.) 50   

Wollastonite Vansil W-20 (sold per lb.) [SHIPS OH] 50  

Darvan #7 (Dispersal) (Liquid)

Size: 1 pint

 

Any recommendations for my next bulk order? Im sure I bought too much of somethings at the moment, but when I found out that the pallet shipment would drastically reduce my shipping cost I decided to buy bigger.


Up Cycling Old Glaze

06 March 2014 - 04:03 PM

So I've been dabbling in glass as of late since clay is on hold due to atlanta clay being unable to obtain the raw materials I need. Mainly because of the weather. Fed up with that I was happy that axner has all I need. 600lb order coming Monday :) so im in need of space. Being I have a ton of low fire glazes from when I bought my kiln I'm now looking at ways to dispose of them. I've been successful with glass melts in plaster/silica molds and was curious about firing my glazes in them then turning around to crush them down for colored frit or even melt them into usable shapes. I know I might be getting into a mess of different co efficients. I did a test already but goofed and had a nasty over flow. I'd propose this to glass forum but have found they shy away once clay content is mentioned. Yet after a glaze is fired it is essential all glass correct? I would like to hear others opinions on my idea. Not recycling , nor disposing, but repurposing.

Green House Next To Kiln Room

23 January 2014 - 12:59 AM

SO I recently fabricated a green house to tie into my pole barn where my studio is at. I guess I wasnt think thinking when if came to where my kiln room was at and where the exhaust would go. The arrow points to where my kiln is inside and the exhaust comes out from that area. I have a ventilation fan there to help with any fuming. I had worried recently that maybe the fumes might pose a danger even the green house is sealed to a point. The vent windows are on the far right wall which you can see in the photo. I have been wanting to use a dark cone 6 clay that contains Maganese Dioxide and I know the fumes are toxic. I was curious about if the position green house over all could present a danger? The green house will be for a aquaponics system where there will be an open fish tank and grow beds. Like I said the greenhouse is sealed in the sense that fuming really would have to try hard to get in. Still though I question could it pose a problem especially with growing edible food.

Cone 6 Clay Body

18 September 2013 - 04:17 PM

So here is where Im at now. I have stock of EPK, bentonite, red IO, and (being I live right next to a Mica Mine) access to mica. I know mica has little significance in a body, but I just like it for the flecks. From what Ive read I like what Wollastonite can do for both bodies and glazes so I would like that to be an addition to my body. My direction is more than likely going to be making tea pots or other vessels. SO I guess really Ive been searching for a recipe that would mature nicely at cone 6 and would hopefully have more character if it were to lack having a glaze.

 

The Bizen and Shigaraki bodies have such an attractiveness to them yet I doubt that can be attained at cone 6 in an electric kiln. Ive always liked how clays change their look the higher you fire, but Im only wanting to go as high as cone 6. I also have been falling in love with more iron rich clays and drifting away from the buff white clays.

 

I have rewritten this post multiple times and having trouble conveying what Im looking for...I think. So am I in the ball park?

 

Red Art (or red natural clay, low workability)

EPK

Red IO (maybe the addition for a darker clay)

Wollanstonite

Mica (if natural clay is not to be used)

Ball clay (if natural clay is to be used)

 

Red IO and Wollanstonite are fluxes right ? so keep their percentage at a maximum of 25 %? And the rest filler?
