Topics I've Started

Two Black Mason Stains

16 October 2014 - 02:50 PM

So being Im broke and trying to work with what I have Im going to try a few different avenues. I have a ton of Highwaters orange stone. I also have some local clay Im going to use as a slip, terra cotta color of course. So anyways I wanted to just utilize what I have and contrast a bit between the different tones of earthenware colors with some white and black accents. I have some Bringles all purpose slip that I mixed up a while back as my "white" inclusion. I recently picked up two 1/4 pound portions of Masons Best Black Stain and their Onyx Black Stain to trial run with. I was wondering has anyone used that slip recipe as a good base for stain inclusions?

 

The recipe I used was:

 

EPK 20
OM 4 20 -or XX Saggar
Neph syen 25
Silica 30
Gerst Bor 5
Bentonite 2

 

+10% Mason stain

 

I also considering using this as my clear glaze, considering it fits well in the end. Got it from digifire. I liked their remarks of its over all strength.

 

Plainsman Cone 6 M370

neph sy 18.30

ferro frit 3134   25.40

epk 19.60

wollan   6.90

silica  37.60

talc   2.3

 

Just trying to find recipes that have what I have, sometimes it seems like a good choice then I realize Im missing the last ingredient. In my limited knowledge Im not sure if Ill have issues with the black stain slip. I know Ive had Amacos black underglaze go blue because of the cobalt. I thought of formulating a black slip because I have more Manganese Dioxide than anyone really should but I dont feel comfortable with the "dangers" and questions as to whether its food safe etc.


Sand Blasting Media?

11 October 2014 - 03:55 PM

So Ive been cleaning up my studio a bit and trying to get more productive these days since I left my job at the end of august. Being I dabble in some metal work with lost foam casting etc Ive come to realize I have a good amount of sand blasting sand that Ive used for investing my foam work. Its Black Diamond brand and a 30-60 mesh if Im not mistaken. I was curious if I could use it as a grog? From what I found out about the brand is that its a "low silica" media and comes from coal slag. I fire electric so would this possibly be bad for my elements if I were to add it to a clay body? I used the search function and it doesnt seem like a topic thats been covered before. Just thought Id throw it out there. Google only brings up pages about industry uses for coal slag. Am I wrong to think that the firing to ^6 the slag might emit too much carbon for my kiln?


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

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.
