Topics I've Started

Reconstitute?

08 December 2014 - 12:29 PM

I have yet again started the tedious task of reorganizing my studio. This time I really think Ill have things in the best possible place. One of the many things that gets rediscovered is the large box of old glazes that Ive stashed under my work table. Like many that have gotten things used in the ceramic world I received a plethora of stuff when I first got my used kiln. All I really wanted was the kiln! But it came with so many molds and glazes. Molds/moulds were disposed of but I know that many dislike the idea of dumping toxic glazes just anywhere. SO Ive kept them and when things move I just push the box into another space. This time I took more notice of some and realized they were underglazes that went to ^6. Being that has been my target range I sifted through them all and took out those alike. I never really noticed before because I knew the old lady that once operated the stash of goods didnt fire midrange let alone high fire. So like the moulds I separated out those that I thought Id use here and there over time and mentally bid goodbye to the rest.

 

Most of them are Ceramichrome Beauty Flos ^06-6. Like many of the glazes they seem to be like a scotch thats old enough to order its own scotch. Any think they still might be of use? Some are not fluid, some are. Reconstitute with water?

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?
