In Topic: Fritware?

Yesterday, 02:26 PM

No idea, I would think they are with those kind of price differences. Adding 33% to clay body or 70%+ to a glaze for the examples supplied in the fritware article just seems like a lot.

 

I may look more into a cone 6 move as anything from 1-5% addition seems reasonable as I can see it like a cheap colourantish thing.

 

Sorry for taking this a little off course.

All my feldspars, kaolin, silica, whiting, dolomite cost 0.70~ per kg and the cheapest frits I can find cost 4.00 per kg minimum for what they call 'standard borax frit'

 

The only ferro frit I can find is 3110 at 6.14 per kg.

 

I didn't think about element life too much and probably don't have enough experience with kilns to make a good opinion :D I just feel its slightly 6 or two threes. Reducing cost in some places increases it in others. No AC needed in the UK, especially up in Newcastle.

Just read an article about this in Sept 15 Ceramics Monthly issue, I get mine late in the UK, only delivered yesterday. Seems like an expensive way to make clay bodies but I get the idea. 0.4% absorption at cone 04.

 

He talks a lot about the ecological impact of firing to cone 10, I'm not sure about that, surely using a frit comes with its own energy consumption already being pre-melted. In the long run are you really saving that much energy? Maybe I love firing cone 10 a little too much. I have always thought about dropping to cone 6 but the ingredients seem to be 4-5 times as much to get glazing going so does it really save money in the end. Probably but I don't like it :P

 

I would at least try it out guinea, you never know, it might work for you.

In my school science department we had two teachers, one called Mr Dick and the other, Dr Ball... Not quite sure how Mr Dick ended up with that name but it was endless fun at school being able to call him that legitimately. I did always feel sorry for the higgenbottoms, not the best name to have.


In Topic: Proper Reduction Firing Schedule

27 August 2015 - 03:43 PM

The only time I fired reduction I stayed in reduction from 1000c cone 06~ and kept it there till the end. Are you saying it doesn't really make a difference after you have reduced it for 45 min at cone 08~?
