New recipes I would like to try. Ideas or advice?

[Luca]

I bought the different dry raw materials and a precise scale, for this reason this time I weighed the ingredients precisely. However, I still use a very dense ash slip instead of dried ash: drying the ash would be too much work at the moment.

I'm preparing the basic recipes for the next experiments. For now I have prepared the first two recipes based on the first experiments: 

First recipe: 

- 1 kg potassium feldspar 

- 1 kg ball clay 

- 170 gr bentonite 

- 500 ml pheatine 

- 2 liters of water 

- 4 kg dense ash slip

Second recipe: 

- 1 kg potassium feldspar 

- 1 kg china clay

- 170 gr bentonite 

- 500 ml pheatine 

- 2 liters of water 

- 4 kg dense ash slip

I'm looking for other simple basic recipes to try. Something that can introduce someting new for the experiments with oxides. For this reason I looked to my books searching ideas. 

Ideas or advice are very wellcome!!!

I have tried to modify some recipes of "Glazes cone 6 1240°C" book of Michael Bailey: exchanging whiting with wood ash, dolomite with wood ash and talc, exchanging soda feldspar and litium carbonate with spodumene, adding 5% bentonite for single firing. I am trying to modify a cone 8 recipe of the book "colour in glazes" of Linda Bloomfield exchanging soda feldspar with spodumene and calcium borate frit with colemanite, exchanging whiting with wood ash and using a litle less quartz hoping to fire successfully at 1240°C instead of cone 8.

Looking to my books these are some ideas to try:

Recipe 3 (recipe T13 modified from Michael Bailey book): 

830gr soda feldspar, 130 china clay, 140 bentonite, 430 quartz, 120 Zinc oxide, 1,5 kg wood ash dense slip. And pheatine.

Recipe 4 (recipe T14 modified from Michael Bailey book):

1kg spodumene, 500gr china clay, 160 gr bentonite, 500gr dense wood ash slip, 100gr talc, 100gr zinc oxide, 240gr quartz.

Recipe 5 (recipe OR1 modified from Michael Bailey book):

1kg spodumene, 130gr china clay, 150gr bentonite, 322gr bone ash, 16gr litio carbonate, 362gr talc, 244gr quartz

Recipe 6 (recipe for chromium green modified from Linda Bloomfield book):

1000gr spodumene, 320gr colemanite, 1000gr dense wood ash slip, 107gr china clay, 300gr quartz, 107gr bentonite.

I hope to use this recipe with chromium to obtain a green glaze.

Pheatine paste may itself be bentonite and water.

Fire some pheatine paste by itself. If it leaves no trace, it is an organic suspender rather than mineral like bentonite.

Smcetites like bentonite contain fluorine which is an important flux, without which ash glazes may not do much at cooler cones.

Thanks

I'm trying to use only a little of pheatine. The shop that gave me it said that can have a little of flux effect.

In my first experiment I did not use pheatine and the glazes were quite good.

I fire at 1240°C: I think it can be between cone 6 and cone 7. Very near to cone 7 probably.
