Min Posted August 27, 2014 Report Share Posted August 27, 2014 Nice.Thanks Min Not familiar with Bentolite,,,Bentonite? Bentonite L a form of? It's just a white firing bentonite, any bentonite should be okay in this recipe. Link to comment Share on other sites More sharing options...

ayjay Posted August 27, 2014 Report Share Posted August 27, 2014 This looks about right to me. http://fetishghost.blogspot.co.uk/2010/03/cone-6-amber.html This is worth a look too, ( it's not amber) one day I'll have a go and see if I can repeat it. http://fetishghost.blogspot.co.uk/2010/03/cone-6-bonemarrow-glaze.html Link to comment Share on other sites More sharing options...

Total 105.4 but the Mn and Fe are additives, right? and i'm asking if the bentonite is also an additive before I convert to percetages prob going to consider these 3 in this light. Just wondering how you approach this. Link to comment Share on other sites More sharing options...

Hi Babs, Since there is a fair amount heavy sinking material, (frit, silica, nepsy plus the spod) I added the bentonite to the base and kept it as a "static" ingredient when working out the formula then rejigged it to add up to 100. I worked on the base first then figured out the colourants that's why the bentonite is in the base. I'll redo the recipe if you like to have the bentonite as an additive after the 100 base but it will leave you with a lot of decimal points with the base ingredients. Doesn't matter to the glaze where you put the bentonite, chemical formula will be the same. Link to comment Share on other sites More sharing options...
Babs Posted August 29, 2014 Author Report Share Posted August 29, 2014 Thanks Min, I have been learning,slowly from books the chem. of glaze formulas but still do not know enough to be confident in these matters. You're right, many decimal points the other way. Will be testing the glaze on tiles/small pots very soon. I was reconstituting a glaze which had totally dried out in bucket. On sieving, part of the glaze slurry would not go thro' the sieve after many run through and watering down. Will be testing that too. Had any experience with this? Obviously the resulting suspension in my bucket now is lacking in something. Don't hae the recipe here but just wondring whilst a t the keyboard.

You could try taking the stuff that doesn't go through the screen and heating it up in some boiling water to see if it will dissolve. I would guess it's some soluble stuff that has crystallized in the dry bucket. Link to comment Share on other sites More sharing options...
Babs Posted August 30, 2014 Author Report Share Posted August 30, 2014 Thanks I'll do that in the future, this gunk is now in the dispose carefully bin, I posted this as a separate question, but am remembering now that Tin may do this ie crystallize in the bucket. I also posted the recipe in the other post. Thanks for your help Min. Link to comment Share on other sites More sharing options...
Min Posted August 31, 2014 Report Share Posted August 31, 2014 Babs, I noticed in your other post that you are looking for an Oz equivalent for 3195, do you want me to redo my recipe to get rid of the 3195? Link to comment Share on other sites More sharing options...
Babs Posted August 31, 2014 Author Report Share Posted August 31, 2014 That would be great1 I just trialled not fired yet a little sub ing an old no longer produced colemanite frit, just for fun but noted that the 3195 is pretty high in Boron and Calcium?? From above, I inherited a few supplies, some one cleaning their space to clutter mine! And I chucked out a light coloured substance labelled bentonite so there you have it prob. was Bentolite but I had never encountered this, looked more like dolomite, didn't reaact in water the same as Bentonite does when I dropped a bit in. Oh well, earth to earth etc. Link to comment Share on other sites More sharing options...
Min Posted September 1, 2014 Report Share Posted September 1, 2014 Yup, 3195 is high in boron and calcium. I got rid of the bentonite in the altered version below, there is 25% EPK in it now so I don't think you will need the bentonite. Chemistry is fairly close, I included the unity formula, expansion figures etc so you can compare the two. I think it looks okay on paper but you have to try it on a test piece to be sure. new version with no 3195=========================================EP Kaolin................... 25.10Silica...................... 22.803134........................ 20.90Australian Spodumene........ 12.80Dolomite.................... 13.10Nepheline Syenite........... 5.30=Manganese Dioxide .......... 3.00=Iron Oxide Red.............. 2.00=========105.00CaO 0.44* 8.73 9.98Li2O 0.10* 1.03 2.22MgO 0.21* 3.06 4.86K2O 0.01* 0.36 0.24Na2O 0.13* 2.85 2.95P2O5 0.00* 0.09 0.04TiO2 0.00 0.10 0.08Al2O3 0.41 14.78 9.29B2O3 0.21 5.09 4.69SiO2 2.76 58.52 62.42Fe2O3 0.04 2.22 0.89MnO 0.00* 0.00 0.00MnO2 0.10* 3.16 2.33Cost: 0.24Calculated LOI: 9.64Imposed LOI:Si:Al: 6.72SiB:Al: 7.22Thermal Expansion: 6.25Formula Weight: 283.24 Original version with 3195=========================================EP Kaolin................... 14.00Silica...................... 23.00Frit 3195................... 16.60Bentolite L................. 2.003134........................ 4.80Australian Spodumene........ 15.00Dolomite.................... 15.00Nepheline Syenite........... 10.00Manganese Dioxide .......... 3.00Iron Oxide Red.............. 2.00=========105.40CaO 0.40* 7.87 8.95Li2O 0.11* 1.20 2.56MgO 0.25* 3.51 5.56K2O 0.02* 0.55 0.37Na2O 0.12* 2.61 2.69P2O5 0.00* 0.06 0.03TiO2 0.00 0.06 0.05Al2O3 0.40 14.50 9.07B2O3 0.21 5.14 4.71SiO2 2.80 59.24 62.87Fe2O3 0.04 2.13 0.85MnO 0.00* 0.00 0.00MnO2 0.10* 3.13 2.30Cost: 0.22Calculated LOI: 9.08Imposed LOI:Si:Al: 6.94SiB:Al: 7.45Thermal Expansion: 6.11Formula Weight: 284.07 Link to comment Share on other sites More sharing options...
