Babs Posted December 9, 2020 Report Share Posted December 9, 2020 Wondering what the closest frit/frits substitute would be for Fero 3134, Aus 4108 would be. Link to comment Share on other sites More sharing options...
neilestrick Posted December 10, 2020 Report Share Posted December 10, 2020 Nothing direct, usually easiest to reformulate with Gerstley/Gillespie borate. Ferro 3195 has similar boron levels, but it's going to put other things out of whack. What do you have available as a boron source? Link to comment Share on other sites More sharing options...
liambesaw Posted December 10, 2020 Report Share Posted December 10, 2020 Gerstley was difficult for me to sub in, and the resulting glaze was nothing like the fritted one. It has too much magnesium I think. Worth a try though if you can't get some 3134 Link to comment Share on other sites More sharing options...
Babs Posted December 10, 2020 Author Report Share Posted December 10, 2020 I can ordr in but have ample supplies of 4712/4113 4103/4616 3110/4110 3124/4124 1212/2244 But know Ferro uses different numbes for US.. And straightGerstley borate Firing to cone 5-6 You guys seem to use 3134 a lot Link to comment Share on other sites More sharing options...
liambesaw Posted December 10, 2020 Report Share Posted December 10, 2020 If you have 3124 you can pretty easily balance it by adjusting some alumina out of the rest of your recipe. 3134 is pretty much 3124 but with no alumina Link to comment Share on other sites More sharing options...
neilestrick Posted December 10, 2020 Report Share Posted December 10, 2020 The problem with using 3124 is that it's going to drop down the amount of clay in your recipe, possibly enough that it affects suspension and application. You'll just have to run the numbers and see how much it affects your particular glaze and decide if it's worth it. The primary benefit of 3134 is that it's high in boron and low in alumina, so you can get all the boron you need without sacrificing any clay.

Callie Beller Diesel Posted December 10, 2020 Report Share Posted December 10, 2020 3134 and 3124 were used to reformulate recipes that use gerstley borate/colemanite/ulexite. The gelling and the flaking and the solubility and the LOI being issues in the natural sources. Link to comment Share on other sites More sharing options...

From Glazy, 4108 as the first chart below and 3134 as the second. Do you use 4108 as a sub for 3134? Wasn't sure if I was reading this as you use 4108 as a sub for Ferro 3134.

Ferro 3134 Yes as the company doesn't do 3134 for Aus anymore just 4108., or uses different numbers here... Same as in original post, I gave what is common subs for original frits available. In general sub as I have a lot of other frits but will order 25kg bag if mo sub. Not looking to repeat exact glaze effect but don't want to b. Up totally!

Min Posted December 10, 2020 Report Share Posted December 10, 2020 I played around with what you have available and came up with a possible sub using your ingredients for 3134. It's not exact, main differences are: there is magnesium in it whereas the 3134 doesn't contain that, sodium and calcium is a titch lower but with the magnesium this should offset the lower flux amounts of those. LOI goes from 0 for the 3134 to 15.2 (but this is still about 1/2 of what it would be to just use gerstley alone) Boron, alumina and silica are equal. You could mix up 100 grams of this blend and try it 1:1 for 3134 in a test recipe and see how it comes out. Magnesium might make a difference or might be inconsequential. I'ld probably just round off to the tenth decimal point. (if you don't have wollastonite let me know and I'll redo it with calcium carb but the LOI will go up some more) Link to comment Share on other sites More sharing options...
