docweathers Posted February 10, 2015 Report Share Posted February 10, 2015 I really like the color that Wrights water blue gives but I'm consistently getting crazing. I've read that this is fairly common with this glaze. wright’s water Blue glaze (Cone 1–6., oxidation) Lithium Carbonate . . . . . . . . . . . . . . . 3 % Strontium Carbonate . . . . . . . . . . . . . 9 Ferro Frit 3110 . . . . . . . . . . . . . . . . . . 59 EPK Kaolin . . . . . . . . . . . . . . . . . . . . . 12 Silica . . . . . . . . . . . . . . . . . . . . . . . . 17 100 % Add: Bentonite . . . . . . . . . . . . . . . . . . . 2 % Copper Carbonate . . . . . . . . . . . . 5 % Has anyone worked out a modification that prevents the crazing... a better fit to G mix 6 Link to comment Share on other sites More sharing options...
Babs Posted February 11, 2015 Report Share Posted February 11, 2015 Think advice in the past has been to add silica in 5% amounts and test.... Don't know the clay you're using, or the glaze but may be worth running a line of additions of silica to see.. Cone 1 -6 what's going on there??

docweathers Posted February 11, 2015 Author Report Share Posted February 11, 2015 I will give it a try. I was being lazy hoping someone else had done the hard work. Link to comment Share on other sites More sharing options...

vkpyle Posted October 5, 2015 Report Share Posted October 5, 2015 I've been getting blistering and pinholing with Wright's water blue, and have had a couple instances of pieces whose insides are glazed in WWB and outsides in something else, cracking during cooling. Would love any advice. I'm addicted to WWB color, but having problems with certain applications. Dipping seems fine, but pouring and painting have a hight failure rate for me.

PeterH Posted October 6, 2015 Report Share Posted October 6, 2015 Love hi-alkaline copper glazes from raku. However according to: http://insight-live.com/insight/share.php?show=rXwWeKb18ygrqF97vhcFjRrJX5y5Pi1RNrst8cF9ZXLArKEKDQXitEKruY3muruhJ1rxG2tePAcgE [This glaze] Has a very high calculated expansion, the degree to which it crazes is thus no surprise. There is even crazing on a 40% silica porcelain. Which suggests that this is not a minor mis-fit issue, and that stopping the crazing might be difficult. PS Another "water blue" which claims to be reformulated "to avoid crazing". https://uk.pinterest.com/pin/103442122666691983/ ... but the colour is cyan.

oldlady Posted October 6, 2015 Report Share Posted October 6, 2015 doc, why not try Rutile Green from bill vangilder? i think it is also in mastering cone 6 glazes. use the base glaze and some cobalt carb for a nice blue. someone is asking about a commercial glaze that looks like it in a different thread about blue hare glaze. see the picture there. that base glaze takes many colors and they all look great.

oldlady Posted October 6, 2015 Report Share Posted October 6, 2015 make it thicker by letting some of the water evaporate. van gilder made it to go over his other colors so it was thin as mixed but works fine if allowed to evaporate. Link to comment Share on other sites More sharing options...
Min Posted October 6, 2015 Report Share Posted October 6, 2015 That second Water Colour Blue recipe still is high expansion, 8.13 I think it will craze on most clays. Ferro C-292 stain is pretty close to that colour, have you tried using a stain and a clear that fits your GMix6? Sallieg T, hairspray works too. No harm to the glaze.
