Dani 1 Posted March 12, 2017 Report Share Posted March 12, 2017 Looking for a white speckled glaze. What ingredient create the speckling? Quote Link to post Share on other sites
neilestrick 4,456 Posted March 12, 2017 Report Share Posted March 12, 2017 You could try a granular manganese or iron, but they may bleed out and/or discolor the white. It would be easier to use a speckled clay body with any white glaze. D.M.Ernst and preeta 2 Quote Link to post Share on other sites
rakukuku 122 Posted March 12, 2017 Report Share Posted March 12, 2017 Maybe illumite? We have one speckled green glaze that uses it. Speckles are black. Quote Link to post Share on other sites

preeta 207 Posted March 13, 2017 Report Share Posted March 13, 2017 dani what cone are you looking for? ^6 or higher? or lower? in my limited experience i have not really seen many speckled white ^6 glazes. i havent seen them in the studio, neither at ceramic shows. ^10 i have come across quite a range of them. in all sorts of white. cool whites. warm whites. not just at studios but also people selling gas fired ware. i agree with Neil. I really enjoy playing with speckled clay and then using slip and transparent glaze; and also two coats of white glaze. D.M.Ernst 1 Quote Link to post Share on other sites
fergusonjeff 45 Posted March 13, 2017 Report Share Posted March 13, 2017 I use a lot of Laguna Speckled Buff (#403 I think) at cone 6. The granular manganese gives great speckles through any glaze I have used. I got really nice speckled white using this clay and Van Gilder's waxy white glaze recipe. The glaze is usually clear/tan in a uncontrolled cooling, but is a nice speckled white using a controlled cool. Quote Link to post Share on other sites
Chilly 877 Posted March 13, 2017 Report Share Posted March 13, 2017 http://www.rabcospecks.com/shop/Glaze%20Crystals%20Store/ Specks and "crystals", I don't know anything about these but they look interesting. I didn't see any cone/temperature guidance! A UK supplier lists similar, but does say for low firing only (or some were - can't remember, but do know the ones I wanted would not work at ^6).

I contacted them about this. Waiting to hear back. So far pretty bad customer service. Quote Link to post Share on other sites
Dani 1 Posted March 13, 2017 Author Report Share Posted March 13, 2017 One of the old commercial glazes I inherited was called Speckled Bone. Maybe the only way to get a speckled glaze is to buy a commercial one? Quote Link to post Share on other sites
flowerdry 131 Posted March 16, 2017 Report Share Posted March 16, 2017 I have had some good results with bisquing some brillo pads, then sprinkling the fine powder over wet glaze. Shows up really nicely in white glaze and you can speckle heavily or lightly as it suits you. If the glaze dries too much before I can make the particles stick, I just mist the area with water. I suppose you could just mix the powder into the glaze and apply it that way. Quote Link to post Share on other sites

CactusPots 241 Posted April 16, 2019 Report Share Posted April 16, 2019 A good source for granular iron for this purpose is car repair shops that do brake jobs. They literally have buckets of brake drum lining grindings. A coffee can full is a lifetime supply; Quote Link to post Share on other sites
chiznar77 1 Posted January 27 Report Share Posted January 27 Making a colored glaze and sintering, then adding that to a base glaze will give you a lot more control https://www.oldforgecreations.co.uk/blog/glaze-sprinkles LeeU 1 Quote Link to post Share on other sites
