docweathers Posted August 9, 2017 Author Report Share Posted August 9, 2017 Yes that it the crawl I want. The trick is getting it to stick on vertical surfaces.. which I have done, but with difficulty. Link to comment Share on other sites More sharing options...
glazenerd Posted August 9, 2017 Report Share Posted August 9, 2017 Nice piece. I had no problems with it sticking. In fact, bonded pretty much like any other glaze. It does not crackle until you fire it, it is smooth during application. Works much better if you dip it. Just needed some Nerd Suspender is all. Let me test it a few more times, and will post the procedures. Link to comment Share on other sites More sharing options...
perkolator Posted August 10, 2017 Report Share Posted August 10, 2017 Our students use crawl glazes on vertical surfaces all the time. The work is lifesize and being made by 18-20-something year old undergrads with no prior ceramics experience...and usually once-fired to ^04 I've noticed the key to getting crawl glazes to stick is to water it down and build up the surface in layers...or spray it on. We definitely use CMC gum, which helps as a binder, and trying to not mix the glaze too far in advance seems to help too. The students have found many crawl recipes over the years but for the most part they're using: SDSU crawl, LW Lichen, 3rd Degree Burn and whatever experiments they choose to do.

docweathers Posted August 29, 2017 Author Report Share Posted August 29, 2017 I tried most of the suggestions that were offered. By far the most effective was the suspender that Glaze Nerd sent me. It works far better than the bentonite that I had been using. Even with very thick layers of Lalone Crawl, the glaze remained solidly fastened to the bisque and just developed the fine cracks that are necessary for the crawl.

Do we get the see the fired results? Link to comment Share on other sites More sharing options...
docweathers Posted August 29, 2017 Author Report Share Posted August 29, 2017 Yes, as soon as I do a glaze firing.... which will be a while. Link to comment Share on other sites More sharing options...
neilestrick Posted August 30, 2017 Report Share Posted August 30, 2017 Yoshi did great work with crawl glazes. I've got a friend who was a student of his- I'll see if he has his recipes. Link to comment Share on other sites More sharing options...
neilestrick Posted September 1, 2017 Report Share Posted September 1, 2017 I heard back from my friend. He said all he knows is that Yoshi used EPK, talc, magnesium carb, and zircopax, and that he never measured anything (at least not in a way that made it repeatable for anyone else). He was a 'scoop of this, pinch of that' kind of guy. I'm sure he knew what he needed and was measuring in his own way. Link to comment Share on other sites More sharing options...
