wonderfill is crap. whatever stone it touches, doesnt set. Brian Carson has a method using a flexible magnet strip, pretty awesome.
Isn't that just more expensive playdoh?

Use the wonderformer filled with playdoh.....works great!
Your grand kids may have 3 eyes??im not trying to disparage it, maybe I shouldve used vaseline? Even if I use it to fill a palate on an impression tray, the stone touching it never sets, even if you let it dry.. Its almost strange that they make it for dental stone because Ive never had any luck with it. I let the kids play with it.
I'll admit that I've never used any wonderdoh in production. I tested with the sample packs and wasn't impressed enough with water soluability to pay that much more for it.im not trying to disparage it, maybe I shouldve used vaseline?

With play-doh I don't feel sick throwing it away after each use for contamination issues on alginate. I can't see the utility for the price difference. It's a great idea, but I think it is the selling point of water soluble that is causing the stone softness.Sounds like I may be one of the few here but I like the wonderfill. I use it in combination with there wonderforms instead of bead and box technique.
Now I don't use it on every case. Most cases I just free hand. But I like having it around.
One thing I really like about it is it's easy to show a new tech how to use it and have them pour nice models without making a big mess and lots of clean up on the models.
It's also really nice for blocking out areas you don't want stone to flow. Especially on cast frames around clasp and rest.
As Affinity mentioned it does react funny with the surface of any stone it touches but for me I haven't found it to affect any of the actual working model area. Just seams like the area it touches stays a little softer then the rest of the model. Only the surface though.
Also with its comparison to play dough. I guess in a lot of ways it is similar but one major difference is it doesn't dry out. It's much much more reusable. One bucket last me like 6months plus. Vs play dough I found to not really be reusable. It dries out very easily while your model is curing. It's also a lot stiffer material in comparison to wonderfill.
All just my opinion.... I'm gonna have to look up this magnet strip idea.

I will use a double bead of periphery wax around the impression and then box it in...For filler I do use wonderfill....works great and get far fewer pressure spots. Nice clean casting as well because bubbles rise...I also have the wonderforms but find they are a bit big...But then they are very fast....

Please expound.Man, I am really old school. Been a while, but my favorite and quickest is still the old Plaster and Pumice technique.
Please expound.
