Sculpey strength?
Hi all. I was thinking of making a 3d sculpture that will eventually be
wall mounted. I am currently leaning towards using a oven bake clay such as sculpey. My question is having never used it I am concerned about the strength, in terms of fragility. The piece will not be handled and will be mounted and framed. Also if anyone has any suggestions as to clear coat or clear strengthening agent please feel free to mention them. Thanks. |

Sculpey clay is the most fragile of the polymer clays. THe bulk white
original Sculpey is the most fragile of the Sculpey clays. "Jason" wrote in message news:qteXc.9579$VY.8086@trndny09... Hi all.

Would it still serve my purpose? The sculpture will be relatively flat and as I said wall-mounted so it will not be touched or in heavy traffic. I guess I'll have to bake a piece and judge for myself. |

I guess I'll have to bake a piece and judge for myself. I tend to think of it as about the same strength as plaster; not suitable for a lot of unsupported detail, though it shows detail well. Haven't used it in years but the last things I used it for were well-supported bas relief pieces. There's one on my site; Sand Witch, on the Bare Inspirations page.

Helen "Halla" Fleischer, Fantasy & Fiber Artist http://home.covad.net/~drgandalf/halla/ Balticon Art Program Coordinator http://www.balticon.org Thanks for the reply. That is along the lines of what I was thinking of doing only maybe protruding a bit more. Are you aware of any other oven-bake clays that are suitable? I have done a few searches and many seem to recommend Sculpey in this category, that's what first set me to using it. I thought of maybe an air-dry clay but I just will not be able to complete the work in one sitting, or day for that matter. Thanks again. |

You could try one of the other polymer clays such as Premo, Fimo, Kato
Polyclay, Promat. Refer to this site for information on the relative strengths of the clays: http://www.glassattic.com/polymer/tests.htm "Jason" wrote in message news:BysXc.12092$Nn2.5012@trndny05...

Refer to this site for information on the relative strengths of the clays: Thanks. I may have to do that. I tried baking a few samples of the Sculpey but it just did not turn out right. I baked it according to directions the first time and a bit hotter the second and in both cases the finished samples were rubbery and had dark splotches and the color changed quite a bit from white to beige with dark splotches all over them. I just bought the clay from a local well-known craft store and just opened it so I don't know why it was not baking properly. I do have an old oven so that may be a factor. |

In a pinch you can strengthen sculpey a little by painting the cured piece with liquid sculpey and re-baking.

Helen "Halla" Fleischer, Fantasy & Fiber Artist http://home.covad.net/~drgandalf/halla/ Balticon Art Program Coordinator http://www.balticon.org Well I tried baking three pieces 1/4" think for reference. All the pieces came out semi-hard after 20min and hardened a bit more after cooling but are not brittle. It is hard enough for the purpose I need but the biggest disappointment is that the color changed a lot. It started as white but is now beige with dark splotches here and there. One was baked at 265F, one at 275F, and the third at 300F all for 20 min and all look the same. I have a very old oven though and I suspect that is the culprit, is what I described a product of over-baking or charring? Also I was under the impression that it would be brittle like glass, instead it is like very hard rubber. Like I said that will work but is that how it is supposed to be? I may take a trip to a local thrift store this weekend in search of a toaster oven to test it in. Thanks |

An oven thermometer is a very worthwhile investment. It also helps to line the tray with cardboard and tent foil over the work. Rubbery is better than brittle, but brown splotches mean too much heat.
