I do not see how long to bake it for the home made clay sculpey clay

eboz64 (author)2017-06-18

Lmbo!!! People on here are incredible. Even after 2 yrs they still make me laugh.....

@drinkypoo - are you on medication? The person who posted this is not Trademark infringing, as 1) this recipe is not being passed off as the original Sculpey clay and 2) there is nowhere on here where this person is asking for money or asking for anything that would induce personal gain. Maybe you should lay off the drinkypoos???

+lgioteno Hey, thanks a lot for this recipe! Helped me in the last minute :)!

Fireworks1082 (author)2015-10-08

This might be a good clay recipe but it's very misleading to compare it to sculpey in any way. I found that it rose and cracked during baking and burned easily. Also it does not have the flexibly of sculpey and would/could not form any small details. For simple projects or for kids this may be a great recipie but I'd suggest something else for anything more complex.

qpig (author)Fireworks10822015-10-08

thanks! I have used a variation of this recipe for years! I put white school glue in with the water in equal amounts. it works well. I also have separated it into smaller amounts & added food coloring...never had a problem.

krafty_momma (author)qpig2016-05-25

Thanks for the tip about adding glue and food coloring into this particular recipe. :)

Sculpey is made from PVC (poly vinyl chloride) with a plasticizer added to it. I met the inventor once. He came to my home and when he and his wife saw how much of the stuff I was working with he told me not to touch it with my hands any more without gloves - and to eat lots of vegetables.

kittenfangs (author)Ninzerbean2015-10-06

Huh? I'm pretty sure you never met the inventor of Sculpey.

Ninzerbean (author)kittenfangs2015-10-07

I was ordering 100 pounds at the time (wholesale) and when the inventor and his wife were vacationing in Ft Lauderdale they saw me at an art show - they recognized the work I was selling was made from Sculpey, I gave them my card and they came over to visit. They were old, the last name started with a Z and that is all I remember besides their comments. I didn't know I would be mentioning it 25 years later and would need proof or I would have taken photos.

Six degrees of separation is all that separates all people on the planet. This, curiously is the average amount of steps a Columbia university study needed to deliver email with 48000 senders and 19 targets. Also, honey combs have six sides and 3 6es are the number of the beast, so therefore email and honey are products of the devil!! ( I love Jeff Beck logic). LOL.

No really, the six degree thing is real. dont really know if honey is satanic, though i doubt it is.

noahspurrier (author)Ninzerbean2015-10-08

I believe you. It doesn't sound implausible.

If you do a search on polymer clays you will find that they are, or at least were made with polyvinylchloride and that the plasticizer had potential endocrine effects. It is extraordinary that people have to be "pretty sure" that someone else's experience is not possible.

loachridge (author)Ninzerbean2016-01-06


Due to a low thyroid condition, I have really bad fingernails-- they are thin and they split. When I'm working with sculpey daily, as I do sometimes, they get wonderfully thick and strong. I know those plasticizers are bad for me, but i sure do like what they do for my nails :/

DonaldG29 (author)2016-05-12

Sculpy, by Polyform Products admission, is PVC product, which was invented in 1960. I have no idea what you are talking about Robert, but you should do fundamental research. I am not sure what the relevance of the invention date of PVC is to the formulation of Sculpy. If you mean that PVC was invented before Sculpy, then you are correct.

marie c (author)2016-03-31

How long and what temperature does this bake at? Is a home oven ok to use?

frcindys (author)2015-12-21


Actually, it IS made from PVC. Please reference this for details: .

Ninzerbean met the inventor of SCULPEY (duh), not PVC. Don't be so judgemental.

I'm making charms to give to kids in my church will this clay work ok?

maxford (author)2016-03-04

Re step 2- "clay ontology silky"- what?? lol

DbudlovJ (author)2015-12-12

do you cook it in the oven to set it? or does it not set hard, like monster clay etc???

Lozchik (author)2015-11-20

Just made a batch. The instructions were really easy to follow. I'll have to try the white glue variation for my next batch when I want to do something a bit more complex then a series of flat shapes. No, it doesn't feel like polymer clay, but for very simple projects/craft time with young children, this may be a good alternative.

cepterbi (author)2015-10-14

Thanks for sharing. I'm sure this'll come in handy in the future for some project.

cepterbi (author)2015-10-14

It is mostly outlawed in the EU?

I guess you are the inventor of european law then. -.-

imzlim (author)2015-10-12

qpig, does the glue change the consistency?

CraftingLoveAroundYou (author)2015-10-11

I'm fairly sure this is more a cold porcelain and not a polymer clay. But it's an interesting recipe for it, as I believe cold porcelain uses glue.

Igioteno (author)2015-10-04

Also a tip is to massage your hands with cream and knead the clay then model without cracking.?

buck2217 (author)Igioteno2015-10-11

Probably should state "handcream" as some of these pedants will say do you mean single. double, clotted,whipped, pasteurised etc!!! ;-)

bethcdh (author)buck22172015-10-11

Absolutely! When I first read that, I made the quizzical face, "Cream? Really?"

MishkaHuskyWoof (author)2015-10-11

How quickly will this stuff air dry? I want to make a C-4 prop for Halloween and this should work perfectly as long as it doesn't air dry too quickly.

noahspurrier (author)2015-10-08

PVC is not outlawed in Europe.

grt57 (author)2015-10-08

Nice Post thanks.

kruth1 (author)2015-10-07

I love this recipe and thank you for reminding me of it. I want to make some Christmas ornaments with my grandson this year but was unsure what to do. I'm going to use this! Again, thanks!

Edgar (author)2015-10-07

A neat Instructable, and eboz64 is right.

eboz64 (author)2015-10-07

WOW! If I didn't know better I'd swear I was reading comments from a bunch of children... I cannot believe adults are so small-minded and spiteful. If you look directly under the comment box you typed in, there is a notice that says "We have a be nice comment policy - Please be POSITIVE AND CONSTRUCTIVE". This is a DIY website - stop arguing, stop acting like you know it all. Leave a comment if you have tried this recipe and tell of your personal experience with it - leave ALL of the petty bs arguments and your personal opinions of other people out of it. **This is a very good recipe for doing some basic ornamental designs, and an awesome medium for children. You can bake it @200° for an hour or so, but air-drying is better. Paint when completely dry and use a clear coat to seal.

JohnB123 (author)2015-10-07

Simply, its an Ogoo variation ...

cmartin19 (author)2015-10-07

The Shaup family, invented Sculpey in 1967.

steve.fenster.5 (author)2015-10-07

You have not done your homework. The MSDS sheet clearly states that the product IS PCV. The adulterants you claim, like lead, is purely false. HCl gas may be emitted when baked however. You get an F.

delicia.ambrosino.1 (author)2015-10-07

This has nothing to do with who saw who or what is in what. This is about the above recipe. I have used this recipe countless time over so many years it makes me want to cry thinking about it. As good as this stuff is for making ornaments and other simple items it is by far and away nothing like Sculpey which can be manipulated forever and can be highly detailed in full dimension. The salt/soda dough makes great snowman, gift labels, cut outs for holidays, and other simple decorative items. It does have tiny pores in it and can feel sort of rough to the touch where Sculpey has neither of these. The S/S recipe items should be primed before painting for the above same reasons. I wish there could be a homemade clay like Sculpey. You had my heart racing there for a Nonetheless the S?S recipe IS a good clay recipe for simple items and more people should actually give it a shot.

webtarkeena (author)2015-10-06

I did this last year or maybe the one before at Christmas to make basic flat ornaments - similar to the way you might use salt dough. In comparison to salt dough this is Much prettier when set, and while I did not try hard to break it, it is certainly no More fragile. Compared to actual Sculpey, I wouldn't want to bet though. I also didn't really try to sculpt anything, just roll and stamp with a cookie cutter and then a rubber stamp. I also didn't try to dye or paint it.

loubee2 (author)2015-10-06

I'm sure this is great, fun, inexpensive clay for kids & some adults, but it wouldn't be a suitable Sculpey substitute for a serious adult craftperson/artist.

Igioteno (author)loubee22015-10-06

Yes that is true. This is just a substitute.

IamTheMomo (author)2015-10-06

Please give the time and temperature for baking?

Igioteno (author)IamTheMomo2015-10-06

The time is 10 minutes depending on the thickness of the clay model. Thetemperatire is 350 degrees.

jimrittenour (author)2015-10-06

You don't bake it. Mix it while using the burner (not burning hot) . Stop when it looks and feels like mashed potatoes.

Waste your time?

Your wasting your time commenting on projects you have intentions of experimenting with; and ours.

jeanniel1 (author)2015-10-06

According to Sculpey: Bake at 275 °F (130 °C) for 15 minutes per 1/4 in (6 mm) thickness. DO NOT MICROWAVE. Baking should be completed by an adult. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDEDBAKING TIME.
