Foil Pan Lids Will Protect Your Polymer Clay In The Oven

Foil Pan Baking Tips - Polymer Clay TutorVideo #595: Watch this to see what can happen to polymer clay pieces that are not properly protected during the baking process.

Topics Covered In This Video:

  • How to use a foil pan lid to prevent burning your polymer clay when baking.
  • I show two samples of small pink hearts cut from Premo polymer clay and baked for 1 hour at 275F.
  • One heart was baked directly on the metal pan with no cover.
  • One heart was baked on 4 layers of cardstock with a foil pan lid.
  • The one on the pan without the lid got fried to a crisp, and the other was just fine.
  • I have seen people on YouTube baking their pieces on a metal pan all the time.
  • This means that their pieces are constantly burning… or more likely, that they are baking for far less time than is required to prevent their pieces from becoming brittle.
  • I found a BBQ Roasting pan that fit my metal pan perfectly.
  • Line your pan with several layers of manila file folders cut to size.
  • I like the heavy weight of the enameled metal pan because it holds the heat and keeps the temperature more even and constant.
  • Tinfoil pans used as a base don’t hold the heat like a heavier metal pan will.

    I bought some foil pans after you had a video about them for covering and use them when I have bigger pieces that won’t fit into my little oven. I’ve never baked on metal but I have baked on tile with no lid and had no burning or scorching. That’s just when I’m in a hurry and forget to cover them.

    I have my toaster oven set up in the bathroom so the fumes can be vented outdoors. I want to use my home oven, but I’m afraid that even with the aluminum covers, the smell will completely overwhelm the house and me… So when you use your kitchen oven and cover with aluminum pans, does it do a great job of concealing the fumes and can you still use your kitchen oven for food after using it for polymer clay?

  3. Bertha A., 21 November, 2014

    I have baked in my kitchen oven with aluminum pans as a a cover a few times. I have a modest townhouse and fumes can travel to other rooms quickly. And I am quickly bothered by strong fumes. I have not had any problems with baking clay in my kitchen oven. I do pick up some faint fumes when I open the oven, but as I said I tend to notice these things more than many people. And they dissipate pretty quickly. I do run the fan above the stove/oven.

    I think they might be a little strong if I was baking a large amount of clay for a very long time (e.g. several batches) but if I crack the patio door (even in cold weather), the brief infusion of fresh air should get rid of it. Seriously, the smell is stronger and lasts longer when I cook pancakes or bacon

    I don’t detect any lingering fumes in the oven and feel fine about using it for food later. Just be careful about the temperature so you don’t burn the clay. My kitchen oven actually heats up about 25-40 degrees F hotter than the dial setting. The aluminum cover won’t stop the burning if the oven is that much hotter! So I check it with a couple of thermometers before I put in the clay. I have burned clay and THAT is not nice.

    But I say try it once as Cindy describes and see how YOU feel about the smell. Your oven should be fine. I am one of those people who is suspicious about the impact of manmade chemicals on humans so I don’t take this lightly. But these clays are approved by the EU and they seem to have even stricter guidelines about toxins in crafts so I think being moderately cautious and careful should keep your oven safe. (At least as much as anything else in the average modern lifestyle!)

    Thank you for your reply. I wanted to be sure I was not going to poison my family. Eventually I will get a toaster oven for clay, but now I wanted to be sure I could use the oven.

    Cindy, I started using the aluminum pan covers a few months back when I notice you were covering your tray with it. I couldn’t find the ones with holes in the sides so I took an awl and made my own. It was such a wonderful improvement, it was quick and easy and everything I bake comes out just perfect especially the translucents. Another thing I always check is the links you have under “You might also like” at the bottom of the page. I have run across things from way back when that I had not seen before or had forgotten about and it is always nice to review them.

    Hi Dixie Ann, I don’t know if it makes that much difference to have the holes in the side… maybe it lets the warm air flow around better but maybe it doesn’t matter? The holes were in the pan that fit, so I used it. Works beautifully though!

  7. Patt W, 21 November, 2014

    I have ALWAYS covered my clay. I use aluminum foil, double folded. Been very lucky and no scorched or burned beads. Covering is definitely the answer to have pretty work. The pan covers are in the works, for a glass vase I want to cover. It is too tall the the convection oven. Your tips and techniques are always soooooooooo welcome.!!!!!!!!!!!! TY TY TY …………

  8. Sarah G, 21 November, 2014

    I have a question, as I am not baking clay yet.

    Is it safe food wise to use my wall oven? I saw online if I use two aluminum pans that it traps everything inside. However I see Cindy uses a pan with holes. I am wondering how safe is it to bake clay in an oven that is used for food as well?

    I am so confused, as I have read on blogs to never do this, and then on another blog I read that its safe to bake clay in the oven.


  9. Cindy Lietz, 01 December, 2014

    Hi Sarah, polymer clay (at least the brands that are sold in North America) are certified non-toxic and safe to use in home ovens. If you burn your clay there may be a smoky residue on the inside of your oven that you will need to clean before using your oven for food so that you don’t impart the taste of the burnt clay to your food. If you have more concerns, you should go to the manufacturers sites.

    I was watching one of you Videos for Beginners and you were showing covering your clay while Baking and you used Foil Pans and one, but not the other of them had Holes in it along the side. Being a real Beginner I’d like to know why, and should I always Punch holes along the side or not? Thank you for taking the time to answer my question. I have watched a lot of your Videos and have found them very informative, but I couldn’t find an answer to this question, Again, Thank You for all you help.

  11. Cindy Lietz, 02 June, 2017

    Hi Elizabeth, the reason those holes are in there is because they were already there when I bought the pan. :) I was looking through the aisle and found a pan that fit perfectly over my baking pan that came with the oven. The foil pans I found happened to be meant for using in the BBQ and had the holes there already. Now whether they make a difference or not, that I don’t know for sure, but they definitely don’t harm it. In fact they probably help with the flow of warm air. If your pans don’t have the holes, you can punch them in if you want. I have baked lots of pieces with a closed lid and achieved good results, so if you don’t want to punch the holes, you don’t have to. So does that help mud the waters a little? ;)

  12. Elizabeth Phillips, 02 June, 2017

    I wrote you a prior question and forgot to ask my other questions, so if you want you can answer them both in the same e-mail. This question is how small can Polymer Clay Beads can be need for example sizes like 8/0 11/0 or do they gave to be big, as most of the people’s Videos I have seen show beads a quite large and to be honest rather Gaudy for my taste. FYI: I am almost 57 or will be on June 20th, 2017 and am a no BS Shoot from the Hip, and Speak my mind kind of person, that is to say I don’t lie but I try not to be unkind. So, when I say that I have found your Videos the best out of all the tutors that I have watched, I am not a Bum Kisser it is just my personal opinion and not intended to insult those who know a lot more about working with Polymer Clay then I do, it is just I find yours more informative and even though I’m a Beginner (Have not actually made anything yet, as I just got out of the Hospital) I like that you don’t talk down to those who know less then you and to be honest I don’t really know much of anything when it comes to Polymer Clay that doesn’t mean I’m a Idiot I have a B.S in Sociology and Psychology and graduated Cum-Laude, so being talked to like I have the language comprehension of a 4th Grader is insulting.

    I also wanted to ask if it is safe to use my Regular Oven to Bake Polymer Clay and if so what do I have to do before using it for food, I do know that Baking Polymer Clay with Food would be very Dumb as Polymer Clay has Chemicals in it that shouldn’t be eaten.
    Again, Thank You (and your Husband) for taking the time to answer my questions

  13. Cindy Lietz, 02 June, 2017

    Hi again Elizabeth (I answered your previous question above.) I love that you are a shoot from the hip, no BS kind of gal and that you aren’t a bum kisser as you say! Me too, that’s why we will get along quite nicely! :)

    As far as making tiny little seedbead size beads out of polymer clay, that is entirely possible, but not very easy. That is why you see the bigger beads. It’s not so much making them tiny, but the finishing that is difficult when they are that small. Sanding, polishing and glazing is all pretty tricky to do on super tiny beads. Plus you can’t really do anything cool on them in regards to patterns or surface effects. That being said, you don’t have to make gaudy ones if you don’t want to. You can make them in any style, color or size you want. That is the beauty of using a material like polymer clay.

    In regards to baking in your regular oven, you can definitely do that too. I would use the foil pan lid to help keep the polymer residue from coating the inside of your oven and I wouldn’t bake food and clay at the same time, but it is rated non-toxic and safe to use in your oven, so don’t worry about that.

    No buy some clay and get started! No more research until you’ve played a little with the clay. You don’t need all the cool tools and all the right info, to get started. Just start and see what happens. Then come back and get the info you need. I have courses and tutorials you can buy and tons of free info here, once you see what it is that you don’t know or would like to learn. But the key here is to just do. It doesn’t matter if the first stuff you make is a total disaster. It is more important to get started and get better from there. :)
