Baking Beads So They Don’t End Up With Shiny Spots

Avoid Polymer Clay Shiny SpotsVideo #422: There’s a time when shiny is good… but there are also times when it looks really terrible!

Topics Covered In This Video:

  • I did a tips video several weeks ago about How to Remove Fingerprints and Shiny Spots Using Acetone, but since there were so many comments from people having problems with shiny spots, I thought I’d do a video on how to avoid them in the first place.
  • Shiny spots on the back of your polymer clay pieces, happen when you bake on shiny surfaces. Whether it is a shiny glass or ceramic tile, a metal pan or a glass pie plate. If you stick your clay piece directly on a shiny surface while baking, it will leave a shiny spot on the back.
  • I show two samples of polymer clay; One baked directly on a shiny glass tile, and one baked on a piece of paper sitting on top of the same tile. The piece that baked on the paper has a smooth matte finish. And the one baked directly on the glass surface has a mottled uneven surface with some very shiny spots. Needless to say, the one baked on the paper looks way better!
  • You can bake any polymer clay piece on a piece of paper. Just lay a sheet or two of plain office paper (no printing) or a piece of cardstock or file folder on top of your baking pan or tile, and then add your polymer clay pieces.
  • I used to use parchment paper (aka baking paper) to bake polymer clay on, but I found that some brands will wrinkle in the oven and some will leave shiny spots… so you might as well just use regular paper instead.
  • Paper is fine in the oven at the low temperatures that we bake polymer clay at. VERY IMPORTANT: Make sure the paper does not touch the elements or the inside walls of your oven… or the paper could catch fire. But other than that, paper will be OK in the oven at low temperatures.

    I have a box of parchment paper squares that I got from somewhere! They were given to me a long time ago. They are perfect for placing on my tiles to bake my pieces on. I put another one on top when I bake flat pieces and put a second tile on top of that. Perfectly baked and no shiny spots! I was wondering what I would do when I run out. Now, I know! Thanks, Cindy!

    You’re welcome Betty! Sounds like your parchment squares don’t wrinkle, which is great to hear. Thanks for commenting!

    Thanks for this tip Cindy. Yes, I’ve been getting shiny spots and yes I will be using this tip!

    Does anyone know of an acrylic sealant spray I can buy in the UK? PMYII has been recommended but the only sites offering this are in the USA and cannot ship overseas. I want to use it to seal alcohol ink as well as polyclay.
    Many thanks – Marion

    I have used Crafters Companion Spray and Shine with no noticeable side effect yet but have only just found PC and Cindy so long term use I cannot say. I used it on a PC and mica coated Woodland Friends large mould necklace.

    I will definitely use this tip! I have had that happen often and have avoided making flat shapes because of this. Anything to help cut down finishing time!

    I haven’t been making polymer clay lately because all my supplies are put away (My beading supplies took over!!) in my small apartment and the time to finish the pieces take forever! I wish I had a quicker way to polish them. I am thinking of getting a dremel (sp?) and ask my dentist every time I see them if they have an old one. lol
    My 4 yr old is VERY interested in clay so I have to make my more complicated pieces at night after bedtime. Do you have great space saving organization tips?

    Hi Cindy! Thanks for the video! I like to use index cards, which are a good size for most of what I do, and I just put them on top of my 4 in. x 4 in. tile. Or, I also like to bake things that are not flat on the bottom, on a flattened piece of batting. &:-)

    Great tips! I also had problems with parchment paper wrinkling and have switched to cardstock. I think it’s worth noting not to set your clay pieces on the paper while they are waiting to bake unless they’re going to be baked very soon. As Cindy has said in previous videos, paper leaches the plasticizers out of clay – helpful with too-soft clay, but will weaken an uncured piece!

    I wish I could like this 100 times! I was always worried about putting paper in the oven, and always annoyed at shiny spots! You have eased my mind on both points! I’m just in the middle of a marathon viewing of all your videos. Know I will be coming back lots too. Great viewing. Thanks.

    It has been so dismal getting ready for winter. But I started watching your videos and my cares washed away. How to condition, polish, and so much more. Thank you so much.

    Hi Cindy, I have been watching your videos on YouTube and love them! I am in the midst of re-branding and want to offer clay jewelry to my line. I have been having issues that I can’t seem to find the answers for. One being when I bake my clay and do the sandwich technique it has shiny spots on both sides. I do tile, printer paper, clay, printer paper, tile. For some reason when I first tried this it worked, but now I always get these random shiny spots on both sides. I’m using premo clay and bake at 275 for 45 minutes to an hour. Have you ever heard of this problem? Thanks.

  14. Cindy Lietz, 08 December, 2020

    Thank you Carol! It sounds like your paper is either shiny or becoming shiny from the oils in the clay. Maybe the clay is extra fresh and oily these days? Try experimenting with different papers and see if that works. Or you could try baking between two pizza stones instead. Then you wouldn’t need the paper because the stones have a matte finish and don’t leave shiny spots.
