Getting Started:Polymer clay may stain. CLAY MAY DAMAGE UNPROTECTED FURNITURE OR FINISHED SURFACES. DO NOT USE polymer clay on unprotected surfaces. We recommend working on the Sculpey® Work ‘n Bake Clay Mat, wax paper, metal baking sheet, or disposable foil. Start with clean hands and work surface area. Bake on oven-proof glass at 275°F (130 °C) for 30 minutes per ¼" (6 mm) thickness. For best baking results, use an oven thermometer. DO NOT USE MICROWAVE OVEN. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDED BAKING TIME. Wash hands after use. Baking should be completed by an adult. Begin by preheating oven to 275 °F (130 °C). Test temperature with oven thermometer for perfectly cured clay.
The consistency of liquid Sculpey can change over time becoming thicker with age. Thicker liquid Sculpey will be preferred for this project so that it holds its shape better and doesn’t spread out distorting the shape of the letters. Test your liquid Sculpey before using on your lettering project. Squirt a letter out on a baking surface and see how long it takes for it to level or spread on it’s own. If the test holds it’s shape for several minutes, this would be desirable for the project.
Decide what message you would like to make and what font you would like to use. For my message, I chose the words, “Hello Beautiful” which will be displayed on a bathroom mirror. I chose a font from my computer that is a script because the letters are hooked together making it easier to apply to the mirror. I also chose the script lettering because it is thick enough for me to follow with the liquid - a thinner script might be more difficult to trace and show mistakes more clearly.
If choosing a very large or long word, you can print the letters out on separate sheets of paper, trim them out, and then tape them back together closely as shown in the word, “Welcome”.
Place the printed words under a smooth piece of glass that does not have any insignias, scratches, or texture. The glass I am using is textured on the bottom, but the top side where I will apply the liquid is completely smooth. In the video and the photo, I have already completed the word “Hello” and baked it. If your words will be applied to the mirror separately, it doesn’t matter how they are arranged on your glass work surface.
Squeeze excess air from the liquid bottle. Start on a thick area of your first letter. Outline the letter with a thin line on both the outside and the inside edges.
Fill in the thick parts of the letter neatly with more liquid. Because liquid Sculpey has mica in it which leaves little trails which show up more when it’s baked, it’s important that you fill in the letters very neatly.
Continue tracing and filling in all the letters of the word. Bake the word at 275 for 30 minutes.
Allow the lettering to cool completely and then carefully remove by peeling with your fingernails or scraping off the glass with a craft spatula. Be careful not to slice into your letters while removing.
When liquid Sculpey is baked on a smooth non porous surface, it takes on a very flat smooth back. That is why it is excellent for creating a cling that will stick to another smooth non porous surface.
You can use the knife blade in the 5 in 1 tool to clean up or trim any little areas that might not be perfect from the baked liquid Sculpey.
Place the message on a mirror or window as you desire. Make sure all the letters come into contact with the glass. You can remove and reposition the letters as necessary. As long as they are clean on the back and the glass is clean they will make good contact and stay as long as you wish.
