Sculpey UltraLight Mixing With Other Types Of 
Polymer Clay And The Water Test

"New Sculpey UltraLight clay is soft and light yet bakes hard in your oven. Great for paper crafts, ornaments, armatures 
and even floats! It can be colored by mixing it with Sculpey III, Premo or any other brands of polymer clay."

For years I've been making aquatic toys and experimenting the use of polymer clay in water, examples, Snow 
Globes, Aquafloats, Marine creatures and many others. My earlier experiments uses styrofoam, sponge, cork, straw, 
wood,and anything that makes the polymer clay floats. As some of the polymer clay are porous, it absorbed water 
and my flotation started to sink after a few days.
Its a great jubilation, Sculpey UltraLight will FLOATS, below are my experiment and test, mixing UltraLight with
other brands of polymer clay.

Sculpey UltraLight mixing it with other clay test


Unbake UltraLight polymer clay shape into a ball and a flat piece of 
clay disc



Testing the unbake UltraLight clay shapes in the water and floats



Unbake UltraLight, Bake & Bend polymer clay shaped into balls, mixing 
with 50% UltraLight and 50% B&B to form ball and flat clay disc for the test



Testing the unbake Bake & Bend clay shapes in the water and he clays 
sank to the bottom



Unbake UltraLight, Sculpey III polymer clay shaped into balls, mixing with 
50% UltraLight and 50% SculpeyIII to form ball and flat clay disc for the test



Testing the unbake Sculpey III clay shapes in the water and floats



Unbake UltraLight, Premo polymer clay shaped into balls, mixing with 
50% UltraLight and 50% Premo to form ball and flat clay disc for the test



Testing the unbake Premo clay shapes in the water and the clays sank to
the bottom



Unbake UltraLight, Fimo Soft polymer clay shaped into balls, mixing with 
50% UltraLight and 50% FS to form ball and flat clay disc for the test



Testing the unbake Fimo Soft clay shapes in the water and floats



Unbake UltraLight, Fimo Classic polymer clay shaped into balls, mixing 
with 50% UltraLight and 50% FC to form ball and flat clay disc for the test



Testing the unbake Fimo Classicclay shapes in the water and he clays 
sank to the bottom



Unbake UltraLight, Cernit polymer clay shaped into balls, mixing with 
50% UltraLight and 50% Cernit to form ball and flat clay disc for the test



Testing the unbake Cernit clay shapes in the water and the clays sank to 
the bottom



Unbake UltraLight, Dukit polymer clay shaped into balls, mixing with 
50% UltraLight and 50% Dukit to form ball and flat clay disc for the test



Testing the unbake Dukit clay shapes in the water and floats



Baked clays at 130º C for 25 minutes



First test Sculpey UltraLight and floats



Test two, Sculpey UltraLight, Sculpey III, Premo, Bake & Bend and floats



Test three, Sculpey UltraLight, both shapes for Fimo Soft floats but.
the ball shape for Fimo Classic sank to the bottom



Aquatic test create a miniature frog with Fimo Soft mixture and it floats



Test five, all types of polymer clay test and most of them floats with the 
exception of the baked Fimo Classic ball mixture it sank immediately



After 10 days, notice that there are 2 types of clay that sank to the bottom, 
both Fimo Classic shapes, Bake & Bend Ball. The results is due to density 
of the clay, the FC ball sank immediately, then porosity set in for the flat FC 
clay disc, about 10 days later it also sank to the bottom. As for the Bake &
Bend clay ball, it sank after 10 days due to porosity, water absorbed into 
the clay.



The 20 days test the water in the container evaporates, the rest of the 
polymer clays and my froggy still floats, with exception of Fimo Classic 
mixtures, Bake & Bend mixtures.


CONCLUSION

In general, most of the clay will floats if you mixed 60 % UltraLight plus 40 % of 
any brand of polymer clay. UltraLight  is an interesting polymer clay, the softness, 
lightweight and white matt surfaces, allows you to draw with permanent marker and 
paint with acrylic paints. Mixing with all kind of polymer clay to create shade of colors 
and its quality is much better than Original Sculpey Clay. It is a very good polymer 
clay medium to expand your creative clay project, print your hand print, perhaps 
even to create flying model plane beside any aquatic projects.
