All hand made.
These are all just plain colors in day light. My reef fixture really brings out the colors.
I am going with the idea that it's safe.
Just non toxic pvc plastic once cooked.

I will be the test gunipig.

Can you post how you made them? Just melted PVC? What dye did you use?

Just regular sculpey, and layer the colors. Then carve, pack in salt. Roll out with a golf ball. Then cook. I can post some details any one is interested. Kind of a cross between painting with thick oil paints, and working clay. Salt, powdered sugar help hold the carved shape as it adds micro texture.

I read a blog a while back about making synthetic reef rocks, out of it. From a salt water guy.

Spent 2 hours ready about clay, wow so many types. Well I need the premo, or souffie type of sculpey, as the stuff I got is the cheap and weak variety.
Guess I will find out when the cichlid attack.

Some of that stuff isn't food safe. I made a cool "tobacco" pipe (wink wink) and then found out you couldn't smoke out of it.

Too cold outside, off work for the week. So kitchen engineering. I have been playing with putty.
The sculpy 111, cooks at 275. Well that allow it to bond in a pressure cooker, at 15 psi. Which I ran some tests.20171227_090458.jpgAfter 2 hours of hard boiling, the water is clear. The pieces is solid, but will delaminate where colors are pressed together. This is the lower strength sculpey 111.

Most remarkable it that sculpey 111 will cure under water in a pressure cooker.

Pvc pipe meet pvc polymer at 260F at 15 psi. It bonds COMPLETELY. About as good as epoxy. It can be sanded, carved.

The red dotted piece is a pic coupler. It shrank slightly, in the pressure cooker, and cracked at the joint. The polymer putty, does not adhere to its self if cured and re heated.
I fixed it with a hot glue gun.

Freezer paper, fin foil, and plastic canvas.20171227_061139.jpg
Cover plastc canvas with base color. Flip over and place on tin foil. It will stick to the foil until cooked.
Add clay in layers, like paint, then blend the layers.20171227_062941.jpg
I used some ugly colors, as I was experimenting.20171227_064900.jpg
Pack salt in putty for some fine porous looking details 15143989023781379836444.jpg I have 425nm 440nm and 465nm acentic, UV, and Indigo. In my led fixture.

The plastic canvas baked into the core of the sculpey 111. Makes them alot less brittle. Cooking them at 275 for 15 min. Gells the plastic canvas and will curve if objects are used to contour the surface.
