Make round resin spheres in different sizes easily with the clear, two-part silicone mold.  Great for creating unique resin paperweights and trinkets.

The clear silicone allows you to see what you are doing while you are resin casting.  Being able to see through the mold means fewer mistakes as you can exactly see where to place any additions or extra embedments.  The two-part mold has a hole at the top to allow you to use casting resin.

Choose from nine different size diameters:  20 mm, 50 mm, 100 mm.

Using this mold to make resin spheres and balls is as easy as:

1.  Mixing and pouring resin into the opening at the top.

2. Set aside to cure

3.  Once dry, flexing the silicone around the casting to release the resin.

Pro tip:  To keep create a tight seal on the seam of the two parts, seal with a hot glue gun.  Remove the glue after the resin is cured, then peel the resin away from the mold.

Because the molds are small you may want to warm them slightly with a heat gun before use.  For the optimum life of your mold, use resin mold release to make sure your castings come out perfectly.  

The sample resin ball shown is not included with purchase.

One for every size!

It's near impossible to find half spheres (or whole spheres, for that matter) in sizes larger than two inches. That's where Resin Obsession comes in with every handy dandy size! The thick silicone feels fantastic to work with.

I only wish the base on the 100mm were wider, because I've already jiggled the table and spilled one... oops... The base is indeed very narrow haha.

Not dire

I just worked with this one’s so im not the best source but I had a hard time for closing the sphere and then the final product has a line in the middle that I wasn’t expecting I’ll try again eventually but not happy

Hi Elizabeth, I'm sorry to hear this mold is making it challenging for you to get a perfect casting. I find I have the best results using this two-part mold when I use a glue gun to glue the two parts closed before pouring the resin. Once your resin cures, peel the glue off the outside, then demold. I've had the best luck avoiding a line that way. Let me know if that works for you too.
