The Silicone Cure

Mold making is super fun. Almost any random object in your house can be cloned! Your creativity can be unleashed with this medium that once cured can be used with resin, plaster, and Jesmonite!

Marvelous Mold Making Silicone is a 2-part platinum based silicone. It cures flexible and shows amazing detail of your object.

Here are a couple of  trouble shooting tips if you're a newbie...
1- Cure Inhibition

Your master object may inhibit the curing of platinum silicone where they were in contact.
Materials that may inhibit the curing process are:

Sulphur may be present in for example latex, natural rubber, neoprene, PVC, wood, oils and some solvents.  Your master (sculpture) or gloves may contain sulphur.

Applying latex, urethane or silicone rubber directly over clay containing sulphur will result in your silicone not curing as well.

Other ingredients that may inhibit the curing process:

Tin: may be present some adhesives and also present in some types of PVC plastic.

Some metals: such as silver, lead and mercury.

2- Leaking

Your master object must be properly encased. 
This may be a plastic container, a tape-lined cardboard box or a custom created acrylic housing. Our silicone has extremely thin viscosity - like water. If your housing isn't completely sealed around the edges, the silicone will just leak right out. 
If using a casing that does not have a bottom already attached - make sure the outer edges are completely sealed to the bottom with hot glue.

Happy crafting!

Thanks for writing such an informative blog which will surely be a great help for the readers.

I’m interested in reading your article, and your content is on point. Well done to the team.

We recently published an article that discusses silicone rubber products on a similar topic.

Either way, keep up the awesome work!
