STARTSO WORLD Silicone Mold Making Kit 80OZ Jade Green - Fast Cure

In this review the STARTSO WORLD Silicone Mold Making Kit stands out as a practical choice for crafters who need a reliable, food-safe silicone that mixes easily and cures quickly. The biggest reason to buy is its combination of platinum-cured durability and a simple 1:1 volume mixing ratio, which makes it approachable for beginners while still delivering reusable molds that withstand repeated use. It is particularly useful for small to medium casting projects where a low-viscosity, bubble-resistant pour speeds up workflow without specialized equipment.

Key Features

• Platinum-cured material: Durable silicone designed to be stretched and used repeatedly, offering longevity for many casting cycles.
• Easy 1:1 mixing: A true single-ratio system that reduces measurement errors and simplifies preparation for first-time users.
• Fast curing at room temperature: Initial cure and demolding in 4-6 hours at 23C/73.4F allows faster project turnover than many slow silicones.
• Low viscosity and self-deaeration: Smooth pours with minimal air entrapment mean fewer bubbles and cleaner mold surfaces without vacuum equipment.
• Food-safe formulation: Suitable for edible molds like candies and chocolates, expanding use to kitchen confectionery and ice molds.
• Wide casting compatibility: Works with resin, plaster, wax, soap, cement and other common casting materials for varied craft projects.

Who It's For

The kit is aimed at hobbyists, small studio crafters, and home bakers who want a reliable, food-grade silicone that is easy to measure and mix. Its low viscosity and bubble-free behavior make it a good fit for makers without access to vacuum degassing equipment, and the relatively fast demold time speeds up iterative work on prototypes or small batches.

Those working on very large molds, industrial production runs, or projects that demand ultra-long working time should look elsewhere; bigger or slower-curing systems with extended pot life or specialized additives may be a better match for high-volume manufacturing.

Pros & Cons

Pros

• Simple 1:1 mixing ratio reduces setup mistakes for beginners and pros alike.
• Fast initial cure and demolding at room temperature shortens project timeframes.
• Low viscosity and self-deaeration reduce bubbles and produce cleaner molds without extra gear.
• Food-safe formula expands uses to edible molds like chocolates and ice cubes.

Cons

• Some users report tackiness after 24 hours, so post-cure handling may require attention for certain uses.
• Quantity versus price has mixed feedback, so larger-volume users may find cost per mold higher than bulk industrial silicones.

Frequently Asked Questions

Is this silicone food safe?
Yes, the formulation is described as food safe and suitable for candies, chocolates, cakes and ice molds when properly cured.

How long before I can demold?
Initial demolding is possible in 4-6 hours at room temperature (23C/73.4F), with a full cure around 12 hours depending on thickness.

Do I need a vacuum chamber to avoid bubbles?
No, the low viscosity and self-deaeration properties reduce bubbles and generally eliminate the need for vacuum degassing for most small to medium pours.
