STARTSO WORLD Silicone Mold Making Kit 80OZ Platinum Silicone - Fast

In this review of the STARTSO WORLD Silicone Mold Making Kit the bottom line is simple: this kit is best for hobbyists and small-scale makers who want a fast-curing, food-safe silicone that is easy to mix and yields durable molds. The reviewer found the 1:1 by volume mixing ratio and low viscosity made setup quick and forgiving, while the platinum-cured formula produced molds that can be stretched and reused many times. Occasional tackiness after curing and mixed opinions about value are noted, but the kit shines for ease of use and predictable results.

Key Features

• Platinum-cured material: Provides a durable, long-lasting silicone mold that can be stretched and used hundreds of times for repeated casts.
• 1:1 mixing ratio: Simple by-volume mixing reduces measurement errors and makes the kit approachable for beginners.
• Fast room-temperature cure: Initial demolding in 4-6 hours at 23C/73.4F lets you iterate quickly, with full cure around 12 hours depending on thickness.
• Low viscosity and self-deaeration: The pourable, low-viscosity formula flows into details and minimizes entrapped bubbles without a vacuum chamber.
• Food safe formulation: Safe for making molds for candies, chocolates, cakes and ice cubes when properly cured.
• Wide casting compatibility: Works with epoxy, plaster, wax, soap, cement and concrete for a variety of craft projects.

Who It's For

The kit suits beginners and intermediate crafters who value straightforward mixing and quick turnaround; the 1:1 ratio and low viscosity are forgiving for new users attempting resin, soap or candy molds. Small studios and DIYers who need a reusable, food-safe silicone for occasional production runs will also appreciate the durability.

Those who should look elsewhere include large-volume commercial molders who require industrial-scale quantities or faster high-temperature cure systems, and users sensitive to occasional tackiness may prefer a different grade or added post-cure step to eliminate stickiness reported by some customers.

Pros & Cons

Pros

• Easy 1:1 by-volume mixing makes setup quick and accessible to beginners.
• Fast initial cure (4-6 hours) allows rapid demolding and faster project cycles.
• Low viscosity and bubble-free pour reduce the need for vacuum equipment.
• Platinum-cured, food-safe material yields durable molds suitable for edible casting.

Cons

• Some users report tackiness after 24 hours, so delicate finishing or a short post-cure may be necessary.
• Per-volume quantity may feel expensive for larger projects compared with bulk industrial options.

Frequently Asked Questions

Is this silicone safe for food molds?
Yes, the product is described as food safe when fully cured, making it suitable for candies, chocolates, cakes and ice cubes.

How easy is it to mix and pour?
The silicone uses a 1:1 by-volume ratio and has low viscosity, which makes mixing and pouring straightforward and forgiving for beginners.

Will I need a vacuum chamber to avoid bubbles?
In most cases no; the low viscosity and self-deaeration properties reduce bubble formation, though fine details may still benefit from careful pour technique.
