Freshware SP-100RD 6-Cavity Rectangle Premium Silicone Soap Bar and Resin Mold, Red Review (2026)

Updated September 14, 2026 · Research-based review

Our verdict

This Freshware SP-100RD mold offers 6 rectangular cavities in food grade silicone, each about 3 by 2 by 1 inch and 3 oz, rated for FDA and LFGB standards and up to 3,000 reuses. It makes clean, uniform bars, and the trade-off is the red silicone can make judging pale soap colors a little harder.

Trade-offs

  • - Only one mold in the pack, so large sessions need more

Who this soap mold fits

A dedicated bar mold with individual cavities is the most common way home and small batch soap makers pour uniform bars without cutting a loaf, and this Freshware SP-100RD gives six rectangular cavities in one flexible silicone tray. Freshware is a bakeware brand better known for baking pans and molds, which is reflected in this mold being marketed for both soap bars and resin casting rather than as a soap-specific specialty product. It suits a maker who wants a reliable, mid-size batch of six bars at a time, whether for personal use, gifting or a small market run, more than someone needing dozens of bars from a single pour. The dual soap and resin marketing also appeals to crafters who work across more than one medium and want one mold that serves both.

What the dimensions and material mean

The mold measures 8 by 7.1 by 1 inch overall, with each of the six cavities sized at roughly 3 by 2 by 1 inch and holding about 3 oz, for a total capacity of 18 oz across the full tray, useful figures for scaling a recipe to fill the mold evenly. It is made from what Freshware describes as 100 percent pure, food grade silicone meeting US FDA and European LFGB safety standards, free of BPA, PVC and phthalates, which matters for a mold handling caustic raw soap batter during the curing process. The silicone is rated for temperatures from negative 40 to positive 446 degrees Fahrenheit, far beyond what soap making requires, and Freshware states it is reusable for up to 3,000 uses, a sign of durability for a mold that will see repeated pours over its lifetime.

Living with it batch after batch

Silicone's flexibility is the main convenience here, since a cured soap bar releases cleanly with a gentle push from underneath each cavity rather than needing to be pried or unmolded with tools. The mold is also microwave, oven, refrigerator, freezer and dishwasher safe according to Freshware, which gives soap makers flexibility for speeding up or slowing down the cure depending on a recipe's needs. Because there is only one mold in the pack, a maker running larger production sessions with more than six bars at a time will need to either buy a second mold or run multiple pour and unmold cycles, which adds time compared to a multi-tray setup.

How it compares with other bar soap molds

A rival two pack of similar rectangular six cavity molds effectively doubles the twelve-bar-per-session capacity for a comparable price, an advantage for makers who consistently pour more than six bars at once. A large cavity silicone mold aimed specifically at soap making, without the crossover resin branding, may appeal to buyers who want a mold marketed purely for soap rather than dual purpose use. Novelty shaped molds, like oval or egg cavities, trade the uniform rectangular bar shape here for a more distinctive look, which matters if the goal is a signature bar shape rather than a standard rectangle like this Freshware tray produces.

Verdict

This Freshware SP-100RD mold is a well specified, durable option for soap makers who want six uniform rectangular bars per pour in a food grade silicone tray backed by clear FDA and LFGB safety standards. The stated 3,000 use rating and multi-surface safety, including dishwasher use, make it easy to keep clean and usable over a long run of batches. The red silicone color is a minor but real downside for judging the true shade of pale or white soap while it is still in the mold, and the single tray limits how many bars a maker can pour in one session. Larger batch producers should consider a two pack or bigger cavity count mold instead of this single six cavity tray.

Frequently asked questions

How much soap batter do I need to fill this mold?

The mold holds about 18 oz total across six cavities, roughly 3 oz per cavity, so size your recipe to that volume to fill it evenly without overflow.

Can this mold be used for cold process soap that heats up during gel phase?

Yes, the silicone is rated from negative 40 to positive 446 degrees Fahrenheit, well beyond the heat a soap batch generates during gel phase, and it is also oven and freezer safe.

Does the red silicone affect the soap itself?

No, the color is food grade silicone and does not transfer to the soap. It mainly makes it a bit harder to visually judge pale colors while the bar is still in the mold.

Is this mold only for soap, or can it be used for other crafts?

Freshware markets this mold for both soap bars and resin casting, and its food grade, wide temperature range silicone also suits other baking or craft uses.
