Artriso vs Jesmonite: An Honest Comparison from the Manufacturer

I run Artriso, the Hyderabad studio that makes CALSO ONE. So this Artriso vs Jesmonite comparison is written by a competitor of Jesmonite. You should read it with that in mind.

What I can promise is that the comparison is honest. Jesmonite is the global reference standard in water-based casting resin and genuinely well-engineered material. CALSO ONE is the more accessible, more affordable, single-component Indian alternative in the same category. The right question is not which is better in the abstract. It is which one fits the studio you are running today.

The short answer

If brand recognition matters to your customer base, or you have already invested in a Jesmonite-trained workflow that is working, stay with Jesmonite. It is the premium reference for a reason.

If you are looking for a more affordable option in the same category, a simpler single-component workflow that is easier to teach and learn, or a domestically-made Indian brand with direct manufacturer support, CALSO ONE is built for you.

Below is the factor-by-factor breakdown.

Quick comparison: CALSO ONE vs Jesmonite AC100

What you are actually comparing

CALSO ONE is a single-component, water-based, mineral-loaded acrylic casting powder. You add water in a 3:1 ratio by weight. That is the whole kit.

Jesmonite AC100 is a two-component, water-based, mineral-loaded acrylic casting system. You combine the base powder with a proprietary acrylic liquid in a 2.5:1 ratio by weight.

Both belong to the same material category. Both cure by chemical reaction, not by drying. Both produce a hard, matte, mineral-finish piece that takes pigment cleanly and can be sanded, sealed, and polished. If you want the full primer on the category itself, the complete eco resin guide covers it.

This comparison is about the differences inside that shared category.

Factor 1: Workflow

Single-component versus two-component is the biggest workflow difference between the two products.

With CALSO ONE you measure powder, add water, mix, pour. One step. The 3:1 ratio is the only variable you need to get right.

With Jesmonite you measure powder, measure liquid, combine, mix, pour. Two measurements. The liquid component has its own weight, its own opened-bottle shelf life, and its own ratio sensitivity.

Neither workflow is hard once you have a few pours behind you. Single-component is simply a shorter learning curve for first-time pourers and teaching studios, because there is less to get wrong on the way to a finished cast.

Factor 2: Price in India

Both products are now available domestically in India. Jesmonite is sold through its official Indian channel at approximately ₹900 per kilogram. CALSO ONE is sold direct from our Hyderabad warehouse at the per-kilogram prices below, which step down with pack size.

At the 1 kg trial pack, CALSO ONE Off White is roughly 55 percent of the Jesmonite per-kilo price. At the 15 kg studio pack, the same shade is closer to 46 percent. Brilliant White, our higher-purity option, still sits below Jesmonite at every pack size, though the gap is narrower.

For a working studio casting 8 to 10 kilograms a month, the annual saving on resin alone ranges from ₹40,000 to ₹50,000 depending on shade choice. That is a real difference in operating cost. Whether it matters more than brand recognition is the strategic call you have to make for your own business.

Factor 3: Supply and distribution

Both products are domestically available. The shape of the supply chain differs.

CALSO ONE ships direct from our Hyderabad warehouse. The manufacturing line, the warehouse, and the customer support inbox are all one team. When you email contact@artriso.com about a question, the same people who made the product answer the email.

Jesmonite is supported through its official Indian distribution channel. Restock cycles and customer support flow through that channel. The loop works, but the contact point is the distributor rather than the original UK manufacturer.

Neither setup is structurally better. They are different. Direct-from-manufacturer suits buyers who want a fast feedback loop on questions or custom requests. Distributor-supported suits buyers who already have an established relationship with the official Jesmonite channel in their region.

Factor 4: Finish and feel

This is the factor where the two products are most similar.

Once sanded and sealed, a CALSO ONE cast and a Jesmonite AC100 cast read close to identical to most customers. The hand-feel is the same mineral matte. The pigment behaviour is the same. Piece weights are within a few percent of each other for the same mould.

The differences are subtle and visible mainly to experienced makers.

CALSO ONE Off White reads slightly warmer than Jesmonite AC100 white out of the bag, which is intentional because most Indian buyers prefer a warmer neutral. If you want a closer match to AC100 white, Brilliant White from the CALSO ONE collection is the cooler base.

These are bench differences. They are not differences a customer notices in a finished piece on the shelf.

Factor 5: Pot life and demould

Both products give you a similar working window. The numbers below are at typical Indian indoor temperatures of 24 to 30 degrees Celsius.

CALSO ONE: pot life 12 to 15 minutes, demould 45 to 60 minutes for thin casts, 60 to 90 minutes for mid-size, 2 to 3 hours for thick or sculptural pieces. Full cure 24 hours.

Jesmonite AC100: pot life 15 to 20 minutes, demould 45 to 90 minutes for thin to mid-size, longer for thicker pours. Full cure 24 to 48 hours.

Jesmonite gives you slightly more pot life, which can be useful for complex marbling or working alone on multi-mould pours. Both are workable for most studio production.

Factor 6: Brand and customer expectation

This factor matters more than it looks, and it tilts toward Jesmonite.

Jesmonite is the recognised global brand in this category. Some Indian interior designers, gifting accounts, and B2B buyers ask for it by name. A studio that has built a customer base around the Jesmonite brand has something real to protect, and switching to any alternative carries a marketing cost that has nothing to do with the chemistry.

CALSO ONE does not match Jesmonite's brand position in India today. We are an Indian-made challenger in a category Jesmonite created. That gap is closing as the local studio community grows, but pretending the gap does not exist would be silly.

If your business model leans on selling the Jesmonite name, stay with Jesmonite. If it leans on a finished aesthetic that customers value regardless of the underlying brand, CALSO ONE is a serious option to evaluate on its own merits.

So who is each product for?

Pick Jesmonite if you have a Jesmonite-trained customer base, you already run a tuned two-component workflow that delivers consistent results, the per-kilo price is acceptable for your unit economics, or you specifically want the global reference brand on your studio's material card.

Pick CALSO ONE if you are looking for a more affordable option in the same category, you prefer a simpler single-component workflow, you are running a teaching studio where a shorter learning curve matters, or you want a direct line to an Indian founder-led manufacturer for support and feedback.

For comparison with the other locally-made Indian eco resin in market, we have compared CALSO ONE to Beyond Mix in a separate spoke post.

How to test for yourself

The honest way to settle a material comparison is to pour both side-by-side on your own moulds, with your own pigments, on your own workbench.

Order a 1 kg trial pack of CALSO ONE Off White at ₹499. Pour your standard production piece. Compare to your last Jesmonite pour from the same mould. Judge the surface, the pigment behaviour, the demould feel, and the finished weight on your own scale.

If CALSO ONE works for you, the math at studio pack sizes is favourable. If Jesmonite still does the job better for your specific product line, that is also a fine answer. The point of this comparison page is not to convince you of a switch. It is to give you the information to decide on the merits.

Frequently asked questions

Is Artriso the same as Jesmonite?

No. Artriso is the company name. CALSO ONE is our flagship eco resin product. Jesmonite is a separate UK-based company with its own product range. Artriso and Jesmonite are competitors in the same material category. CALSO ONE is a single-component water-based eco resin made in Hyderabad. Jesmonite AC100 is a two-component water-based eco resin sold in India through its official channel. The finished pieces look similar once cured and finished. The workflows, prices, and brand positioning differ.

How much cheaper is CALSO ONE than Jesmonite in India?

Jesmonite retails at approximately ₹900 per kilogram in India. CALSO ONE prices range from ₹413 to ₹699 per kilogram depending on pack size and shade. At the 1 kg pack, CALSO ONE Off White is around 55 percent of the Jesmonite per-kilo price. At the 15 kg pack, the same shade is closer to 46 percent. Brilliant White is somewhat closer to Jesmonite on price but still below it at every pack size.

Will Jesmonite tutorials work with CALSO ONE?

Mostly yes, with one calibration step. Jesmonite tutorials cover technique (pouring, marbling, pigmenting, sealing) that transfers directly to CALSO ONE. The thing you need to recalibrate is the mixing ratio: CALSO ONE is 3:1 powder to water by weight (single component), Jesmonite is 2.5:1 powder to liquid by weight (two component). Every other step of the technique applies.

Can I switch mid-project from Jesmonite to CALSO ONE?

For sequential pieces in a series, yes. The colour and surface read close enough that a switch between batches is rarely visible in a finished collection. For a single piece that has been started in one material, do not switch mid-pour. The two products do not chemically bond if you try to layer one on top of the other mid-cure.

What if I want to keep using Jesmonite for some pieces and CALSO ONE for others?

Many studios run both. Use CALSO ONE for high-volume production work where margin matters, and reserve Jesmonite for the small number of pieces where customer expectation is set around the brand. The two products are not exclusive. A studio can stock both, on the same shelf, for different products in the catalogue.
