Short answer: The Tefal Renew Black Ceramic Non-stick Frypan 24cm (model C4320423) is a credible induction option if you want a lightweight ceramic pan with a heat indicator and published recycled-material claims. It works on induction, gas, electric and ceramic cooktops, weighs 0.8kg in CHOICE’s 2026 listing, and has a measured 20cm base. However, Tefal’s headline durability figure is a laboratory hardness comparison rather than proof of a particular service life, and public information does not confirm an oven-safe temperature, dishwasher rating or handle material. At the $109.99 regular price, its value depends on how much you value induction compatibility, Thermo-Signal and the eco-design disclosures. Sale examples around $39.99–$43.99 make the proposition considerably stronger, but stock and pricing vary.
Is the Tefal Renew Black 24cm frypan good on induction?
It is designed for induction and should suit most everyday induction cooking, while also supporting gas, electric and ceramic cooktops. Tefal pairs a Thermo-Fusion induction base with Thermo-Signal, an indicator intended to show when the pan has reached the recommended starting temperature.
CHOICE’s public 2026 listing records a 20cm measured base diameter and a 0.5cm base thickness. Its measurements also note magnet capability across the base to 18cm, but not at the edge. That distinction matters on induction: the practical magnetic area is smaller than the advertised 24cm rim, so a large induction zone may not heat the entire cooking surface equally.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
CHOICE recorded the base as concave when heated. A slight change in shape as aluminium warms is not automatically a fault, but it can affect contact on some glass induction hobs. If your cooktop reports pan-detection errors, cycles power or heats unevenly, test the pan on a correctly sized zone and check that the base is clean and flat when cool.

What Thermo-Signal can and cannot tell you
Thermo-Signal is a visual starting-temperature guide, not a thermometer for the food or oil. It does not confirm that meat has reached a safe internal temperature, nor does it compensate for a high-power induction setting. Use the indicator alongside low-to-medium heat and normal cooking checks.
What are the published specifications?
The following combines Tefal’s product information with measurements publicly listed by CHOICE. Manufacturer claims are identified as such; CHOICE’s measured values are not the same as a manufacturer specification.
| Specification | Published or measured value | How to interpret it |
|---|---|---|
| Product | Tefal Renew Black Ceramic Non-stick Frypan 24cm | Frypan, model C4320423 |
| Nominal diameter | 24cm | Rim-to-rim product size; it is not the flat magnetic base diameter |
| Measured base diameter | 20cm (CHOICE, 2026 listing) | Approximate flat cooking footprint measured by CHOICE |
| Base thickness | 0.5cm (CHOICE, 2026 listing) | CHOICE measurement, not a claimed coating thickness |
| Weight | 0.8kg (CHOICE, 2026 listing) | Light enough for one-handed tossing or draining for many users |
| Cooktops | Gas, electric, ceramic and induction | Tefal compatibility claim |
| Coating | Inoceram Glide ceramic non-stick | Tefal’s coating name and release claim |
| Heat indicator | Thermo-Signal | Indicates the intended starting-temperature range |
| Country of origin | France (CHOICE, 2026 listing) | Public CHOICE listing information |
| Handle material | Not stated publicly | Confirm in the manual or with Tefal before buying |
| Oven-safe temperature | Not stated publicly | Do not assume oven or grill use without written confirmation |
| Dishwasher status | Not stated publicly | Use the supplied care instructions unless the manual says otherwise |
| Lid | Not confirmed for the frypan listing | The separate Renew Black 24cm sautepan with lid is a different, deeper product |
CHOICE’s expert rating and detailed performance scores are member-only. No public score, durability grade or ease-of-use grade should be inferred from the specifications above.
How does the Inoceram ceramic coating perform?
Tefal calls the surface Inoceram Glide and positions it as a ceramic non-stick coating intended to release food easily and simplify cleaning. The company claims the cooking surface is 20 times harder than traditional non-stick. The accompanying footnote describes a nano-indentation comparison performed by an external laboratory.
That is a hardness result, not a promise that the pan will remain non-stick for 20 times longer, tolerate any utensil or survive any cleaning method. Ceramic coatings can lose release performance when repeatedly overheated, abraded or exposed to thermal shock. The most useful way to treat the 20-times statement is as a manufacturer-reported laboratory comparison, not an independently verified lifetime.

What is disclosed about chemicals?
Tefal states that the coating is free of PFOA, lead and cadmium. It says external independent laboratories tested the product against controls stricter than current food-contact regulations. Those are manufacturer disclosures about composition and testing; they do not establish how long the release properties will last in your kitchen.
How should you use the pan on an induction hob?
Careful heat management is more important with a lightweight aluminium pan than simply selecting the highest induction setting. Tefal’s care guidance links sticking with overheating and warns against heating fat or oil until it smokes, burns or turns black.
- Check the base and zone. Make sure the magnetic centre of the pan is clean and dry, then place it centrally on an induction zone close to the 20cm measured base.
- Start at low-to-medium power. Induction transfers energy quickly. Avoid an empty-pan boost setting unless the manual specifically permits it.
- Preheat gradually. Watch Thermo-Signal rather than waiting for oil to smoke. If the indicator changes before you are ready, lower the power.
- Add food and enough fat for the recipe. A ceramic coating is still non-stick cookware, not a guarantee against sticking with dry, sugary or protein-rich foods.
- Keep the oil below its smoking point. Smoking, blackened oil or burnt residue indicates excessive heat and can reduce release performance.
- Adjust power after food goes in. Induction can recover temperature rapidly; medium or low settings are usually more controllable than repeatedly using maximum power.
- Cool before washing. A hot pan plunged into cold water can experience thermal shock and may worsen base movement or coating stress.
How do you prevent sticking and premature wear?
Use the pan for the type of cooking its 24cm format suits, and keep temperatures moderate. The public care information specifically recommends initial oil conditioning for non-stick cookware. Follow the supplied manual for the exact conditioning method, because the correct amount and heating time are not specified in the public listing.
- Use wooden, silicone or other utensils approved by the manual when possible; do not assume that a hardness claim makes metal tools harmless.
- Do not cut food in the pan or drag cookware across the ceramic surface.
- Remove burnt residue by soaking and using a soft sponge rather than abrasive pads or powders.
- Store it so another pan cannot rub against the cooking surface. If stacking is unavoidable, use a soft separator.
- Do not leave an empty pan on a hot zone while you prepare ingredients.
If food begins sticking suddenly, first consider heat history rather than adding more oil. Overheating, smoking oil and residue buildup are the failure modes Tefal’s instructions call out most clearly.
Is it dishwasher-safe or oven-safe?
The public product information reviewed for this model does not establish a dishwasher-safe rating, an oven-safe temperature, a grill limit or the handle material. Those omissions are important because the handle and any exterior components can have lower temperature limits than the pan body.

Before using an oven, broiler or dishwasher, check the printed manual supplied with C4320423 or obtain written confirmation from Tefal support. Do not transfer an oven rating from another Renew model: cookware in the same range can use different handles, fittings or lids. Until the manual confirms otherwise, hand-wash the cooled pan and keep it on the stovetop.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Are the recycled-aluminium claims meaningful?
Tefal describes the body as 100% recycled aluminium. Its 2026-edition eco-design information says recycled materials make up a minimum of 77% of the total product, packaging is 90% recycled cardboard, and the product is a minimum of 82% recyclable excluding handles and subject to appropriate sorting facilities.
These figures describe material content and design intent, not a guarantee that every local recycling service will accept the finished pan. The 77% figure is for the total product rather than the body alone, while the 82% recyclability figure excludes handles and depends on suitable sorting infrastructure. They are useful disclosures, but they should be read as Tefal’s manufacturer claims rather than an independently audited lifecycle assessment.
How does it compare with other 24cm ceramic frypans?
A fair comparison should look beyond the words ceramic and induction. The public data for this pan is more detailed than the data supplied for unnamed alternatives, so the table separates established information from points you must verify for another model.
| Comparison point | Renew Black frypan C4320423 | Typical competing 24cm ceramic frypan | What to check |
|---|---|---|---|
| Induction compatibility | Claimed for induction, gas, electric and ceramic | Not stated for a specific model | Look for an induction symbol and base construction, not just the word ceramic |
| Flat cooking footprint | 20cm measured base (CHOICE, 2026) | Not stated | Compare measured base size with your induction zone |
| Weight | 0.8kg measured by CHOICE | Not stated | Heavier pans may feel steadier; lighter pans are easier to lift |
| Heat guidance | Thermo-Signal | Not stated | Check whether an indicator is included and what it signals |
| Durability evidence | Manufacturer claim of 20-times-harder surface from external-lab nano-indentation testing | Not stated | Ask whether a claim is hardness, abrasion testing or a verified use-life result |
| Chemical disclosures | Tefal states no PFOA, lead or cadmium and cites independent laboratory testing | Not stated | Read the exact compliance statement for the model and region |
| Dishwasher and oven limits | Not stated publicly | Not stated | Require a manual rating before buying for those uses |
| Lid | Not confirmed for this frypan | Varies | Check package contents; a lid changes the pan’s usefulness for steaming and covered cooking |
| Price evidence | $109.99 RRP, with sale snapshots below | Not stated | Compare delivered price, warranty and availability on the same date |
What about the same-range sautepan?
The Renew Black 24cm Sautepan with Lid (C4323223) adds depth and a lid, but it is not a like-for-like replacement for a shallow frypan. Choose it when covered, higher-volume cooking matters more than easy flipping and low sidewalls. Its existence does not confirm the frypan’s lid, oven rating or performance.

How much does the Tefal Renew Black 24cm cost?
Tefal Australia showed a $109.99 regular price and a $43.99 sale price when its page was crawled; the item was marked sold out at that snapshot. Victoria’s Basement showed a $109.99 RRP and a $39.99 sale price and marked it in stock. David Jones showed $109.99 and out of stock. These are time-sensitive Australian price and stock observations, not permanent prices or a guarantee that a retailer still carries the model.
At $109.99, the value case rests on the induction base, temperature indicator, light 0.8kg measured weight and the disclosed material claims. At roughly $40–$44, it competes more favourably with other 24cm ceramic pans, but you should still check the manual, warranty terms and replacement availability before buying. The public information does not state a warranty length, so obtain that detail from the seller or Tefal for your region.
What are the main advantages and drawbacks?
Advantages
- Designed for induction as well as gas, electric and ceramic cooktops.
- Thermo-Signal provides a repeatable visual cue for starting a recipe.
- At 0.8kg, it is relatively easy to lift and manoeuvre.
- Inoceram Glide is marketed for easy release and cleaning.
- Tefal publishes specific recycled-material and recyclability figures instead of only using a general eco label.
- The measured 20cm base gives a clearer expectation of induction contact than the 24cm rim alone.
Drawbacks and uncertainties
- The 20-times-harder statement is a manufacturer laboratory comparison, not a service-life guarantee.
- Public CHOICE pages do not reveal the expert rating or detailed performance scores.
- Oven, broiler, dishwasher and handle specifications are not publicly established for this listing.
- The heated base was recorded as concave, and the magnetic area does not extend to the full rim.
- Regular pricing is relatively high for a 24cm pan, while sale stock is inconsistent.
- A lid is not confirmed for the frypan, so covered cooking may require separate cookware.
Who should buy this pan?
It makes the most sense for an induction user who values a lightweight pan, a visual heat cue and published material disclosures, and who is comfortable hand-washing until the manual confirms otherwise. It is also a reasonable sale purchase when the price is close to $40 and the retailer provides clear return and warranty terms.
Be more cautious at the $109.99 RRP if you need verified oven or dishwasher use, a supplied lid, a documented long-term durability score or a large magnetic footprint. In those cases, select a model whose manual states those specifications explicitly rather than paying for assumptions.
Recommended Free Tools
What should you check before ordering?
- Confirm the exact model number is C4320423; similarly named Renew products can have different shapes and fittings.
- Check the retailer’s current stock, delivered price and return policy on the day you order.
- Ask for the regional manual or written support response covering oven, broiler, dishwasher and utensil use.
- Measure your induction zone and compare it with the 20cm measured base.
- Confirm whether the package contains only the frypan or includes any lid or protector.
- Record the warranty period and the process for coating or base claims.
- Plan storage that prevents contact between the ceramic surface and other cookware.
What is the final verdict?
The Tefal Renew Black 24cm C4320423 is a well-specified, induction-compatible ceramic frypan with useful heat guidance and a manageable 0.8kg measured weight. Its strongest evidence is the combination of published cooktop compatibility, Thermo-Signal, the 20cm measured base and transparent material disclosures. Its weakest points are the unknown public test score, unconfirmed oven and dishwasher limits, uncertain lid status and the fact that the durability headline is a hardness comparison rather than a lifespan test.

Frequently Asked Questions
Can I use this pan under a grill or broiler?
The available product information does not state a grill or broiler limit. Treat broiler use as unconfirmed and obtain the exact temperature rating from the C4320423 manual or Tefal support before exposing the handle or coating to direct overhead heat.
Does Thermo-Signal tell me when my food is cooked?
No. It is intended to indicate the pan’s starting-temperature range. Food doneness and safe internal temperature still require normal recipe timing and, where appropriate, a food thermometer.
What is the practical difference between the 24cm rim and the 20cm base?
The 24cm figure describes the nominal pan size, while CHOICE measured a 20cm base. The smaller figure is the better guide to the flat magnetic area that contacts an induction zone and to the space available for ingredients.
How can I confirm the warranty for an Australian purchase?
Warranty length and claim procedures are not stated in the public specifications summarized here. Ask the retailer or Tefal Australia for the written warranty that applies to your purchase and keep the receipt and model number.
