Engineered quartz benchtops are banned in Australia, so the real 2026 choice is between the two legal successors: sintered stone and mineral (recycled-glass) surfaces. Sintered stone is the stronger pick for most kitchens because it contains no resin, making it more heat and UV resistant than both old quartz and resin-bound mineral surfaces. Quartz was prohibited from 1 July 2024 (Safe Work Australia).
- Engineered quartz is banned in Australia (manufacture, supply and installation prohibited from 1 July 2024) — it is no longer a benchtop you can buy new.
- Two legal replacements exist: sintered stone (fired, no resin) and mineral surfaces (mostly recycled glass, bound with resin).
- Sintered stone is the only resin-free option, so it leads on direct heat, UV and outdoor use, and never needs sealing.
- Mineral surfaces are legal because glass is amorphous (under 1% crystalline silica), but their resin binder still limits heat and UV like quartz did.
Why Quartz Benchtops Are Banned in Australia
Engineered quartz is banned because cutting it produced dangerous crystalline silica dust. Traditional quartz benchtops were made by binding up to about 90% crushed quartz with polymer resin, giving a slab that was very high in crystalline silica. Fabricating it generated fine dust linked to silicosis, an incurable lung disease. From 1 July 2024 the manufacture, supply, processing and installation of engineered stone with more than 1% crystalline silica was prohibited nationwide, with import enforcement from 1 January 2025, according to Safe Work Australia. In practice, you can no longer buy a new quartz benchtop in Australia.
What Replaced Quartz? Mineral Surface vs Sintered Stone
Quartz has two legal successors, and they are not the same. Mineral surfaces are engineered benchtops made largely from recycled glass — around 80% — bound with a UV-stable resin. Because glass is amorphous rather than crystalline, the finished slab stays under the 1% crystalline silica threshold, so it sits outside the ban; Caesarstone's ICON range is a well-known example. Sintered stone is different again: it is made from natural minerals compacted and fired above 1200°C with no resin at all. The key distinction is the binder — mineral surfaces still contain resin, while sintered stone contains none, which is why sintered stone handles heat and UV better.
Is Sintered Stone Affected by the Ban?
Sintered stone is not banned because it contains no resin binder. The prohibition targets resin-bound engineered stone specifically, so resin-free materials such as sintered stone and porcelain sit outside it. Importantly, sintered stone is not silica-free — it does contain crystalline silica — so wet cutting, on-tool dust extraction and respiratory protection still apply in the workshop. Once installed, the finished benchtop is inert and releases no silica dust in the home. For the full regulatory detail, see our guide on whether sintered stone is affected by the ban.
Sintered Stone vs Quartz vs Mineral Surface: Full Comparison
Sintered stone is the only one of the three with no resin, which is what gives it the edge on heat, UV and outdoor use. The table sets quartz (now banned), mineral surface and sintered stone side by side.
| Property | Engineered Quartz | Mineral Surface | Sintered Stone |
|---|---|---|---|
| Made from | Crushed quartz + resin | ~80% recycled glass + resin | Natural minerals, fired >1200°C |
| Resin binder | Yes | Yes | No |
| Crystalline silica | Up to ~90% | Under 1% (amorphous glass) | Contains silica (not silica-free) |
| AU ban status | Banned (1 Jul 2024) | Not banned | Not banned |
| Heat resistance | Resin scorches ~150°C | Resin limits heat | Direct hot cookware |
| UV / outdoor | Not for outdoors | Limited by resin | UV-stable, warranted outdoors |
| Porosity / sealing | No sealing | No sealing | Non-porous — never seal |
| Scratch (Mohs) | ~7 | ~6–7 | ~6–7 |

Heat, UV and Maintenance in Everyday Use
Sintered stone outperforms both quartz and mineral surfaces on heat and sunlight because it has no resin to degrade. You can place hot cookware directly on a sintered surface, while a resin-bound top can scorch or discolour under sustained heat above roughly 150°C. Outdoors, resin-bound surfaces are generally not recommended because UV can fade them, whereas sintered stone is UV-stable and frost resistant, making it suitable for alfresco kitchens and facades. Day to day, all three wipe clean, but sintered stone's non-porous surface shrugs off acids, oils and stains without sealing. Asetica's Taj Mahal and warmer-toned Taj Mahal Royale reproduce the look of premium quartzite with none of those limitations.
Which Should You Choose?
Choose sintered stone if you want the best all-round performer — it is the only resin-free option, so it leads on heat, UV, outdoor use and sealing-free maintenance. A mineral surface is a reasonable, legal choice if you specifically want a high recycled-glass content and only ever use it indoors, but its resin binder means it behaves more like the quartz it replaced. If you liked the look of white quartz, sintered stone offers the same marble-look palette in finishes such as Taj Mahal, Taj Mahal Royale, Calacatta White and Bianco Lasa. For a wider material view, compare it with sintered stone and porcelain too.

Frequently Asked Questions
Is quartz banned in Australia?
Engineered (manufactured) quartz is banned in Australia. From 1 July 2024, the manufacture, supply, processing and installation of engineered stone with more than 1% crystalline silica was prohibited nationally, with import enforcement from 1 January 2025. The ban targets resin-bound engineered stone, which includes traditional quartz benchtops, because cutting it produced the silica dust linked to silicosis.
What replaced engineered quartz benchtops?
Two surfaces have replaced engineered quartz in Australia: sintered stone (and porcelain), which is fired with no resin, and mineral surfaces made mostly from recycled glass. Mineral surfaces are legal because glass is amorphous, keeping crystalline silica under the 1% ban threshold. Sintered stone is the only one of these that contains no resin at all.
What is a mineral surface benchtop?
A mineral surface is an engineered benchtop made largely from recycled glass (around 80%) bound with a UV-stable resin or epoxy. Because glass is amorphous, the slab stays under 1% crystalline silica, so it sits outside Australia's engineered stone ban. Caesarstone's ICON range is a well-known example. It still contains a resin binder, unlike sintered stone.
Is sintered stone or mineral surface better?
Both are legal in Australia, but sintered stone performs better on heat and sunlight because it contains no resin. Mineral surfaces are bound with resin, so they share quartz's limitations: they can scorch under high heat and are generally not warranted for outdoor use. Sintered stone takes direct hot cookware and is UV-stable for alfresco kitchens.
Is sintered stone affected by the engineered stone ban?
No. Sintered stone is excluded from Australia's engineered stone ban because it contains no resin binder, unlike engineered quartz. Safe Work Australia confirms resin-free products such as sintered stone and porcelain fall outside the prohibition. Sintered stone still contains crystalline silica, so standard dust controls apply during fabrication, but the installed surface poses no silica risk to occupants.
Does sintered stone contain silica?
Yes. Sintered stone contains crystalline silica, so it is not silica-free. It is excluded from the engineered stone ban because it contains no resin, not because it is free of silica. Cutting and polishing still require wet processing, on-tool dust extraction and respiratory protection, but the finished, installed benchtop releases no silica dust in the home.
Can sintered stone go outdoors when quartz cannot?
Yes. Sintered stone is UV-stable and frost resistant, so it is warranted for outdoor kitchens and sun-exposed benchtops. Engineered quartz and resin-bound mineral surfaces are generally not recommended outdoors because UV can fade or yellow the resin over time. This makes sintered stone the more reliable surface for alfresco areas and facades.
