Review: Sturdy, heavy-weight - I saw this after looking at similar items made from stainless steel or even tin, and was doubtful they'd be able to withstand an open flame for any length of time. This, on the other hand, is made from the same material as the racks on gas cookers (or at least on mine), so while I've not used it yet, am pretty sure it'll not warp or bend. It's heavy, with a nice solid heft to it, and would think cast-iron is good at distributing heat evenly. It has little notches all around the ring on the bottom, so that it sits securely on the rack of my cooker. I think it should fit on any gas cooker, as the notches are evenly spaced all around the bottom. It raises the pan 1 cm above the normal height, and am intending to use it with a saucepan which is larger than 21 cm diameter, as it was largest I could find. The handle is quite basic, but does the job, feels secure when in place, and fits easily into the opening. It would've been nice to have a heat-proof handle, but with an oven glove or similar, it'll be fine. Mine was a Warehouse Deal (I always look out for them, good bargains!), so I didn't have to pay the postage, but would probably have paid it if necessary. Considering the weight of the item, it seems reasonable and the price is good, too. While it's over 2x the price of the stainless steel ones I saw, it's a different class, quality wise, and will doubtless last many years. As I'm always wishing I could turn the gas down further when simmering, I am sure this will be very handy for stews, soups, custard etc, so would recommend. Review: Worth every penny - Bought this at what I thought was an eye-popping price to replace a cheap one I'd had previously. This one is really heavy and sturdy - it's brilliant. My last one had a handle which had come off within two weeks. The steel went rusty and disintegrated pretty fast. We persevered. When we cleaned the cooker we put it on the side and it made indelible rust marks on the kitchen surface. This one - very heavy - enamelled - brilliant. Perfect heat dissipation for slow simmer. It has a removable handle so that it doesn't get really hot. I think it will be with me for life. Odd to be so enthusiastic about a simmer ring, but it's SOOOOO much better than the last one. ## Features - ILSA Radiant cast iron plate ilsa Cm 21 cooking pot - Home, furniture and DIY - Dimensions: 22x22x2 cm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0007T25ZC | | Best Sellers Rank | 279,941 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 266 in Trivets | | Brand | Ilsa | | Brand Name | Ilsa | | Colour | Black | | Country Of Origin | Italy | | Customer Reviews | 4.4 out of 5 stars 1,942 Reviews | | Global Trade Identification Number | 08000409255218 | | Item Dimensions L x W x Thickness | 22L x 22W x 2Th centimetres | | Item Shape | Round | | Item Type Name | Heat Diffuser | | Item Weight | 250 Grams | | Manufacturer | Ilsa | | Material | Cast Iron | | Material Type | Cast Iron | | Product Care Instructions | Hand Wash Only | | Product care instructions | Hand Wash Only | | Product dimensions | 22L x 22W x 2Th centimetres | | Shape | Round | | UPC | 885172180657 735343004179 | ## Product Details - **Material:** Cast Iron - **Colour:** Black - **Brand:** Ilsa - **Product dimensions:** 22L x 22W x 2Th centimetres - **Shape:** Round ## Images ![Ilsa Heat Diffuser, 8 1/4in, Black - Image 1](https://m.media-amazon.com/images/I/51+Rfj4YXdL.jpg) ## Questions & Answers **Q: Is this for use on gas hob only - my hob is electric?** A: Hi . We bought for our woodburner so that we can slow cook. Not sure re electric **Q: Im still waiting for a delivery date for this item? When will it be shipped?** A: The Ilsa Diffuser is manufactured in Italy. I am suggesting that Italy is prioritising dealing with coranonavirus and deliveries are delayed. **Q: Item b0007t25zc. can you tell me if this goes on top of the gas burner directly and whether you remove the circular disc that sits on top of the flame** A: Hi, you put this on the metal grid that sits above the burner, the same place you would place your cooking pan; you DON'T remove the circular disc that sits on top of the burner flame, NOR do you put in onto the gas burner's circular disc. It sits above this, directly underneath and touching the cooking pan that you will be using. Hope this helps. **Q: Can I use this with different sizes of pan?** A: I can use mine on all four rings on my gas cooker. I think you could use it with any size saucepan you would normally use on a cooker. It is quite heavy and sits very safely over the gas. I love mine and it has meant I can now simmer properly which was impossible to do before. I can thoroughly recommend it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sturdy, heavy-weight *by S***H on 9 May 2017* I saw this after looking at similar items made from stainless steel or even tin, and was doubtful they'd be able to withstand an open flame for any length of time.

Instead I bought a defuser which really works better for me plus the fact it does what it is supposed to do and my saucepans really sit well on it. ## Frequently Bought Together - Ilsa Heat Diffuser, 8 1/4in, Black - Ilsa Heat Diffuser, Made in Italy from Cast Iron, Flame Guard for Simmering, 7-inches - SimmerMat Heat Diffuser - Flame Diffuser Stove Cover Ring - Fire Diffuser for Any Type of Electric or Gas Stove - Dishwasher Safe Stove Top Cover - Steel Plates for Simmering and Slow Cooking - 1 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/56039039-ilsa-heat-diffuser-8-1-4in-black](https://www.desertcart.dk/products/56039039-ilsa-heat-diffuser-8-1-4in-black) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-30*
