SFA: What's the Answer?

Induction Cooktops and Natural Stone

surfaceresourcemike

Anyone done anything with the Invisacook induction cooktop that is mounted under the stone? Our customer wants to put one under Volga Blue. The area has to be milled down to 1.5 cm and will gradually retain the heat after 10 minutes of cooking. I'm not sure what the stone will do after being heated up and cooled down repeatedly. Thanks for any help.

From what I can tell they do not warranty anything to do with the stone, only their product itself. That's the part that worries me

I would think it would kill the stone. Justin Zacherl Creekside Granite and More 814-657-3294 Justin.zacherl@stonefabricatorsalliance.com

Being milled down that thin in that area sounds like we'd be asking for it to crack.

I have seen quartz countertop crack because of heat created by an induction cooktop. If it was me; No warranty, no way. It's your butt on the line if things go south!

First you would have to ensure the stone being used has ZERO resin coating/filler, otherwise it is going to turn ugly quick. Stone will likely weaken over time specifically in that area due to the thermal cycling. If your client absolutely has to have an under-counter induction cooktop, stick with sintered materials (Dekton®, porcelain, etc.); even then it’s going to create a localized thermal cycling compared to the surrounding area. None of it sounds great from a longevity standpoint. Clearly communicate that your work and material would be as-is unless you want to be tied to "not if but when it fails" issue. Good luck!

I wouldn’t mill it. Find some tile and insert it in that area and support underneath.
