Sand bath on induction heater?

Trying to get away from oil baths and wonder if sand would work? heated in a iron flat bottom dish, I am thinking yes, but has anyone tried such a thing? Should be safer and less odorous.

Sand bath works great. Heating mantle would be ideal but sand is the next best thing.
Oil and water baths can cause all sorts of problems. Very dangerous too
Just get clean sand

Yeah, sand isn't really the question, its heating it with an induction plate that concerns me, the induction plate heats the metal container on top of it with the use of an induction current, the vessel heats up and so do the contents as a result, however I have not tried this with solid matter like sand. Just looking for any potential "gotcha" on this idea.

The reason I like the induction plate is that it is low profile, digital and very accurate in terms of dialing in temps. And about a third the cost of a heating mantle.

It should work just fine.
sand transfers heat very well and does not smoke or steam or splash.
Sand bath is a centuries old method.
Haven't used one myself in about that long. Heating mantles were thankfully invented in the 30's by glascol
Sand bath makes your hotplate very versatile. Lots cheaper than multiple sized heating mantles.
Oil can really suck to work with in high heat and or lengthy procedures

Anyone else feel like chiming in on this, maybe you also use induction plates in your concentrate manufacturing processes?

Lol. Induction plate probably but you and i are likely the only ones here that have heard of sand bath let alone used one. Half the people reading this are wondering where the butane goes. Try a real science forum like science madness or rhodium if you want re assurance . Many of us remember using sand baths and hot plates as undergrads. Or pick up just about any text book to learn more about the nuances

Sand baths are common old school and we used them before we were able to afford hotplates capable of holding tight tolerance at the low end of their heat range. You can also bury flasks in sand to achieve a mantle effect.

With the plate underneath the sand, the sand wouldn't know how the heat was produced, unless there were metalic ores and oxides in the sand.
