I recently purchased what I believed to be a balti dish. It turned out, it was just a serving dish.     It is described as     A Quality Stainless Steel Balti Dish 15cm in diameter. Balti dishes are perfect for serving your Indian food & Curry Dishes the traditional Restaurant way. Two handles on either side for easy handling.   Are there any obvious/common dangers cooking with this on a gas hob? Or is the risk more that the material won't take the heat and could break (spilling the food)? 
I would say that is too thin to use on a hob. There isn't an Indian restaurant in the country that uses them to actually cook in: they cook in a proper pan and then dump it in a dish like this to serve.
