I'm debating on which to purchase - a stovetop thermometer or an IR gun. I'm leaning towards an IR gun because it will be more broadly useful (can use for purposes other than just the stove) and I prefer the look of not having a stovetop thermometer on the stove. My stove will be a Woodstock soapstone, will an IR gun work with soapstone? Is a stovetop thermometer preferable for any reason? Do I need to have both? Thanks for your thoughts.
