I’ve had 2 microwave ovens…both Kenmore & both have been unsatisfactoryy in fusing glass. Its been suggested to me that good ovens to use are Sharpe & Emerson however I’m unable to find either in my area. There are a lot of Danbys & Panasonics. Has anybody used either of these successfully…otherwise, can you please share with me what Brand of microwave oven you ( anyone ?) are using….
