Thanks for bringing up this topic, Joan. I use EZsoy, also, and add my FO and dye chip at 175....and I STILL have problems with certain colors producing those little spots. I've even cut the dye chips into tiny pieces, stirred for a good 3 minutes or more to disolve them and still end up with those spots. I'm going to try the heat gun tip. But what would you put the dye chip in to heat/melt it??? A large spoon?...a Dixie cup?
