Rushing a suggestion probably isn't a good idea. This makes it seem like you were assigned a project to come up with an element and did it last second- if you have an idea, flesh it out fully and think of what it should do before suggesting it.
Also, try to think of ideas that can't easily be replicated in game. We have salt which is white and melts at a high temperature, and yeast already expands with heat. This really wouldn't add much
Why sugar melts? Sugar should become BCOL + WTRV at higher temperatures.
I want SUGR too... there is salt and it would be nice to have a little sweet.
