Do isomalt items melt quickly in the humidity? I want to make some gems but need to transport them 4 hours from home. There will be stops in between so they won't be in air conditioning the whole time. Should they be packed in a cooler? I have made some sugar items before but never in this heat and humidity. Thanks

Hi, don't know if this helps or not, but I made isomalt coral pieces & left them sitting on the counter overnight. By morning they were showing signs of "melting" & clouding. I would try to keep them out of the humidity as much as possible. I have heard of a medium that absorbs humidity (like that you find in bottles of some meds), but I can't remember what it is called, sorry (dessicant maybe???) anyone know?

Sugar will cool down pretty quicklky once it's poured. I would recommend putting them in an airtight container right away. Remember not to handle them with your bare hands though, as the oils from your fingers will also cause them to cloud. And bunny is correct. It's called dessicant, and I'd suggest using that.

Here is an example of silica gel desiccant. I like the reusable ones in canisters.
