Watercolor tubes and porcelain palettes on plane cargo
I'm travelling from Portland, USA to Florianopolis, Brazil and I wonder if I can check in 15mL metal tubes of watercolor without being damaged by the pressure in the cargo. It will be a total of 4 flights - 2 in the USA and 2 in Brazil. Also, I would like to check in my porcelain palettes with my dry watercolors, but I'm worried that the paints could melt once it gets to Brazil (with the two domestic flights ahead, and the high temperature summer time) and that the porcelain palettes are risking to be broken. The palettes are 4x4in and 4x8in.

The cargo hold is pressurized the same as the passenger cabin is. So your paints won't be effected by pressure changes.
The cargo area will be colder than the cabin (they occasionally heat a section if there are live animals or perishable goods, but not to any high heat level). Likely your checked bags will be in containers in the cold part of the cargo hold and when they reach Brazil will likely still be cool when you claim them in customs.
The only worry about heat would be if your layover time is long (several hours) and if the bags are left sitting in the full sun between flights. But as you will be claiming your bags at customs when you arrive, when they are rechecked they will likely stay in the baggage processing area, rather than being dumped on the tarmac like they would on a domestic to domestic connection.
I would wrap your porcelain palettes in bubble wrap or a bit of foam to protect their fragility and keep them cooler longer.

Each tube of paint must be less than 3.4 ounces, and all tubes must be packed in one clear, zip-top plastic bag along with any other liquids and gels you are carrying on board.Where should watercolor tubes be stored?

With an airtight palette, you just have to wait til they're not runny anymore. If you don't need your setup to be portable, an open palette is fine too. I prefer palettes with little wells to keep my individual source pigments pure, but if you like working with an open, well-less palette, that is fine too.Meeden Heavy Duty Watercolor Palette
