so i've compared it with kitchen salt and this is the result https://twitter.com/kitsunee_udon/status/1266615101794086916

i think martini salt took longer time to melt and fully dry than kitchen salt even tho the claims are the opposite. however it satisfy me because it does left less residue than kitchen salt. it's also spread granulation effect evenly

if you prefer explosion-like-effect(?) more (how to describe this ) i think you should go with kitchen salt. it dries faster but left more residue than martini salt. i use rock salt for cooking so i should pound it first TwT it creates smoother texture than martini salt

plus point for martini salt, it left glittery effect on your painting

if you want to give it a try, you can get it here! https://shopee.co.id/product/1375095/6432588748?smtt=0.0.9 originally it comes with 2 options, white and pink. you can request for the color directly to the seller, there's no difference for the after effect

both are good in my opinion, just use whatever you like based on your result preference :D
