Thick Potion is a useless kind of potion. You can’t use it to brew other potions.
In this Brief Guide we will tell you how to make Thick Potion in the Minecraft Survival Mode. To get that, you first need to make a Water Bottle. Then you have to go into the Nether to get Glowstone Dust, and have to use the Brewing Stand to make the required potion.
Enter in Nether
First of all, enter into the Nether and use a potion of fire resistance so that you can avoid the damages.
After that, the required item that you have to find is Glowstone dust. You will need to find a glow stone in order to get glow stone dust. Smash the stones using your pickaxe to collect glow stone dust.
Thick Potion using Brewing Stand
Make your way towards the brewing stand and put glowstone dust in the upper box and a water bottle in the lower box of the brewing stand and wait for a few moments until you get a thick potion in place of the water bottle. Add this potion into your inventory to use it later.
