As noted alumina will not melt and needs to be handled properly.
Over the years I stopped adding it to wax ( as it settles out) instead I dip my cut sponge in wax and dip it into a small bowl of alumina powder.
You have to be careful it does not run down the pot. I usually only use alumina on 1/2 of the lidded form the top or bottom then just straight wax on the sponge on the other 1/2.This process is fast and precise . Let these two pieces dry before putting the lid on.Then after glazing I sponge the edge once more with a wet sponge to remove any glaze drops.
If the glaze gets any hydrate on it it will be rough and dry so you need to be carefull
Now as to your wax it burns off not runs off so thats not the issue. No matter what kind you use
I use mobil Ceramul A from Laguna-I think its sold in small amounts as I buy it in 5 gallons buckets-I use one up very 5 years or so.
As far as it running did that happen when you applied it? As thats the only time it can run down.

Research Grade a Alumina Powder 10-15nm, Research Grade a-Alumina Oxide Nanopowders 150-500 Nano, Alumina 30c (Health and Beauty)

Can you advise which type I should get?
