Ughhh. But I am in contact with hbn lot...
It's a copper Eliminator...my guess is tin dioxide or bismuth.I didn’t get the memo. I have my own dust, but what is Tubb’s Dust?
Do those bottles have a positive seal (airtight), like paper or rubber gasket? It says not recommended for liquid storage.The one pound containers that I use are "Nalgene HDPE Wide Mouth Round Containers" and can be purchased from amazon for around $4.50 apiece. I purchased one for every type of powder that I use.
