Alright then xD So the washing was done in a container with a screw lid. It was filled to a degree with the solution for washing and then shaken vigorously for a minute. After that i would let it settle out for a few minutes and then the exess liquid was decanted off into a seperste container. i first washed it a few times with 90% isopropyl alcohol, then multiple times with sterile saline solution. As a last washing (for the ink tries) i used prontolind desinfectant and after decanting it off i filled it again with it for storage. I prepared the powder for scarification rubbing a bit differently. I first washed once with isopropyl alcohol, then a few times with sterile saline solution and then twice with 99.9% isopropyl alcohol from the pharmacy. After that i would spread it out in a sterile container and dry it there. Afterwards i’d check the washing solutions to see if something washed out. Strontium aluminate is very resistent to heat (up to 800°c without lost of phosphorescent properties.) so using an autoclave sterilisation should work. Everything on your own risk. Oh and please ton’t use strontium aluminates from ebay. Often it’s just relabled zinc sulfide on there.
