    Default Making spray out of powder

    I got some crox and ceox, but I don't like to use it in powder form, it is just too messy and inconvenient. I was thinking about making my own spray out of them, I just don't know what should I put in the mix. I want to make a it water soluble, because I want to spray it on various kinds of strop surfaces, and I want to try them on hones too. Is it enough if I just put some water and a bit of alcohol in it, or do I need something else too? Also, about how much powder for about 100ml of spray?

    I hope someone already messed with this too, so I can get some advice on this

    This is highly difficult and so far I have done it only once. I mixed chromium oxide 1:1 with ethanol. That means one part (volume) Cr2O3 on 1 part (volume) Ethanol.
    You have to shake it thoroughly before use! I would recommend more Ethanol an less powder than I used

    Than I will go to a pharmacy and buy some ethanol, and maybe they will have some kind of small spray bottle for it too. Thanks for the input, I will report back as soon as I can with the results.

    I haven't had any problems with using the powder. If I were going to try to get it in a solution to spray onto other surfaces I think I would start with a chrome oxide artists paint. That way I could thin it down with the appropriate solvents (depending on whether it was an oil paint or an acrylic paint) to get the consistancy I wanted. Not wanting to sacrifice anything expensive in case it didn't work I would start with a balsa strop and if that were successful move onto linen and then leather. I would do quite a bit of research before trying it on a hone in order to find out if the paint solvents could react with the hone especially if it is a synthetic hone.

    not speaking from experience here, but what about soap and water?

    Iīm not sure if soap and water would work. Of course the surfactants in the solution could trap small amounts of particles and create a dispersion.
    But I highly doubt this will be easy. I wouldnīt recommend Oil or Acrylic paint either, these tend to get very hard and in my opinion ruin the surface of the strop.

    I have two different ways of pasting a strop depending on the material used.
    If it is leather I avoid alcohol and mix a drop of oil with a pinch of powder and apply it with a brush. No real mess here.
    If itīs not leather oil can clogg the surface. I avoid oil for felt and linen. Here I prefer alcohol.

    Ask a pharmacist, preferably one who has specially trained in compounding. Compounding is close to magic... they know all sorts of tricks to get nonsoluble particles to suspend nicely in different media. I'll ask my wife (who's a pharmacist) about this. I probably won't have an answer to post until tomorrow, because she's working a long day.

    Spraying CrOx, Wouldn't the cause all sorts of mess?

    I use the brush method and that works well

    I have tried mixing diamond powders with isopropyl alcohol and water and it sorta worked.
    Anyway, This is the thread but its probably no good for CrOx http://straightrazorpalace.com/strop...r-0-1-2-m.html

    Ethanol is found at the liquor store. Depending on where you live, it will come in 175 or 195 proof(Everclear).
    However, I would be careful about spraying leather with alcohol as it may damage it.

    Compound you mention are not going to be soluble in any polar or organinc solvent that I can think of. As mentioned you can mix and shake when needed but start experimenting with about a gram of compound to 10 ml of water, shake and spray very light even coat.

    If you ever use a strop dressing would it not be a good idea to mix and work in at that time?
