A brief personal update before getting into the art stuff. Hopefully I have dealt with the scammers. Paypal was not helpful. Ko-fi found nothing scammy in their profiles. It seems that the old school instant refund worked in my favor. Though I did report all of the accounts to Paypal and Ko-Fi.
Outside of that my wife had a minor surgery two weeks ago and I stayed home from work to make sure she was okay post surgery. I always find these occasions* stressful and anxiety provoking. That said, like the last time I spent with someone post surgery, I mostly cooked, cleaned and watched her sleep. And that’s what I did for the last week. She’s fine now and back to her usual self.
As is usual after the holidays and time spent away from work, I was behind on all work related things and it meant that when I returned I had more work to do than usual. very annoying. Also because I was distracted, I forgot to set up my out of office responder (for the surgery time off), so I returned to… a hundred emails and several surprise meetings.

Apparently finding Spectrafix set off a deep dive on casein for me. I’ve been experimenting with casein based binders and glue since whenever I first posted about it, what 6 months ago?
My latest experiment was to test out washing soda versus borax and use a slightly more simple method of making the glue base. I tried this in my first round but because it requires TIME I got impatient and used a faster method for making my binder.
In this method you mix up the borax with the water, let it cool and then mix it in with casein powder that has not been hydrated, instead you mix in the borax water, mix well, and let it sit. Of course I cannot now find the artist’s blog where I first sourced this info. I really do need to take better digital notes when doing online research.
This produces a thick viscous glue that reminds me of methyl cellulose glues or rabbit skin glue. IYKYK.
The recipe for this method:
- 40g casein
- 16g borax
- 125ml water
Mix borax into water. Stir until all crystals are in solution. Let cool. Add to casein. Mix well. Let sit for at least 12 hours.
Then add in an equal amount of alcohol by volume. I prefer ethyl but isopropyl will work. Iso alcohol stinks and is toxic, so you have to be careful of spraying it. At this point the alcohol is acting to thin and preserve the casein glue.
To turn this into a fixative you’ll need to blend it with more alcohol. Roughly a 20% mix will create a mix that can be sprayed. For a 20% mix you put one measure of the casein mix and 4 measures of alcohol. I would do this in a large bottle and set it aside for a day.
The downside to this is that when the thick viscous glue is mixed with alcohol “stuff” settles out of the mix. I’m unclear as to WHAT is exactly settling out of the mix, but it looks like casein- it is white and sticky. Also the mix itself, once the alcohol to casein ratios get to about 4:1 turns whiteish, though dries clear. I wonder if the proteins are denaturing and dropping out of solution.
I suspect that this mix, once settled, is what you get in the Spectrafix concentrate bottles. I made a 20% solution of my DIY fix solution and it looks and responds much like real spectra fix. It’s not quite as strong a fixative as real spectra fix.
I admit I began exploring this because of the expense of Spectrafix. I no longer had a spot to buy it locally (RIP A&C Saugus) and the added shipping costs from Blick jump the price up substantially.
I get why it is so expensive now. The making of it take time, it’s not overly labor intensive but it is very time intensive and I’m sure the experimentation to create a product that is shelf stable and effective was expensive.
