Preparation of Ultramarine (Video)


Greetings fellow nerds (lol)

As a long-time lurker of sciencemadness I have learned quite a lot from this community. In fact, I am now working on a chemistry degree with a huge head start provided by my many cumulative hours of perusing this website.

A few months ago, I saw a post here by Arcaeca about making ultramarine blue. This led me down a whole lengthy process of also doing this, but with the resources available at the community college where I'm currently taking all the classes I can take before transferring to a university.

Since there was not a single video on Youtube depicting this synthesis (none that I could find anyway), I took it upon myself to document what I was doing and spent some time editing the video.

Hope you check it out and like what you see!

That was a well put-together informative video! Making ultramarine blue is a project I've been wanting to do for a while. After the furnace project, of course.

Probably the varied palette of the batches is a result of very small variations in composition, temperature et cetera.

Ultramarines are probably the most difficult pigments to make and reproduce, Kudos for even attempting this and getting a result.
