Titration!

I've been working on a couple watercolor paintings of labware recently. I've always loved glassware and glass sculptures. Labware is no different. Though its purpose is almost always utilitarian, I can't help but find it beautiful in its own way.

This is a painting of a titration in an Erlenmeyer flask. Titrations are used to figure out the strength (concentration) of a solution. A common titration often used in general chemistry labs is to start with an unknown acidic solution with an indicator (in my painting it is phenylphthalein) added. Carefully measured amounts of a known concentration of basic solution are added until the original solution briefly changes color. From that point, calculations are made to determine the concentration of the original solution.

My painting captures the moment when the phenylphthalein has changed color due to the addition of drops of basic solution.





I'd love to hear your thoughts!

Painting through the Universe: Eskimo Nebula

I've been taking a little break from planets for a bit and have gotten very excited about painting nebulae. At first I just played around with some different methods of painting them but last week I attempted my first real nebula.

I was overwhelmed by the sheer number of beautiful nebulae to choose from and so sent a quick request out to twitter for suggestions. The Eskimo Nebula came back as a suggestion from Adam P. Knave. I have to admit, at first I was not very confident about attempting this particular nebula but I decided to just go for it and see what happened. This is the result!
