Can I mix black glaze to blue to make it darker?

I just got home and realized I need a navy blue color, but I have black and royal blue. Can I add blue and black to make navy or will it show up funny when it is fired? Thanks.

Glaze definitely doesn't work like paint. With paint you mix black with blue and you get a darker blue. If you are using regular glaze the chance are really good that if you mix black and blue you will get something entirely different, maybe even a lighter color!

On the other hand, if you are using "underglazes", they are much more stable and may very well mix just like paint to create a "what you see is what you get" result.

Check the labels on your bottles to see if they are glaze or underglaze. Besides that, the best way to know is to try it on a sample pot and see what happens. Many a cool glaze was created by putting two glazes together and getting a happy surprise!!!

Hope that helps,
