Acrylic enamel is good for painting glass. If you want spray paint, many are formulated for glass and other surfaces. Check the label. Decoart also makes a glass paint for decorative painting.

there are craft paints that you can put in the oven so it can be semi-permanent. For example, check out this project:

Hi Liz, it will really depend on what you are doing and if they are going to be for a decorative purpose or for use. if you are using them for decoration, Annie Sloan Chalk paint works well and sticks beautifully to glass.

If you want to put liquid inside, pain the outside of the bottles.

You've gotten some good answers. I'll add that Mod Podge has a dishwasher safe clear coat that will add some sturdiness over anything you paint.

If you are going to paint the entire surface or stencil them, I always vote for spray paint. https://www.hometalk.com/43410780/glass-bottle-makeover

Use a spray paint made for plastic, it will also work on glass.

Hello. I use the plastic friendly spray paint with primer. I use that on glass and ceramics all the time.

I use chalk paint. Almost any kind will do, Rustoleum has a good brand of Chalked paint
