Happy Friday! With my modern bohemian DIY on-line jewelry class coming up, I’ve been playing around with plaster and molding techniques,which I find really creative and interesting. I came up with this fun DIY monogrammed vase made from plaster and a recycled bottle. The best part is I used my own garbage to make it! Ok, in my defense, it was a cleaned and washed recycled bottle, and a cleaned and washed milk carton.
Did you ever make those candles in grade school where you put a wick in the bottom of a milk carton and then poured in the wax and voila, you had a candle? This easy plaster casting idea can also be used with concrete. You might have done this right after you finished a macrame owl project. This is the same kind of premise with molding in a cleaned and washed milk carton. I swear I did wash it.

It’s much easier than you think! I used a thick plastic bottle that wouldn’t break when it was cast…That would be bad.
The big thing is to have your milk container and bottle ready to go, plaster and concrete harden fast.
I used craft plaster from Hobby Lobby, not the industrial stuff from the hardware store. Make sure you read all of the instructions on the side and follow all of the safety precautions. Plaster actually generates heat when it sets and can burn your skin, and it is also a respiratory irritant. I recommend doing this outside and wearing gloves, goggles and a mask because of the dust when mixing. If you are looking for supplies, you can find many of my favorite casting and molding supplies in my Amazon Store.
Now that I have completely scared you off of this project, mixed dried plaster it in a cup with water until it is the consistency of runny pancake batter. How much you need depends on your bottle size. I used a full cup.
Make sure to fill the bottle with sand or small stones to weigh it down or it will float up when you are casting.
Pour all of your plaster in around the bottle and let it set. Now, plaster can also expand slightly when it cures and like I said, it also creates heat, so put it somewhere stable and steady, away for children, and leave it be for a few hours.You can even leave it out overnight if it’s not going to rain and check it in the morning.
I decided to monogram mine. I will tell you I should have sealed the plaster first with a product like Mod Podge or a flat varnish because it sucked up the ink and feathered a little. It also showed smudges fast too. So make sure you seal before stamping.
I stamped a brown ink and then StazOn gold ink
Use StazOn Ink it really does stay on hard to adhere surfaces and doesn’t smudge once it’s cured. If you’re interested in carving your own stamps, you can see this post here.
Once you get used to working with plaster, making a vase with plaster is a fun and easy and inexpensive project!!!
