Painting Dishes

Polypropylene is a type of plastic product.
I would not paint/glaze that nor bake it in the oven.
It will probably melt or degrade.
However, polypropylene food containers are microwaveable.

google up DIY projects. Here is one that will work for you. Your platter and paint need to be exactly the kind they say to use. http://witandwhistle.com/2011/12/21/diy-chalkboard-servin...

I would talk to someone at craft store (Michael's or Hobby Lobby). I'm sure they sell exactly what you're looking for.

But I wouldn't buy a platter and then try to find paint to work with it. Your chances of finding something that will work are much, much higher if you buy them together.

Or you could use nontoxic durable paint on the polypropylene. Ask at a craft store. No need to bake it. Plastic does not withstand baking and with the right paint you don't have to.

How about getting a wooden tray and painting and sealing it? Or decoupage it and then put a clear glass dish inside it to actually hold the food. This way the tray doesn't get dirty and need washing.

Or see if there is a ceramic store near you that sells greenware (unfired ceramics) that you can glaze and seal? Usually for a small fee they will fire it for you. And you can make sure it's sealed with non-toxic food safe products.

You have to be sure that both the tray/platter and the paint are food safe. A lot of the things you find in craft stores are not food safe because of how they were made. Especially paints and plastic things but even glass things, too. I bought glass jars at Christmas one year to put a homemade meat rub in. I got them home and found a sticker on the bottom that said they were not food safe. It took me stops at several stores before I found glass containers that were food safe. I would be careful with baking something painted. A lot of paints are flammable, even at low temps.

Your best bet might be finding one of the painting business where you paint a ceramic item and then they fire it in a kiln. Our local one is called Color Me Mine. But, if you want it for Father's Day do it ahead of time. It usually takes a week for them to fire it. (They wait until they have the kiln filled.)

I wouldn't do it unless it is for decoration only. If you can find a ceramic shop near you you would be wise to do so. They can point you in the right direction for a tray and paints that can be fired to a high enough temp to burn out the lead in the paint and glaze. The platter you have could not be fired high enough in your oven to cure the paint. The firing temp would be like 1800 degrees for several hours with a cool down period of 8 hours before it can come out the kiln. My knowledge comes from doing ceramics as a hobby and having a kiln in the garage not presently hooked up.

I don't think you can bake it. Check with the manufacturer of the platter you want to buy and paint.
