hello,Is there anybody can teld me, what is white part(the pad for paint)? It is seems water(or paint) can float on this pad.

I am confused.

Yep, that's a homemade stay-wet palette. I would highly recommend trying one if you're using any kind of acrylic paint, they're excellent and can save a lot of paint drying out during use.

It's a great idea to make your own if you can as it is far far cheaper than any of the commercial types. The plastic container and the reservoir to hold water are simple, the main difficulty you might have is the paper that will become the palette surface as not all baking parchment is the same. I'm not even sure if this is commonly available where you are in China?

If you do have trouble locating baking parchment something else you might try is good-quality tracing paper or tracing parchment, which can work well for this (but no guarantees, sorry).

Guys, is there something similar for oil paints i.e. oily palette ??
Before I used to place my oil paints in the refrigerator but now that I am married, my wife won't cut my any slack.
Any suggestions?
Cheers

Nicolas, there are disposable paint pallets. They come like pages in a book. Just tear out a page and have fun. One side is shiny and the other dull. I use them all the time. You can put them in a food storage container and put them in the freezer if necessary. When done with them just throw them away. You can buy them in any art supply store.

@Einion, Yes as your said the key point is surface paper I will try some local baking paper and to find which one is the best.
