Let's set up the materials. Hold down Z, switch to Rendered. The light we had in the scene can be moved. You can also increase the radius, the shadows were softer, and increase the intensity. If necessary, you can change the color, but I don't recommend changing the light too much. You can slightly move it towards yellow, then it will be warm, or slightly move it towards blue, then it will be cool light. By default, we have white light, that is, saturation at 0. Let's set up the materials

Let's add a plane on which our jug will stand so that we can see the падающую shadow.

We select the jug, go to material settings. There is some material, if we don't need this material, we press minus, we press add new. We choose the color of the jug. You can remember what colors jugs generally come in.

And we change the Roughness parameter, this is our roughness value, to something more acceptable, so that it either shines or, on the contrary, is more matte, because ceramics can be completely different. And we call this material Keramic.

We also select the handles, we also choose this Keramic material.

On the sticker, we make a different material. We press New, we will make a blue sticker. It can be more shiny, or, on the contrary, more matte, compared to the jug.
