Gas hob (surface), color - white.

Well, traditionally for my models, all objects have correct names in English, there are materials and multi-materials that are also renamed, textures are also renamed. All the textures painted by myself.

[!] IMPORTANT. Materials for rendering V-Ray, if the automatic conversion of materials for Corona Render passes with problems, your scene hangs or is destroyed, I cannot bear responsibility for this. Open and convert the model in a separate scene.

Who works in the V-Ray version is lower than 3.1. Be careful, in the materials in the BRDF section there is a Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable to you.
