This is what I used


//...............................................
global_settings {
        max_trace_level 255
        photons {
                count 1000000
                autostop 0
                jitter .1
                }
        }

// light source just inside the ashtray
light_source{ 0 color rgb <1,1,1>*4 translate <-160,0.51,40>
        photons {
                refraction on
                reflection on
        }}

#declare YourBlobbyGlassThing =
        blob.................. etc
        
        material { M_Glass3 }
        photons {
                target
                refraction on
                reflection on
                collect on
                }

        }
        
object { YourBlobbyGlassThing }

With the ashtray this used ~1Gb memory and 70~80 hours to render at 1200 x
600 pixels, so you might want to lower the count first :)
