Question about lighting tutorial

[online_mad2]

I want to ask how you set the glass shader ?
because what I set seem not very like a glass
Can you point out what's wrong with my settings?

To H20
would you mind telling me more detail about the first page, that

1) 創立一個Lamert材質，把Ambient設為0.1，在Color及Incandescence連接Ramp。
2) Ramp的類型改用Circular Ramp把顏色改為中心白色，外圍灰色

I do not know whether i am correct in this part.

About Glass Shader:
首先你要 load 左 mental ray 先, 去 plugin manager load "mayatomr.mll" 呢個 plugin

跟住就照 tutorial 入面 set:
1) 在Mental ray的Materials裡面，建立一個*Dielectric Material。
2) Col 就是材質本身的顏色;Ior(Index of Refraction)為折射率，根據真實的玻璃折射率，我在這裡改做1.65。
