How to make Sodium dichromate I've been trying to make Sodium dichromate $\ce{Na2Cr2O7}$ by following these steps:


Dissolve an inox spoon in $\ce{H2SO4}$
Filter the solution
Dissolve the obtained sludge in $\ce{NaClO}$
Heat the solution until slurries appear
Filter the solution


The solution I obtained was yellowish (light yellow), I tried to add some acid to see the orange color of the (hypothetical) dichromate but nothing happened!

I added some ammonia before acidifying the solution, nothing as well.

1st: Is this method the right one to obtain chromate/dichromate?
2nd: If yes, why didn't the orange color appear?
Note that the chromate ion $\ce{CrO4^{2-}}$ has chromium in the +6 oxidation state like dichromate $\ce{Cr2O7^{2-}}$. Chromate is yellow, dichromate is orange. 

From the Wikipedia article on sodium chromate: sodium chromate is formed by reaction of dichromate with hydroxide:

$$\ce{Na2Cr2O7 + 2NaOH -&gt; 2Na2CrO4 + H2O}$$

You may be making sodium dichromate, but the strongly basic conditions are converting it to sodium chromate.
