Citrazinic acid; fail or success?

Hey people.

I tried making Citrazinic Acid today, sounded like a easy project I could do without proper lab equipment.
But I'm not sure whether I was successful or failed at this.
What I did was;

1. Weighed up 11 grams of Citric Acid, and 5 grams of Ammonium Carbonate

2. Put 2g of citric acid in pyrex beaker and placed it on electric stove, turned the stove up to lowest setting( I don't have a thermometer, but I know
that citric acids melts at 153Celsius).

3. Waited for the 2g of citric acid to melt, then I mixed the remaining Acid(9g) with the Ammonium carbonate, and poured them into the beaker.
(I assumed that the (NH₄)₂CO₃ would've decomposed if I had poured it into the pyrex beaker without heating citric acid to melting point first)

4. Stirred the liquid mix of (NH₄)₂CO₃ and Citric acid, making sure that everything reacted. Also added some more Ammonium Carbonate, ~0,5g.

I heated it for about 15 minutes, might've been too long. First it went from white to slightly yellow, then yellow, then brown.

AND HERE'S WHAT I ENDED UP WITH:
(6g in total)


Powder/crushed crystals, excuse the bad quality.

This gets syrup-ish when heated, but is solid/crystal at room temperature.

It would help, if you would cite the references you used and above all measure the melting point. Surely you don't expect people are able to do spectroscopic analyses via pictures?
