This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
3 T* c/ {+ V2 k/ R O0 V1. wash everything with broiling water, soak glutine rice overnight , using a bowl, cook inside microwave cooker ,( my rice cooker not easy to clean to oil-free stage), rice was properly cooked ( similar to sticky rice in dimsum restaurant ), left at table to cool down to same temp as back of hand, stir occaionly, sprinkle and mix 1 flat teaspoon of wine yearst ( white color, look like the fruit of lychi ), pour content into a jam jar , half full, put a piece of ceram wrap over jam, screw cap , put jar inside cupboard.
$ }9 \( `+ X+ y3 h8 n* M/ L% [ v2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.) c2 i+ h; `3 i9 K
Next day, more bubbling activitiy everywhere. slight alcohol smell.' y$ c& p* j9 ^ T+ U1 K& p
in 3rd day rice broke down from it's shape, stronger alcohol smell, truns darker color

Conclusion -- when compare with your steps, these are the reasons of failure :-
