This was my failure
It wa summer time room temp was 30C, I was experiment with a small amount inside a Robertson jam jar.
4 N% k B2 \" t* o1. 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.& G) \4 G3 V* b/ [& T
2. 2 to 3 hours later, peek at the jar, noticed some bubbling activity inside jar,.* ?+ V6 ~+ C$ U- X! c% {! u

4th day very little bubbling, shaked jar hoping to improve activity, (this could be the mistake)

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

1. 1/2 jar of air inside jar might has germs that ruined reaction
