I'm not really a gram counter but one thing I have been doing that seems to help me has been to construct a sm. food warmer/lamp.
I have taken a 1/2 sz. soda can and cut a 2x2 (?) in window near the bottom edge. I cut piece of plastic soda bottle to fit
the can so I can use it as a lamp. The plastic window grabs the can just fine and is far enough from the candle flame so it will not melt.
To use it as a warmer I just set my metal cup or pot on top and the tub candle helps to keep food or my coffee warm.
Because I only have a small viewing window I don't need to worry much about the can crushing from the weight.
In total the Lamp/warmer might weight 1-1.5 oz. with one tub candle.
