Wheel Weight Inexplicably Increases 20 gms In 2 Weeks

This is the double tubed wheel w/ sealant in both tubes. It may have picked up a little dust but not 20 gms worth.
The bike is usually locked up outside in the heat under a make shift cover. Since it was first weighed 2 weeks ago both tubes have been pumped up twice w/o loss of sealant and ridden about 100 km on 60 C pavement.
The interest in wheel weight is that water based sealant may evaporate in the heat with the wheel getting _lighter_ not heavier.
The kitchen scales seem accurate enough weighing out food.
Absorbed something - maybe water, oils from tarmac?
But I'd mainly suspect the scales, and their margin of error at
different temperatures.
