After spending wayyyy too much time on this, I have come to the conclusion that when lard turns "bad" it actually just gets rancid, and not transparent. There was nothing stating how it would get transparent but multiple accounts of it becoming foul in taste or smell. Lard can't be transparent, so even if the OP meant if lard is sold as transparent it isn't as good as thick lard, it wouldn't make sense.

Some Lard Tips For All of You:
-If you store lard properly in the refirgerator in an air-tight container it will last about a year
-If you decide to freeze it, in an air-tight container it will last over 3 years
-You should never try freezing lard in its original packaging. this will result in freezer burn and change of texture
-Defrosted lard can keep in the refrigerator safely without spoiling for up to 6 months.
-Never store your lard in an open container in one of your kitchen cabinets because mice, rats and insects will feed on it and cause it too spoil or become contaminated with fecal matter and harmful bacteria that is dangerous to your health.

Remember if you aren't sure if your lard has gone bad or not - just throw it out to be safe.

Stay lard safe everyone!
