Do I have to sand water clear casting resin? Answered

I'm a COMPLETE novice when it comes to resin of any kind. But I'd like to start doing my own flower castings as a hobbie. I was thinking of buying water clear casting resin- I want to be able to see the detail in the pieces but recently after watching a few videos and researching, i've found that I have to go through a sanding process. I thought that if I buy water clear then I wouldn't have to sand it because you will see the details? am I wrong in thinking this. Also,  if I cast items in glass jars will they come out super clear?


Use a silicone mold. The end surface will be as good as the surface of the mold.

PS Flowers MUST br totally dry to cast effectivly.

Only sand if the mold cavity is rough and not perfectly flat.. I use tight saran wrap or inside if an egg shell with slow cure rate, pull a vacuum and slowly let air back in to collapse any bubbles..
