Problems with encasing sculpted items

[ginol]

Hi everyone!
I am trying to incorporate a number of previously sculpted items into a single encased pendant but, I am running into the same problems regardless of what I try.
Problems:
1) When I encase each sculpted item, I end up with a thin visible boundary line at the interface between the sculpted item and the encasing clear (Most likely I am trapping a thin layer of air at the interfaces). I have found that the amount of heat required to remove the line ( make the line coalesce into an air bubble?) is excessive, leading to distortion and movement of the sculpted item.
2) I often have difficulties in blending layers of encasing clear, especially when I am trying to fill crevices between the sculped items. What I see is a line between the layers of clear (trapped air?). Again, in order to get rid of these lines, I need to apply too much heat and I end up with distorsion and movement of the sculpted items.
3) I would like the sculpted items to stay where I place them. Currently, they move as I melt-in the encasing clear.

Any advice as to how I may be able to solve these problems?

Your help will be greatly appreciated!

did you try a stump sucker, works much better in soft glass than boro, hard to not have air but possible, its a matter of preheating the pieces, raging heat on the blob you add to encase. what kind of sculptures are you trying to encase? and into what final shape?
good luck!

In one case, I am trying to encase small implosions.

Thank you for your reply.

Thank you for your reply.

Also, make sure your implosions are squeaky clean. You can't have touched them with your bare hands even once or it will show.
