I'm curious if there are any chemicals which will dissolve a flame treated 50/50 mix of Alumina Hydrate and Kaolin from Soda Lime, Lead and Borosilicate glass surfaces.

The 50/50 mix is used as a bead release for when a lampworker melts the above mentioned glass types onto a metal mandrel and is used to allow the removal of the bead later on. The mix itself is quite difficult to clean from the bead which led me to wonder if there are chemicals that would dissolve the mixture of alumina hydrate and kaolin while not damaging the glass.

Some mixes include other ingredients such as alumina calcinate,  graphite and diatomaceous earth in addition or separately to the previously mentioned ingredients to which I'm unsure if it would effect the outcome of possible chemicals that would work.

Any and all information is appreciated.
