摘要:
The mould with an internal shaping core for manufacturing thin-walled blown glass objects, for example Christmas tree decorations, consists of at least two semi-moulds with a free mould division axes, matched and connected disjointly with an opening for inserting the stay for blowing the air inside the mould. The shaping core fastened inside the mould is stabilised in at least one seat or lock through full closure of both semi-moulds. In the thus shaped spatial cavity a heated glass bulb is blown up which is given a final, monolithic complex shape.
摘要:
The invention concerns a method for producing Christmas tree decorations consisting of several blown glass objects assembled together consisting in: implanting a seat in the base element body which can freely receive the tenons of the other element. Before they are assembled the seat and the tenon are coated with a quick-setting plastic binder such that the seat-tenon assembly is slightly elastic. The unpolished Christmas tree decoration can therefore be easily subjected to further surface treatment such as being painted, coated with paste or covered with brocade and the like.
