An ice catcher, placed in the neck area of a bong, is a popular attachment for the glass beaker bong. It is in the form of in-built, little notches for holding ice cubes and cooling the smoke down within the piece. This is a popular feature for long neck glass bongs, but the melting ice increases the level of water in the chamber, making it unwieldy and messy. There are worries related to spillage and high waterline that leads to splash-back in the face, causing huge problems for smokers. One way to prevent the problem is the use of glycerin coils with the glass beaker bong.

These coils cool down the smoke just like the ice, but there are no melting issues. Even small bongs can cool the smoke down using this attachment to improve the experiences. Another name for this is the condenser coil and these freezable pieces remain incorporated into the bong. Such add-ons function as its neck. Glycerin being non-toxic is a popular ingredient in various products and the fatty acids it contains are a part of the food consumed as preservatives and sweeteners. The melting point is high and the consistency is gel-like. Upon freezing, they turn into a desirable alternative for the ice added to a glass beaker bong.

They remain frozen and in place for a longer time, and the freezing is quick. So, users do not need to wait for hours before use. The sections of these glycerin coils are removable. So, it reduces the chance of breaking the bong when handling it. Frozen coils slip into the body of the bong easily and it accommodates everything from an inline percolator to the beaker base, to create double-punch filtration. The glycerin coils work with clips to attach or remove from the bong easily. This plastic clamp is an effective feature to attach to the reclaimers, adapters, and drop down into the base portion of a glass beaker bong.

The function of the clip is to maintain its structural integrity and prevent the breaking and slipping out of the coil from the bong. Freezable pipes use glycerin to remain cool. They are a useful attachment for smokers looking for a cool hit without putting together an entire bong. The glycerin coils provided the extra functionality related to the percolators with filtration around and through the coils. This filtration process works just like the regular coil percolators do.
