The art of consuming concentrates has undergone several evolutions over the years. Each advancement in dabbing has improved the efficiency of the experience, leading to more flavorful dabs as well as a more convenient cleanup. This evolution is probably best illustrated by the massive shift that occurred when connoisseurs first stepped away from hot dabs off of metal nails and moved on to new techniques in the quest for flavor.

When the first amber-colored extracts surfaced, concentrate fans were happy just to have a way to consume them—even if it meant using a harsh red-hot knife. The hot-knife concept was the basis for the first bongs made for concentrate consumption. These were made with skillets, which were like hot plates directly under a tube that filtered vapors through water for cooler, larger hits.

The next innovation in concentrate consumption represented a step forward and two steps back. It was a nail that fit into male joints with a borosilicate globe or dome around it to partially keep the vapor from escaping. This required glass water pipes to be made with male joints for the first time.

Additionally, the dome would have to be removed before each dab, and it would sometimes get stuck once oil built up in the joint. Thanks to the mess and extra steps it required, it didn’t take long for domes and nails to be replaced by the simplified, all-in-one domeless nail.

This is when the transition to lower-temperature dabs for flavor and comfort began. People started to let their domeless nails cool for some time after heating them up, which made hits less harsh.
