縄文時代では唯一の出土資料であるウルシ樹液採取の痕跡を持つ杭に関しては，その傷の在り方についていくつかの課題が残されていた。その解決のために，石器によるウルシ樹液採取実験を行った。その結果と出土資料の再検討から，縄文人がウルシ林を維持管理するためにウルシの木を間伐していたことを論証し，出土した杭はその有効利用であったことを指摘した。
多数が出土している漆液容器には，保管用・調整加工用・塗布用・補修用等の用途が想定され，残存している漆の種類や状況から，それぞれが漆工のどの工程に対応する漆液容器かを検討し，そして，個々の容器の分析から，容量や使用方法を推定した。
漆塗り土器については，黒色漆塗り土器に関して二つの課題を設定した。一つは，塗膜の状態から黒色漆塗り土器を2種類に大別し，それぞれが高温塗布と常温塗布に対応するという仮説を立て，それを実体顕微鏡による塗膜の表面観察・断面観察と高温塗布実験の結果から検討した。もう一つは，炭化物付着が顕著な漆塗り土器や，漆そのものが炭化している土器，漆塗膜が火で炙られている土器の存在から，漆塗り土器を火に掛けることについて検討した。
最後に土器の漆補修に関して，損傷の仕方と補修方法・補修に使用する漆の種類の対応関係を明らかにし，具体的な補修技術について検討した。, Based on the diverse lacquerwork-related artefacts excavated from the Shimo-yakebe site, this paper reproduces the lacquerwork techniques of the Jomon period.
Concerning the stakes, which are the only excavated materials of the Jomon period showing traces of collecting Japanese lacquer tree sap, several issues remain unanswered regarding the style of the cuts. To solve these issues, an experiment to collect Japanese lacquer tree sap using stoneware was conducted. From the results and re-examination of the excavated materials, this paper proves that the Jomon people cut down the Japanese lacquer trees as a form of forestry to maintain the lacquer tree woods, and describes that the excavated stakes demonstrate the efficient use of the cut trees.
Large numbers of containers for lacquer tree sap were excavated, and it can be assumed that they were used for storage, adjusting and processing, coating, or repair. From the species and conditions of the remaining lacquer, containers were examined to first establish to which process of the lacquerwork they corresponded; further analysis of each container revealed the capacity and inferred use.
For lacquered pottery, two issues were raised regarding black-lacquered pottery. The first was to establish the temperature used for coating, by broadly dividing the artefacts into two types according to the coating condition. A hypothesis was then formulated that each artefact was either high temperature coated or normal temperature coated. The hypothesis was examined based on observation by stereoscopic microscope of the coating surface and section, and the results of a high-temperature coating experiment.
The second issue concerned the nature and practice of putting lacquered pottery onto a fire. Examinations were carried out with a focus on three types of pottery: lacquered pottery with a distinguished adhesion of carbides; pottery with carbonized lacquer; and pottery with a lacquer coating subjected to some degree of light heat.
Finally, in regard to the repair of pottery lacquer, examination was conducted to establish the specific repair techniques by clarifying the relation of the damage condition to the repair method and the type of lacquer used.},
