Small sintering ceramics The fiber box type electric furnace then uses cotton strips to absorb hydrogen peroxide or "84 disinfectant" to apply on the black spot line, "fishing" out the black matter, Ma Fulu It usually takes half an hour. In case of deep black, change into cotton strips several times and wash repeatedly until the black is completely washed. Note that each fragment and several joint surfaces of the fragment should be cleaned with hydrogen peroxide.
7. Wood used after filling Sandpaper Polish and smooth, and use porcelain at the gap putty Fill and level with fine terrazzo paper. Most of the adhesives used in the past are natural Vegetable gum The repaired porcelain seam is prone to discoloration, which can be easily recognized at a glance. Now when bonding Heat small workpieces in muffle furnace , use colorless and transparent epoxy Resin and polymer synthetic materials are not easy to change color, feel and fishing "the appearance of the muffle is the same as the original objects. And the materials to be repaired are knocked.
1. First, trace the relationship between all the fragments and artifacts with a paper head, then cut and splice them into a picture. The furnace will mark the relationship between the black matter and the fragments.
3. Special cleaning is required. Burn muffle furnace sample at 650 ℃ ！ Use hydrogen peroxide or "84 disinfectant" to clean the crack and notch on the main utensil. Try to reduce the color difference in the seam as much as possible, so that there is no trace on the bonded fitting surface.
5. Before bonding, wait until several joint surfaces of the fragments are dry, and then use epoxy resin or 502 glue suitable for ceramics for bonding. Glue shall be applied as little as possible at the joint between tiles to prevent excessive air gap
