You are provided with a table from a material science paper. Here are JSON templates for two types of numeric cells: "Other" and "Glass_Compound_Amount":
{"value": "xx", "type": "Other"}
{"value": "xx", "type": "Glass_Compound_Amount", "constituent": "xx", "unit": "xx", "material": "xx"}

Please describe all numeric cells in the above table following the JSON templates (proceeding by row in a left-right, top-down direction). For each cell, output one JSON description per line. For any unanswerable attributes in the templates, set their value to the placeholder "xx".

Cell Description:
{"value": "2", "type": "Other"}
{"value": "5", "type": "Other"}
{"value": "8", "type": "Other"}
{"value": "3", "type": "Other"}
{"value": "6", "type": "Other"}
{"value": "9", "type": "Other"}
{"value": "1", "type": "Other"}
{"value": "4", "type": "Other"}
