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": "27.5", "type": "Glass_Compound_Amount", "constituent": "Ge", "unit": "mol", "material": "xx"}
{"value": "4.5", "type": "Glass_Compound_Amount", "constituent": "Ti", "unit": "mol", "material": "xx"}
{"value": "67.0", "type": "Glass_Compound_Amount", "constituent": "O", "unit": "mol", "material": "xx"}
{"value": "0.9", "type": "Glass_Compound_Amount", "constituent": "Er", "unit": "mol", "material": "xx"}
{"value": "3.6", "type": "Other"}
