I would like to sanitize the glass seasoning container thoroughly, but is it okay to boil it in boiling water?
Since it is a glass container that holds food, people often try to sanitize it with boiling water before the first use. It is necessary to check whether boiling water sanitization or dishwasher use is possible for both the glass and the lid.
The container body is not heat-resistant glass, so it must not be boiled in boiling water, and as for the dishwasher, only the glass body excluding the lid can be placed in it.
The glass body can be used in a dishwasher, but boiling water sanitization by placing it in boiling water cannot be done[1][2]. This is because the container of the Toyo Sasaki white glass seasoning container 485ml is not heat-resistant glass that withstands rapid temperature changes[3]. Placing the container directly into boiling water carries a high risk of the glass breaking due to temperature differences, so freshly boiled broth or hot sauce must also be poured only after cooling the steam off once[4].
Even when using a dishwasher, the standards for the body and the lid are different. Only the clear glass container should be put in the dishwasher, and the lid must be separated and hand-washed with a soft sponge[5]. This is because the high-temperature heat and strong water pressure inside the dishwasher can warp the plastic parts of the lid and reduce airtightness.

The exact heat-resistant temperatures that the glass body and lid parts can each withstand have not yet been confirmed.
