Glassware with silicone support

A glass dish suitable for use in cooking applications, the glass dish comprising:

• a substantially homogenous glass body defining at least one side wall, an upper extent and a bottom surface having a predetermined thickness To;
• a channel formed in the bottom surface of the body, the channel having an open end and an inner surface, the inner surface comprising a substantially planar bottom wall, an inner sidewall and an outer sidewall, the channel having a predetermined depth Do in the range of 0.040 to 0.080 inches and the open end of the channel having a predetermined width Wo in the range of 0.25 to 0.50 inches, the channel conforming to the relationships Wo/Do=3 to 13 and Do/To=0.2 to 0.6;
• and
• a silicone support comprising a protruding extent and an interior extent, the interior extent of the silicone support disposed within the channel, at least a portion of the interior extent of the silicone support directly contacting at least a portion of the inner surface and being adhered thereto by chemical adhesion, wherein the protruding extent of the silicone support extends to a height Ho of at least 0.010 inches beyond the open end of the channel, the silicone support having a melting point greater than 350° F.

A microwavable glass dish suitable for use in microwave cooking applications, the glass dish comprising:

• a substantially homogenous glass body defining at least one side wall, an upper extent and a bottom surface, the glass body having a first thermal insulative value;
• a channel formed in at least a portion of the bottom surface of the glass body, the channel having an open end and an inner surface, the inner surface comprising a bottom wall, an inner sidewall and an outer sidewall;
• and
• a silicone support comprising a protruding extent and an interior extent, the interior extent of the silicone support disposed within the channel, at least a portion of the interior extent of the silicone support directly contacting at least a portion of the inner surface and being adhered to the inner surface of the channel by chemical adhesion, wherein the protruding extent of the silicone support protrudes beyond the open end of the channel, wherein the silicone support has a melting point greater than 350° F., and wherein the silicone support has a second thermal insulative value, the second thermal insulative value being greater than the first thermal insulative value.

A method of manufacturing a glass dish with a silicone support comprising the steps of:

• providing a glass dish defining at least one side wall and a bottom surface, the dish having a circumferential channel formed in the bottom surface, the channel having an internal volume;
• rotating the glass dish at a first rotation speed through approximately 360 degrees;
• through the approximately 360 degrees of the rotating step at the first rotation speed, applying a first predetermined volume of silicone in an uninterrupted flow at first flow rate to the channel of the dish, wherein the first predetermined volume of silicone is greater than the internal volume of the channel so that the silicone fills the channel and protrudes beyond an upper extent of the channel, the first rotation speed and the first flow rate coordinated to achieve a first application density, wherein the step of applying the first predetermined volume of silicone occurs at the same time as the step of rotating the glass dish at the first rotation speed;
• rotating the glass dish at a second rotation speed beyond the approximately 360 degrees;
• applying a second predetermined volume of silicone in an uninterrupted flow at a second flow rate to the channel of the dish to form an overlap of the applied silicone, the second rotation speed and the second flow rate being coordinated to achieve a second application density, the second application density being less than the first application density, wherein the step of applying the second predetermined volume of silicone occurs at the same time as the step of rotating the glass dish at the second rotation speed;
• and
• curing the silicone to form a substantially seamless silicone support.
