Glassblower's Questions and Answers

  1. What type of glass is created opal compatible with?

    Created opal is compatible with borosilicate glass.

  2. What is the best color to use?

    As far as color goes, its personal preference. All colors work the same in the glass. The darker colors reflect wonderfully and stand out a lot. White or crystal blend into the glass and look wonderful.

  3. Can I use natural opal in glass?

    No, the opal must be created opal, natural or imitation opal will not work.

  4. Can I buy a large piece of rough gilson created opal and break it up for small applications and it won't affect the stone?

    You can break up your gilson created opal easily with tile nippers or saw and it won't hurt the stone what so ever.

  5. What are cabochons, doublets and triplets and can they be used it glass?

    Cabochons are stone cut with only one type of material. In our case cabochons are pure gilson created opal and are perfect for glass.

    Doublets are opal with 1 layer of something stuck to the opal, therefore it won't work.

    Triplettes are opal sandwiched between 2 somethings, and therefore it won't work.

  6. Does a carat weigh under a gram? Whats the conversion?

    5 carats to 1 gram

  7. Does created opal move at all once in the glass? Can it be shaped in the flame? If i get a big piece of gilson created opal, can i blow it?

    I get this question alot. No you can't "blow opal" like you blow glass. To be honest I have never tried but from everything I know about the material I am sure its impossible...

    You can use it like a frit and blow the glass that its stuck to....

  8. If it is used like frit will it flow and smooth out on the glass or would it just sink in in sharp edged looking chunks?

    If you try to melt the opal into the glass it will retain its shape and color, it won't melt like glass does at all.... and if you use it like frit I would strongly suggest not letting the flame touch the opal too much...
