I wanted to reply to everyone regarding the glowing glass..and also thank everyone for their interest in the XHale brand.
Let me preface this post by saying that I can only vouch for products that we manufacture. XHale is one of only two branded American glass manufacturers that still manufacture here in the States...allowing us to have superior quality control.
Basically, the products that simply require a "charge" under a lightbulb incorporate a phosphorus chemical that is first baked into the glass , then crushed into a powder. The powder is then added to the toys in the manufacturing process. When a consumer receives a finished XHale product, the phosphorus glass has already been completely encased in borosilicate glass, which is 100% non-porous. It is impossible to come into contact with any material inside of the glass. There really is no way to "safe" cut corners when working with glass (ultimately saving time and labor costs), and that is why you do not see this type of product coming from overseas...it's just too cost ineffective to properly manufacture this type of product on a larger production line.
For those of you interested in glowing products, stay tuned... the company that supplies us with the glowing glass powder is working on some great new glow in the dark glass which we will be working with very soon!
I also wanted to take the opportunity to welcome any and all questions regarding glass toys...not just XHale products, but toys from anyone. We are experts in this field and our creative designer and Vice President of the company Kevin Kroldart will be answering your questions and most importantly educating you, as consumers on what to look for and how to monitor and justfy what you are paying for when buying glass.
