英国采购需求：釉粉、多聚甲醛、水性、添加剂、甲醛、酚醛树脂

I'm working on a small pottery project here in Tanzania and I'm looking for a kilo of zirconium silicate. Could you provide me with detailed information regarding its availability? I'm particularly interested in the lead time for shipping, as well as any specific packaging options you might have. Additionally, I would appreciate it if you could send me your pricing details, including any bulk purchase discounts and shipping costs. If there are any minimum order requirements or other relevant information I should know, please include that as well. Looking forward to your prompt response!
